Simple Mathematcal Pattern Describes Shape of Neuron 'Jungle'

Neurons look remarkably like trees, and connect to other cells with many branches that effectively act like wires in an electrical circuit, carrying impulses that represent sensation, emotion, thought and action.

Over 100 years ago, Santiago Ramon y Cajal, the father of modern neuroscience, sought to systematically describe the shapes of neurons, and was convinced that there must be a unifying principle underlying their diversity.

Cajal proposed that neurons spread out their branches so as to use as little wiring as possible to reach other cells in the network. Reducing the amount of wiring between cells provides additional space to pack more neurons into the brain, and therefore increases its processing power.

New work by UCL neuroscientists, published recently in Proceedings of the National Academy of Sciences, has revisited this century-old hypothesis using modern computational methods. They show that a simple computer program which connects points with as little wiring as possible can produce tree-like shapes which are indistinguishable from real neurons -- and also happen to be very beautiful. They also show that the shape of neurons follows a simple mathematical relationship called a power law.

Power laws have been shown to be common across the natural world, and often point to simple rules underlying complex structures. Dr Herman Cuntz (UCL Wolfson Institute for Biomedical Research) and colleagues find that the power law holds true for many types of neurons gathered from across the animal kingdom, providing strong evidence for Ramon y Cajal's general principle.

The UCL team further tested the theory by examining neurons in the olfactory bulb, a part of the brain where new brain cells are constantly being formed. These neurons grow and form new connections even in the adult brain, and therefore provide a unique window into the rules behind the development of neural trees in a mature neural circuit.

The team analysed the change in shape of the newborn olfactory neurons over several days, and found that the growth of these neurons also follow the power law, providing further evidence to support the theory.
Dr Hermann Cuntz said: "The ultimate goal of neuroscience is to understand how the impenetrable neural jungle can give rise to the complexity of behaviour.

"Our findings confirm Cajal's original far-reaching insight that there is a simple pattern behind the circuitry, and provides hope that neuroscientists will someday be able to see the forest for the trees."

'Facebook for Animals' Tested On Wild Great Tits

How animals associate in groups can have important consequences in terms of the health and survival of both individuals and whole populations; influencing factors such as the spread of disease and the ability to find food or mates.

But revealing the networks underlying animal societies is a challenge when a large amount of fieldwork data consists of a long stream of automated observations of the times and locations of individuals, leaving scientists to try and reconstruct the 'big picture' of how individuals are connected.

The new approach can automatically identify periods of intense social activity within a large number of observations -- in this example around one million observations of wild great tits (Parus major). This makes it possible to examine these periods in greater detail and calculate which individuals are real 'friends', rather than random passers-by, and even which are looking to pair up and mate.

A report of the research is published in this week's Journal of the Royal Society Interface.

'If you think of the data about you in Facebook it records things like who you are friends with, where you've been, and what you share with others,' said Ioannis Psorakis of Oxford University's Department of Engineering Science, who led the research. 'What we have shown is that we can analyse data about individual animals, in this case great tits, to construct a 'Facebook for animals' revealing who affiliates with who, who are members of the same group, and which birds are regularly going to the same gatherings or 'events.''

They team tested the new technique on data from two breeding seasons of wild great tits (August 2007-March 2008 and August 2008-March 2009). The data came from transponders attached to thousands of birds and sensors that logged when individuals appeared at any one of 67 bird feeders spread throughout Wytham Woods, Oxford.

The researchers found that their predictions from this data about which birds were 'friends' that regularly foraged for food together, as well as which birds were starting the process of pairing up or were already in a pair, matched visual observations made by zoologists.

'What we've shown is that our technique can extract information about the networks that bind individuals together by sampling and analysing their mobility patterns,' said Ioannis Psorakis. 'Our approach makes it possible to look at huge amounts of data without having to decide what time resolution is best to extract meaning -- the model evaluates this automatically. This is just the first exalple of how zoologists are beginning to use our method to explore social networks of animals in a 'big data' context.'

Early results from the work with great tits suggest that individual birds do not participate in flocks at random, but have a bias towards other members of the population they interact with. The majority of networks extracted using the approach are strongly clustered, and in such tight bird communities, individuals forage together and interact with their current or future mating partner.

This approach is being used not only in great tits, but also in a mix of wild-bird social networks, exploring the animal sociality at an inter-species level. Some of the most important future steps in this work are to combine the 'social' information available through this method, with other types of information: for example combining it with genetic data is enabling researchers to explore the genetic basis of sociality: do genetically similar individuals attract each other, or is it the other way round? Can we find specific areas of the genome that account for gregariousness?

The work could also help researchers understand how information spreads through animal populations. Tits are a famous exemplar of social learning: for instance, the habit of pecking open milk bottles on doorsteps to get access to cream spread rapidly through England in the mid 20th Century. The new approach is helping scientists to test how specific social structures help or hinder the spread of novel information from individual to individual.

What Does an Electronic Component’s Name Means?

When you are arranging a circuit board to make a certain electronic devices or to repair a damaged board, you certainly have to know every electronic component that is mounted or etched on it. There are various electronic components that can be placed on a circuit board and each of those components has a specific name based on JEDEC (Joint Electron Devices Engineering Council) nomenclature. Each named component has specific characteristics. If you buy a 2N2222 bipolar junction transistor, for example, you are referring to a metal-canned transistor that has a maximum of 625 miliwatts of power dissipation and a maximum of 60 volts of voltage rating. Of course this nomenclature system is established because a specific type of electronic component has many variants. The aforementioned bipolar junction transistor, for example, has an almost similar duplicate called PN2222, whose only difference from this transistor is that PN2222 uses plastic can instead of metal can. If you want to buy a certain electronic component to be mounted on your circuit board, make sure you know the name of the component that you want to buy.

Among many electronic components that you can buy from any electronic stores, either local or online, signal diode is possibly one of components that have the most variants. The primary function of such signal diodes as 1N4148 diode is to force electricity to flow to only one direction. Signal diodes are made from such semiconductors as germanium and silicone. Semiconductors are materials that neither allow electricity to flow as effectively as it does on conductors nor resist electricity as strongly as insulators do. Diode is made from semiconductor so that it can resist electricity to flow alternatively in two directions and at the same time allow electricity to flow in one direction. Signal diode has many uses, one of which is to emit light when current flows through it. A variant of diode that is used for this function is called LED.

Just like other named electronic components, a signal diode with a specific name also has specific characteristics. BAV99 signal diode, for example, is one whose maximum repetitive reverse voltage is 70 volts, average rectified forward current is 200 mA, storage temperature range is between -55 to 150 degree Celsius, and operating junction temperature range is the same with that of its storage temperature. Make sure you define the name of signal diode that you want to buy so that you don’t choose the wrong item.

People need some device to help their life more easily than the past time. The simple example is for the past time people use the animal for the land to grow their plant, but for tims time people have been used the machine to help their job. They don’t use some animal again. They just using land machine and the other device that’s support their activity. The others example is for the past, people watch the televition by using black and white colour. The next technology people has been used the colour televition that’s watch in their home. 

The technology not stopped from there, people continue to developt the technology. They built new technology for gets the beautiful images that’s help the people for the better images. People developt the image viewer to be best quality images with using VGA cable. The next generation for the cable that support the better images is developtment for VGA itself. Now, there is VGA over Cat5 that has a better images better than the last VGA. Technology always growth with better and improvement the last technology. They always improve the technology for help to human needed. 

The other improvement of technology is make for better life than before. Technology not only stopped from those, it always improve and make the others device that’s support some electronic ones. Technology not off from the electrician, they need electricity to support they power. That’s new era for developt technology in electronic device.

Just head over to Capzles main page and slick on sign up. Once logged in you can start creating your new Capzle by clicking on ' create' on the upper tab.

It is like creating a sideshow but just with more interaction and animation. You need to fill in the title and description for each Capzle you make. You can also add tags and select the category under which you want to place it. Click on ' add content' to add videos, docs, PDFs, sideshows, photos ..etc.The next step is to choose a design for your Capzle by selecting the appropriate color, theme and background. Once done add you own music and choose your privacy setting whether you want it public or private. Now that your Capzle is complete you can share it using the sharing options provided there for you.

A List of Top Educational Infographics ( Slideshow )

Infographics are gaining a strong foothold in the field of education.We are witnessing a sweeping surge in infographics talking about educational issues but some of the  companies that create them are not really interested in education but rather in SEO ( Search Engine Optimization ). Anyway I will not engage you in this topic here for it is not what this post is about and . For me as long as the infographic is based on solid background data and tackles the subjects we are interested in then why not thumbing it up,  we do not care whether the person who created it wants just to draw traffic to his or her website but as long as the infographic itself contains valid and correct data then why not share it.The aim is learning and not judging people's intentions after all. I said this because  I have been engaged in such a debate about infographics in one of the  webinars I held recently and I just want to make it clear once for all.


infographic



That being said, I would like to insist on the validity and usability of the infographics I include in my blog. Before I share one here it  has to go through a filtering process including a small investigation about the creator of the infographic  and many many  other things. Anyway and without any further ado, the following are some of the popular infographics that have been making rounds online and that I have also included in Educational Technology and Mobile Learning.

A List of Free Apps for Students with Hearing and Visual Impairment

People with disabilities have just the same right to enjoy life the same way normal people do. It really rips the heart to see someone with a certain impairment trying hard to do the simplest things in life with such a hardship. These people struggle with the day to day situations that we might simply take for granted or do not really have an entire appreciation of .

Imagine having to teach visually impaired students or those with hearing problems.Do you think they are having an easy school life like the other mates ? The answer is definitely no. They are in fact doubling the efforts to catch up with the rest of the class. Thankfully with the integration of technology into education we can help these students and give them a leg up.

Reach out for mobile technology apps and you will find a plethora of educational apps designed just to help students with different impairments. I know not everybody can have access to them because mobile technology gadgets to run them on such as iDevices are still scant in schools but this is not an excuse not to introduce some to your students. They might get their parents to buy them these devices. Additionally, there is an ongoing revolution in the world of education due to mobile technology boom and schools are now planning to get iPads and use digital textbooks. Some in the United States have already started experimenting the use of digital Chrome Books. That is really very promising and we are very sure that this is just the beginning and there is more to come.

In this regard, The Best of Mobile Technology has gathered and reviewed some of the apps that you can use with your students. These apps are for students with hearing and visual impairement. I have included these apps into different presentations to make it easy for you to share and access them anytime you want.

Infographic on The Digital Classroom

There is a growing buzz in the educational sphere around digital textbooks. Since the launch of iBooks 2 and iBooks Author and the educational technology experts are investigating the potential of these new revolutionary tools. Google is not disassociated from the scene and it is trying to take a foothold with a huge project called Chrome books. So the question that really needs an urgent answer is : are  we in front of  a ferocious competition between Google and Apple to gain more sales via investing in education or is it really the beginning of a digital revolution in education?






Anyway I can not provide an answer yet as it is too early to judge the intentions behind these huge moves but what is really amazing is the fact that the infographic world is keeping track of these innovations and is providing us with awesome infographics too. The Digital Classroom is an example. There are quite many others that cover this issue and that I have included in previous posts here, you can check out Educational Infographics section to learn more.

Online Video Training Brings the Classroom to Your iPod


Online video training sites typically offer video or audio recordings of classes taught at colleges and universities across the nation. Users can tune in to these free-of-charge class sessions and follow along. While students can’t get credit for classes taken on YouTube, and iTunes U – as these do not offer degrees – the information in the lectures is often the same as what students get in live classes.




Online Video Training: Key Benefits

Online video training is growing in popularity. In August 2010, Apple announced iTunes U had surpassed 300 million downloads after only three years in operation. MIT’s OpenCourseWare project continues to add new classes at the rate of 50 a year, and YouTube EDU offers over 200 complete courses. Corporations like Volvo are also adopting the new technology to personalize training across thousands of employees worldwide.
Students are flocking to video training options because of its advantages such as:
  • Overcoming barriers of distance. In August 2010, American surgeons began giving counterparts in Nepal live video instruction on surgical techniques. This was a dramatic illustration of the power of online video training to overcome barriers of distance.
  • Facilitating frequent training. In some fields, and especially in technology, change happens rapidly. Online tech training is one way to meet the demand for frequent updates of knowledge and techniques. Professionals who many not have time or money to pay for refresher courses can take advantage of online video training to stay abreast of current trends or brush up before certification or licensing exams.
  • Using up-to-date communication styles. A Department of Education analysis of over a thousand studies of online learning found that on average, students did better under online learning conditions than with face-to-face instruction. A survey of more than 200 medical students found that an overwhelming majority believed that technology — including video game applications — would enhance their instruction.
  • Enhancing information retention. One study found that introducing a video element to instructional programs enhanced long-term retention of the material, perhaps because of the heightened visual dimension of the content.

Online Video Training: Best Practices

Clearly, online video training has several potential applications and benefits, but not all online video training is created equal. Users of online video training should make the distinction between the following forms of training:
  • Vendor-generated video. Vendors of various products, especially in the realm of technology, often produce videos instructing users on the correct application of their products. Online tech training using vendor-generated videos for specific products can be very effective, as long as the user understands that the material does not represent an objective overview of the entire field.
  • In-house videos. In-house videos can be valuable where the focus is on company policy or proprietary techniques. Where broader subject matter is concerned, it can be helpful to introduce outside expertise.
  • Accredited, academic online video training. Material produced by accredited academic institutions is likely to contain the highest-quality content, and can also be part of a formal degree or certification program which allows customers and/or potential employers to recognize the level of training an individual has received. In short, formal programs make sure that the acquired skills are not only useful, but that they are marketable too.
Online training can be a great resource, but it does have its limitations. For one thing, sites like YouTube don’t generally vouch for the quality of the instruction, meaning some courses may be pure brilliance while others may be little more than a series of PowerPoint slides and a lecturer droning on in the background. And unlike online computer certifications, most video training programs don’t allow for interactivity, so if students get confused, they’re on their own. Students needing in-depth instruction or those who are looking to tackle highly technical fields may find degree programs or accredited certification courses better meet their needs.
Online video training can come in many forms, but in the right format, it’s a valuable tool to update skills, prepare for certification exams, or finally audit that class on the history of rock and roll.

Free Math Resources, Lesson Plans, Games and Printables

I have been recently working on a small project to collect free math resources for some teachers in my area ( Halifax , Canada ) and what started as a small project ended up as a big research that took me up to a week which I hardly can afford out of my extremely busy schedule. Anyway I am glad it is finished and I am evern happier that several math teachers ( more than 30  ) who attended the workshop liked the materials provided.


math resources


Ironically enough, I am an English teacher and have nothing to do with math but still took the responsibility to run the workshop and provide the resources. I have read, re-read, reviewed and tested  numerous  links  and finally with the suggestions and help of Math  teachers, we selected 21 websites . I have included the websites in the presentation that you are going to see below.

The links included here are all educational websites where you can find evertyhting that is related to Math such as flashcards, games, puzzels, lesson plans, excersises and their solutions, interactive displays, diagrams and videos. I have also included the same presentation in three different version in Google docs, Issuu, and Slideshare, choose you feel comfortable with.
