After providing all the funding for The Brain from Top to Bottom for over 10 years, the CIHR Institute of Neurosciences, Mental Health and Addiction informed us that because of budget cuts, they were going to be forced to stop sponsoring us as of March 31st, 2013.

We have approached a number of organizations, all of which have recognized the value of our work. But we have not managed to find the funding we need. We must therefore ask our readers for donations so that we can continue updating and adding new content to The Brain from Top to Bottom web site and blog.

Please, rest assured that we are doing our utmost to continue our mission of providing the general public with the best possible information about the brain and neuroscience in the original spirit of the Internet: the desire to share information free of charge and with no adverstising.

Whether your support is moral, financial, or both, thank you from the bottom of our hearts!

How Poverty Harms the Brain

childrenThe brain is highly sensitive to the environment in which it develops, especially during childhood. Since the experiments conducted in the 1960s with rats raised in environments rich in sensory and social stimulation, there is no longer any doubt that an enriched environment promotes brain development, whereas an impoverished environment slows it down.

Regarding humans, there have been countless studies showing that low socio-economic status, usually associated with a poor environment, alters functions such as attention, working memory, language, and self-control. Beyond these, there are the overall harmful effects of social inequality on health. In Montreal, Quebec, for example, life expectancies are 10 years lower in poor neighbourhoods than in rich ones.

Do we synchronize our neurons to synchronize our thoughts?

oldradioJust as the pendulum of a clock oscillates to keep the time, the human brain’s networks of neurons oscillate together to help us encode certain memories. Or at least that is one of the functions attributed to these neuronal oscillations, which have been largely preserved throughout the history of evolution in the animal kingdom. Researchers are taking a growing interest in these oscillations, because if they do let the brain encode information in terms of time, they represent a valuable tool in addition to the mechanisms by which the brain generates its many spatial representations of the body and the world outside it.

Genes to Cognition Online

There are not too many web sites about the human brain that are structured according to the human organism’s levels of organization, so that readers always keep this fundamental concept in mind. That is understandable, given the all the extra work involved in writing the content for such a site. But a handful of writers have been energetic enough, or foolish enough, to attempt this approach, including yours truly, with The Brain from Top to Bottom.

Because web sites like mine are so scarce, I would feel remiss if I did not let my readers know about another one that has been around for a few years now. It is called Genes to Cognition Online (first link below). (more…)

Our Mirror Neurons Prefer the Movements We’ve Already Learned

Often I use this blog to talk about the latest studies in neuroscience. But this week I want to talk about a study that was conducted a few years back, because it provides a good introduction to the brain cells known as mirror neurons, which are often described as strange entities indeed.

Mirror neurons were first identified in the motor area of the frontal cortex of monkeys, by Italian neurophysiologist Giacomo Rizzolatti, in the early 1990s. Rizzolatti discovered that these particular neurons became activated not only when monkeys made a hand gesture or a facial expression (as is normal for motor neurons), but also when monkeys watched other monkeys doing so, without making the gesture or expression themselves (hence the name “mirror neurons”).
