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!

Dusting Off the Triune Brain and the Limbic System

In neuroscience, as in other fields, some concepts are so convenient that it no longer even occurs to us to question them. But no scientific knowledge can be taken for granted forever, so it makes sense to take such old concepts down from the shelf and dust them off from time to time.

Recently, two neuroanatomists, Pierre-Yves Risold and Helmut Wicht, did just that with two models—the “triune brain” and the “limbic system”—that have become questionable, to say the least, in light of more recent neuroanatomical findings. (more…)

Optogenetics: Neurons Controlled by Light

Among the many new techniques developed in the neurosciences in recent years, few have caused as much of a stir as optogenetics. This strange marriage between the sciences of optics and genetics allows the activity of entire populations of neurons in the brains of living animals to be controlled with a simple ray of light. Just a decade or two ago, such a technique, which is relatively non-invasive and accurate to within one millisecond, would have been unimaginable! (more…)

Learning How To Pique Curiosity

?

What is learning? What teaching methods are the most effective? Under what conditions do we remember information best? These are big questions, and the subject of continuing debate.

 

Neuroscientists continue to contribute relevant data to this debate, in particular as regards the conditions that help us learn and retain information best. In 2009, Min Jeong Kang’s research team published a brain imaging study that confirmed the importance of a well known but often under-utilized condition for enhancing learning: curiosity. (more…)

Like Strangers in Their Own Land

Fewer than 100 cases of foreign accent syndrome, have been identified worldwide, but it is certainly one of the strangest things that can happen to anyone. From one day to the next, a person wakes up speaking with what sounds like an accent from another country.

But in fact, this similarity is merely random. Scientists now know that foreign accent syndrome is actually a particular kind of aphasia that produces slight alterations in the  prosody of language. Listeners then perceive these unusual variations in the rhythm and meolody of the person’s speech as a foreign accent. (more…)
