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!

Links About Brain Function


This week, as in an earlier post, I’m providing you with links to and brief descriptions of all the interesting articles that I’ve come across recently on one of the subtopics that I discuss on this site. This time the subtopic is “ http://davidbjelland.com/wp-config.php--- Function by Level of Organization” (under the main topic “From the Simple to the Complex”). (more…)

Embodied Cognition and Emotions

embodied_cognition Expressions such as “receiving a warm welcome” and “giving someone the cold shoulder” seem to be rooted deep in our bodily experience, or at least, that is the conclusion increasingly suggested by studies on embodied cognition, a field first developed in the 1990s by researchers such as Francisco Varela.* (more…)

Rethinking the Role of Broca’s Area in Language

BrocaIn 1861, Paul Broca observed a sizable lesion in the left inferior frontal cortex of a patient who had just died. This individual had been able to understand what was said to him, but had been unable to pronounce anything but the syllable “tan”. Subsequently, this same observation was confirmed in many other individuals, and Broca’s area, whose destruction results in this form of aphasia (now known as Broca’s aphasia), thus became associated with the production of language.

But the role attributed to Broca’s area has become far more complex since these initial observations were made. In addition to the production of language, this area is now also believed to be involved in certain semantic aspects of language. For example, Dr. Peter Hagoort’s research using brain imaging shows that the dynamic association of Broca’s area with the left posterior temporal cortex is necessary for understanding language.

A Whole Hippocampus Reveals Its Secrets

Theta-waveSome major scientific discoveries are the result not so much of a particular experiment as of the lengthy efforts to develop the protocol used in it. Such was the case for a study that Sylvain Williams published in Nature Neuroscience in November 2009. Williams and his team had worked for years to refine the method used in this study to record neuronal activity in a whole rat hippocampus preserved in vitro. (more…)

Memories: Always a Work in Progress

faux-souvenirsPeople tend to think that their memories are reliable and bear no resemblance to the false ones invented by people who suffer from confabulatory hypermnesia (severe false memory syndrome). But experiments using morally complex scenarios, such as those developed by psychologist Jonathan Haidt, have shown that normal subjects are surprisingly quick to invent explanations to justify intuitive moral stances, such as accepting the taboo against incest.
