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!

The interactions between DNA and proteins

This week, I’d like to say a few words about an important change from the way that the interactions between DNA and proteins were long thought of.

We have now come a long way from the simplistic linear understanding that we had from the start of genetics, in which the “genetic program” of DNA was copied into messenger RNA which then exited the cell nucleus and was translated into proteins in the cytoplasm. As we have just seen, the reality is more of a complex metabolic network subject to a circular logic that assumes no “program” and hence no absolute starting point. In other words, we must now discard this “genocentric” heritage according to which DNA is the foundation of everything, because it provides the building plans. (more…)

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…)
