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!

Two “Trees of Life”

Protect Your Immune System by Refusing To Be Dominated!

A study published in the November 25, 2016 issue of the journal Science shows that subordinate status in a social group seems to have harmful effects on an individual’s immune system. More specifically, this study found that a female rhesus monkey’s relative position in her group’s dominance hierarchy influenced the functioning of her immune system in the following way: the lower her rank, the fewer immune cells of a certain type her body produced.

And such differences seem to be caused by the activation or non-activation of certain genes. The study’s authors found that when they used experimental manipulations of the group to change individuals’ ranks in the hierarchy, the rate of expression of these genes changed as well. (more…)
