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!

Brain Rhythms: The Oscillations That Bind

Most of the neurons in the human brain emit nerve impulses (also known as action potentials) at a specific frequency, which may vary from just a few per second to several hundred per second. The chaotic brain activity revealed by an electroencephalogram (EEG) reflects the summing of all these oscillations in the billions of neurons in the brain.

Not so long ago in the history of neuroscience, the chaotic nature of all these oscillations caused them to be regarded as background noise and given little attention, or even dismissed as an epiphenomenon of no importance. But times have changed. The temporal dimension of brain activity, as expressed by these brain rhythms, is now central to neuroscientific research on complex topics such as sleep and consciousness.
