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!

Neurons with Surprising Properties

Just when scientists thought they had a pretty good understanding of how neurons communicate, along comes a new set of seemingly abnormal data that overturn the official paradigm (such upheavals are not uncommon in the world of science). Any good neuroscience textbook will tell you that neurons are stimulated or inhibited by input signals that they receive through the synapses between their dendrites or cell bodies and other neurons. As a neuron receives all these signals, it integrates them, and then fires one or more action potentials into its axon. These action potentials travel down to the tip of the axon, where they cross synapses to other neurons, and so on.

But as a team of researchers from Northwestern University, in Illinois in the United States, discovered and reported in the February 2011 issue of Nature Neuroscience, the process just described is clearly not the only way that nerve impulses travel through neurons. (more…)
