The Hippocampus as a Cognitive Map: The Book

A few weeks ago the Nobel Prize Committee announced that John O’Keefe, Edvard Moser and May-Britt Moser would be the recipients of the 2014 prize for Physiology and Medicine for their work in deciphering the neural code in the rat hippocampal region.1 The work is frequently summarized as revealing the functioning of the brain’s GPS system.  While the GPS part is true, the work is far broader, giving insights into the neural substrate of broad areas of cognition that include memory, planning, creativity and internal thought.

The Brain’s White Matter–Learning beyond Synapses

Recently scientists have been exploring part of the brain that has been relatively unexplored in learning–white matter, comprising half of the human brain.  Here new research is detecting cellular changes during learning that are entirely different from the synaptic changes between neurons in gray matter.  A new study shows that learning a new motor skill requires generation of new myelin, the electrical insulation on nerve axons.

Wipe Out Fearful Memories

I’ll never forget it.  They strapped electrodes to my wrist, cranked up a black dial on a frightening electronic device encrusted with switches and knobs, and shocked me repeatedly with jolts of electricity.  Continue reading
