The Brain Reshapes Our Malleable Senses to Fit the World

March 24, 2020

How does experience alter our perceptions? This adapted book excerpt from We Know It When We See It describes how the brain’s visual system rewires itself to make the best use of its neural resources.

Hidden Computational Power Found in the Arms of Neurons

January 14, 2020

The dendritic arms of some human neurons can perform logic operations that once seemed to require whole neural networks.

A brain full of “explosive” activity may lead to an earlier death than one with steadier “candles” of activity.
