Stop Saying the Brain Learns By Rewiring Itself
Most neuroscientists believe that the brain learns by rewiring itself—by changing the strength of connections between brain cells, or neurons. But experimental results published a few years ago, from a lab at Lund University in Sweden, hint that we need to change our approach. They suggest the brain learns in a way more analogous to that of a computer: It encodes information into molecules inside neurons and reads out that information for use in computational operations.
With a computer scientist, Adam King, I co-authored We argued that well-established results in cognitive science and computer science imply that computation in the brain must resemble computation in a computer in just this way. So, of course, I am fascinated by these results.
