that the basics of learning processes in the nerve cells are more
complex than hitherto assumed. (Photo: Morrison)
This “plasticity” of the brain, its ability to adapt physiologically
and structurally, is considered to be the foundation of learning. On
the basis of a complex computer simulation of 100,000 neurones with
10,000 contacts each – corresponding to about one cubic millimetre of
cortex - Abigail Morrison, Ad Aertsen and Markus Diesmann have
discovered that STDP may be insufficient to explain the learning
processes of nerve cells. The scientists’ results will be published in
the June issue of Neural Computation.
From earlier studies the researchers knew that their computer simulation reproduced many dynamic properties of the brain.
