A mechanism predicted theoretically by a Coneural scientist has been found
experimentally in the brain
September 20, 2007
An international team of scientists, led by Alfredo Kirkwood from Johns Hopkins
University (USA) found that, in the visual cortex, neuromodulators control
the polarity of spike-timing-dependent synaptic plasticity (Neuron,
vol. 55, pp. 919-929, September 2007). Such a phenomenon has been predicted
by Coneural's Razvan Florian, who has shown analytically and through computer
simulations that such a modulation leads to reinforcement learning
(Neural
Computation 19 , pp. 1468-1502, June 2007).
