Fifty Years Ago Donald Hebb Proposed a Rule

The Hebb Rule says that if an initially weak synapse repeatedly fires at the same time that the postsynaptic neuron fires, the synapse will become strengthened. After several firings, the synapse becomes strong enough to fire by itself. LEARNING HAS OCCURRED.

Hebb was unable to determine if this was right or wrong. Can you imagine the suspense?

Learning is happening all over the place right now, in fact. Five chapters left plus twelve cranial nerves (and their functions). My dysfunctional dalliance in biopsychology officially ends tomorrow at 3pm. I can be drunk by 4, removing most residual knowledge with the destruction of a few million brain cells. Hey, math major: with 16 upper division credits, how much tuition is lost from the consumption of one twelve-dollar bottle of rum?

The economics of that plan aren't looking good...
