Learning & the Hebbian Synapse
- Physiological learning
- Pavlov concept of classical conditioning
- led to Lashley search for connections
in cerebral cortex
- also stimulated Hebb to
propose mechanism for
change at a synapse
- an axon that has successfully stimulated
cell B in the past becomes even more
successful in the future.
- A synapse that increases effectiveness because
of simultaneous activity in presynaptic and
postsynaptic neurones called Hebbian Synapse
- In development of visual system
if axon from left eye fires at same
time as one from right eye
- neuron in visual cortex increases response to both of them
- such synapses may also
be critical for many kinds of
associative learning
- Neuroscientists have discovered
much about mechanisms of
Hebbian Synapses.
