What is a "Hebb synapse," and how does this concept help us understand the segregation between input from each eye in the lateral geniculate nucleus of the adult animal?
What will be an ideal response?
Hebb is the scientist who first postulated that there are changes in the physical structure of a synapse that occur with use. The more synaptic signaling across a synapse, the larger the synapse grows and more neurotransmitter it releases, and onto more post-synaptic receptors. Studies have shown this is how systems develop, where use of a pathway strengthens that pathway.
