circuitry

A variety of interesting articles concerning the neurobiology of neural networks. For example, one article by Gardner is "Static Determinants of Synaptic Strength". Although backpropagation as used in artificial neural networks is unlikely to be used by biological nervous systems, it is shown both in the buccal ganglia of Aplysia that synaptic strengths can be specified by postsynaptic neurons. As well, in the mammalian hippocampus, nitric oxide (NO) and arachidonic acid may serve as retrograde messengers from the postsynaptic cell for induction of long-term potentiation.
