I have questions in my mind about the currently popular research into quantum non-locality in neural systems. However, I do know of mechanisms by which a few synapses with patterned releases of neurotransmitter can control the dynamics of a dendrite (Barlett Mel's work), a couple of basal dendrites can cooperate to control the dynamics of a neuron (preliminary modeling work), and perhaps 500 principle cells in a nerve cell assembly can control the spiking of 10,000-40,000 neurons. These seem to involve (at least in the latter two cases) stochastic resonance in an actively tuned system. Once at the level of 10,000-40,000 neurons, the next few stages up (leading to the entire brain) are currently the subject of active research. So it seems the turtles do extend down to the synapse. Has there been any study of structured dynamics within the synapse? -- Harry Erwin Internet: herwin@gmu.edu Just a dumb graduate student working on Katchalsky network models....
