Eccles hypothesized that the immaterial Self can effectively control the brain through intentions and attentions. Neural responses are induced by mental action by increasing the quantum probability of exocytosis, or the release, of the contents of synaptic vesicles from presynaptic vesicular grids (PVG). The vesicular contents are neurotransmitters that are released into and across very narrow synaptic clefts, a process that has been observed by electron microscopy. Their release is from the opened pores of vesicles that are docked on the PVG and occurs in a semantically integrated fashion within neural networks associated with specified intentional thoughts and actions. Their release stimulates adjacent postsynaptic densities of neurons to induce action potentials that are transmitted as encoded spike trains that the immaterial mind interprets through a process of lifelong learning archived in memory. These induced spike train impulses are transmitted downstream along the axonal efferent pathways of synaptic networks in coherent, synchronized fashion in terms of wave frequencies, amplitudes and shapes. In Part Two of my blog entitled “Waves in Our Brains” this activity is discussed in detail. It is a complex process, but neuroscientists are gaining increasing understanding of it.
