Another interesting fact is that lesions in the primary visual cortex cause
amaurosis corticalis - a condition with decreased visual acuity or even blindness,
but with normal pupillar reactions i.e. although there is subcortical neural
processing of information, it is not realized because it does not enter the cortex. It
can also be concluded that relevant stimulus for the cortical neural cells is the
membrane potential, which is then converted into specific quantum states if the
Q-mind hypothesis proves true!
Neuronal morphology
The morphology of a single neuron is relatively simple. In this study is presented
a hippocampal pyramidal CA3 (cornu ammonis 3 region) neuron that is typical
cortical pyramidal neuron. The neuron has body called soma and two types of
projections: dendrites that input electrophysiologic information and axon
branching into axonal collaterals that output information via neuromediator
release (exocytosis) under membrane firing (depolarization).
