Paran neurons suggest a continuum of adaptation between central nervous system neurons and peripheral neuroepithelial/neuroendocrine cells, allowing external information processing to guide behavior.

“there was not such a discrete distinction between an entire a neuron that lives inside of the brain or the central nervous system and a A neuroepithelial or a neuroendocrine cell that leaves exposed to the outside simply that there is a continuum of adaptation so the the organism can bring the information from outside inside into the uh body to be able to process it and then process it and then guide Behavior”
