A prefix denoting "known or mediated by the nervous system ." Since all human knowledge is neurological in this sense, every science may be considered a neuro-science; e.g., we have no physics but neurophysics, no psychology but neuropsychology and ultimately, no neurology but neuroneurology. But neuroneurology would itself be known by the nervous system, leading to neuroneuroneurology etc., in an infinate regress. See Von Neumann's Catastrophe [Illuminati Papers, 1980
