Olfactory Reactions in the Dentate Gyrus and Pyriform Cortex

  • C. H. Vanderwolf


By the winter of 1990–91 I began to feel that I had worked long enough on hippocampal rhythmical slow activity and neocortical activation. It seemed to me to be fairly well established that these electrographic reactions were dependent on ascending cholinergic and serotonergic inputs and were related to the cerebral control of behavior but could not be understood in terms of conventional psychological concepts.

    The fact that there were only one or two informal complaints is an eloquent testimonial to the tolerance displayed by my colleagues and their students and technicians.Google Scholar
