Prepared Contributions for Discussion of Session III: Population Density and Crowding

Social Stimulus and Metabolism of the Brain
  • B. L. Welch


It is reasonable to assume that the endocrine effects of intensified social interaction that were discussed by the preceding speakers are mediated by the brain. For several years, A.S. Welch and I have been studying the effects of different levels of social stimulation upon brain norepinephrine, dopamine and serotonin, amines that are believed to have a primary role in the process of neurotransmission.
