Components of Mating

Kollack-Walker & Newman (1997)

• Results:

  • significant patterns of activation were observed within medial amygdala (MeA), bed nucleus of the stria terminalis (BNST) and medial preoptic area (MPOA) following: FHVS exposure alone, mating to 1 ejaculation, and mating to multiple ejaculations
  • in particular, neuronal cell “clusters” in the caudal part of the posterior medial nucleus of the amygdala (cMePD) were seen in 67% of males mating to 5 ejaculations, and in 100% of males mating to long intromissions

• Conclusion:

  • different patterns of c-fos expression were observed in males that engaged in different levels of sexual activity (chemoinvestigation, copulation)

• Question: Does the selective pattern of neuronal activation seen following multiple ejaculations reflect a state of satiety or simply a phenomonon of experiencing multiple ejaculations?
