The mechanism of action of these hormones is largely unknown although great strides have been made toward an understanding of how steroid hormones act on brain tissue. As a first step in illuminating the particular events underlying the hormonal mediation of behaviour, it is necessary t

More recently the contribution of circadian rhythms to the’organization of longer rhythms has been explored. We became interested in this general topic after reading the report of Hansen and Södersten of a diurnal rhythm in the levels of lord

Cholinergic Regulation of Feminine Sexual Behaviour in Laboratory Ratsinduce sexual responses through action at specific brain sites (Barfield and Chen 1977, Davis et al. 1979, Rubin and Barfield 1980). Cellular studies of steroid hormone action indicate that the hormone is translocated to the nucleus of the cell where it associates with the genome to allow “translati

ACTH and Grooming Behaviour in the Ratmists have isolated certain peptides from brain tissue, the studies on peptides and behaviour in fact were the first to demonstrate their important regulatory role in brain function. For instance, long before it was recognized that ACTH-like peptides could be found and synthesized in brain tissue, D

Genetic Determinants of Sexual Differentiationto show mating behaviours. The presence of functional testes during this perinatal period is correlated with the enhancement of masculine behaviours (masculinization) and the suppression of feminine behaviours (defeminization) while the absence of testes is correlated with the converse (Grady et al.
