Resumo(s)
"This monograph is composed of five Chapters. Chapter 1 consists of a
general introduction, where the relevant literature for this project is
discussed. We start by generally describing sexual behaviour importance
in several areas and then evolve to describing copulation in mammals and
rodents. We highlight the differences in the copulatory sequence between
rats and mice and why these differences may readout in distinct neuronal
pathways. We describe said neuronal circuits, spanning from the brain
control of sexual behaviour to the spinal control of ejaculation and the
seminal papers in the rat describing a spinal ejaculation generator
composed by a group of Gal+ cells that control the BSM-MNs. We end by
depicting the peripheral nervous system role in the control of the pelvic
organs and how it impinges on the spinal circuit responsible for controlling
ejaculation and sexual behaviour.(...)"
