UTERINE MOTILITY OF THE ESTROGENIZED RABBIT. V. RESPONSE TO BRAIN STIMULATION,
Abstract
Uterine contractions were elicited by electrical stimulation of points located in the lateral parts of the medulla oblongata, whereas inhibitory responses were induced from the midline medullary region. Cerebellar stimulation determined an inhibition of the rhythmic uterine activity followed by a rebound effect, on cessation of the stimulation. From the hypothalamus three different responses were obtained: (i) excitatory effects from the perifornical, the dorsal, lateral and posterior hypothalamic areas due to sympathetic activation, (ii) uterine excitation by oxytocin liberation induced from the ventromedial part of the hypothalamus, and (iii) inhibition of the uterine rhythmic activity by stimulation of a restricted region in the lateral hypothalamic area. Excitatory responses were also evoked from the amygdala, from sensorimotor cortex, and the anterior limbic region. Inhibitory uterine responses were produced from the two cortical areas just mentioned as well as from the orbital surface. (Author)
