Sweat has been the focus of research on human pheromones, and in fact, male underarm sweat has been shown to women mood mood and affect their secretion of luteinizing hormone, which is normally involved in stimulating ovulation. Other studies have shown that is used in female sweat on the upper lip of other women, these women by synchronously their menstrual cycles direction with the cycle of the woman.
Respond to the sweat got.Androstadienone, a derivative of testosterone in high concentration in high concentration in male sweat, and in all other body exudates has garnered the most attention. But although suspect its effect on a woman ‘s mood, physiological arousal and brain activity chemical is chemical is possible pheromone-like signal in humans , its effect on hormone levels was unknown.* The thesis was on the 10th January 2007* Supervisor Prof. Cl defend de Zeeuw* Associate Supervisor Dr Ruigrok.. By injecting a viral tracers agents in several muscle, the explorer tracked that cerebellar modules involved the control of single muscles. Will one module deactivated by the injection of a neurotoxin. The rats walking ability has been little change but there been a big drop in its ability to doctor father Prof. To remove obstacles in a reflexive way This showed that certain modules that especially regulating reflection functions whilst walking and tailor them to the situation.
In his ability to the cerebellum obtain two types of signals. Through the climbers fibers, signals of of a specific structure the brain stem about Purkinje cells are transferred is in the cerebellum. Moss fibers transmission signals of different parts the central nervous system with the granule cells the cerebellum.. Pijpers and their counterparts investigation of which processes took both inside and outside of cerebellum: As duct does that information and process management at signal to muscles? Then they investigated which part of the cerebellum are involved in in the regulation of activity of an individual muscle. They also studied the effects of inactivating one or more parts the cerebellum to the functioning of this muscle.
