Blood pressure rises and reaches a peak during the late plateau stage just prior to orgasm. Sometimes, involuntary contractions of the hands and feet occur (called carpopedal spasm), causing the toes to curl up or the hands to close. As evidence against the local theories accumulated, emphasis shifted to central receptors in the brain that monitor conditions such as blood glucose or blood osmolarity, which might trigger appropriate motivational states. One current proposal looks at the interaction of peripheral cues such as leptin (a hormone produced by fat cells) and central receptor sites in the hypothalamus that together help to regulate eating behavior. The activating property of motivation, or activation, is most easily seen in the production of behavior. If it is, then at least some minimal amount of motivation is assumed to be present. If no overt behavior is observed, then the motivational level of the.
