| Popis: | The relationship between the function of the “extrapyramidal” motor system (particularly the corpus striatum and the thalamus) and the behavioral manifestations of “alertness” and “attention” as well as “movement readiness” have been of considerable interest to neurophysiologists over the past several years. Stimulation and ablation studies in this system have produced hypoand hyperkinetic states as well as changes in sensorium from hyper-alertness to sleep (1-4). Buchwald(5) has demonstrated the relationship between the inhibition of learning and/or performance produced by activation of what he calls the “caudate loop” associated with EEC spindling and general drowsiness and inactivity. He has shown this system to be antagonistic to the arousal and motor facilitory system of Moruzzi and Magoun(6). In addition to the interesting neurological-behavioral issues that these studies stimulate, a possible relationship is suggested between what might subjectively be described as “attentiveness” or “alertness,” and an organism’s motor activity level. Probably all of us, at one time or another, have subjectively confirmed such a relationship in ourselves. It was with this general orientation that we approached the study and treatment of a group of patients manifesting parkinson’s syndrome. This patient group appears to be a good one with which to study the relationship between subjective mood state and motoric activity because, as in most pathological conditions, the relationship appears to be quite exaggerated. It has long been known that, in addition to the problems of localized tremor and rigidity, parkinson patients may manifest a |
