Siderosis of the Globus Pallidus in a Monkey.
THE following case is reported as a contribution to the records of comparative pathology. In the course of examining a brain of an apparently normal mangabey monkey (Cercocebus torquatus atys), deposits were observed in the globus pallidus of both sides accompanied by rarefactions of the surrounding nervous tissue. The monkey, O.M.487, a four year old male with a body-weight of 5,200 gms., had ...
متن کاملActivity of neurons in monkey globus pallidus during oculomotor
29 The basal ganglia are a subcortical assembly of nuclei involved in many aspects of 30 behavior. Three of the nuclei have high firing rates and inhibitory influences: the 31 substantia nigra pars reticulata (SNr), globus pallidus interna (GPi), and globus pallidus 32 externa (GPe). The SNr contains a wide range of visual, cognitive, and motor signals that 33 have been shown to contribute to s...
متن کاملImpaired reaching and grasping after focal inactivation of globus pallidus pars interna in the monkey.
The purpose of this study was to test the hypothesis that the basal ganglia output from globus pallidus pars interna (GPi) contributes to inhibition of competing motor patterns to prevent them from interfering with a volitional movement. To test this hypothesis, the kinematics of a natural reach, grasp, and retrieval task were measured in the monkey before and after focal inactivation in GPi wi...
متن کاملAnaesthesia for thermocoagulation of the globus pallidus.
Stage I. Stereotaxic radiological localization of the globus pallidus. The position of the globus pallidus is calculated from radiographs taken after lumbar air encephalography. For this procedure the patient is placed in the sitting position. A graduated metal frame is secured to the head by three drills penetrating the outer plate of the skull. Air is injected into the ventricular system by l...
متن کاملDichotomous Organization of the External Globus Pallidus
Different striatal projection neurons are the origin of a dual organization essential for basal ganglia function. We have defined an analogous division of labor in the external globus pallidus (GPe) of Parkinsonian rats, showing that the distinct temporal activities of two populations of GPe neuron in vivo are underpinned by distinct molecular profiles and axonal connectivities. A first populat...
