Modulation of neuronal activity in the monkey putamen associated with changes in the habitual order of sequential movements.

Sequential cellular changes produced by african horse sickness virus in monkey kidney cells

Neuronal activity in the striatum and pallidum of primates related to the execution of externally cued reaching movements.

We studied changes in basal ganglia neuronal activity associated with reaching movements of the arm in two monkeys. Data were obtained from 427 single neuronal units in putamen, 199 in caudate nucleus, and 216 in globus pallidus with multiwire electrodes allowing simultaneous recordings from multiple neurons. In all structures, changes in activity related to movement occurred most often after t...

The role of muscarnic cholinergic receptor of the bed nucleus of stria terminalis on cardiovascular response and baroreflex modulation in rat.

Introduction: The bed nucleus of the stria terminalis (BST) is a limbic structure which is involved in cardiovascular regulation and baroreflex modulation. The presence of cholinergic synaptic terminalis with high level of muscarinic receptors in the BST has been demonstrated. This study was performed to find the role of the cholinergic muscarinic receptor in cardiovascular response and baro...

Movement-related neuronal activity selectively coding either direction or muscle pattern in three motor areas of the monkey.

1. Movement-related neuronal activity in the supplementary motor area (SMA), primary motor cortex (MC), and putamen was studied in monkeys performing a visuomotor tracking task designed to determine 1) the extent to which neuronal activity in each of these areas represented the direction of visually guided arm movements versus the pattern of muscle activity required to achieve those movements a...

Delayed Synaptic Changes in Axotomized Spinal Motoneurons of Newborn Rats Associated with Progressive Neuronal Loss: Immunohistochemical, Ultrastructural, and Quantitative Study

Background and Objective: Sciatic nerve transection is characterized by a rapid wave of motoneuron death associated with progressive synaptic lesions. The purpose of this study was to evaluate the long term synaptic changes. Materials and Methods: This basic study was carried out on paraffin- or resin-em...
