GABAergic microcircuits in the neostriatum.
The vast majority of neostriatal neurons and intrinsic intrastriatal synapses are GABAergic, the latter arising from axon collaterals of spiny projection neurons and from GABAergic interneurons. An important feature of the functional organization of the neostriatum has long been assumed to be the existence of a widespread lateral inhibitory network mediated by the axon collaterals of spiny proj...
متن کاملThe Electromyographic Feedback and Feedforward Activity of Selected Lower Extremity Muscles During Toe-in Landing in Female Athletes
Background: Positioning the legs in performing spike technique significantly contributes to the development and prevention of lower limb injuries. The present study aimed to evaluate and compare the feedback and feedforward activaties of selected lower limb muscles during triple jump spike with and without toe-in landing in female volleyball players. Methods: In this controlled-laboratory stud...
متن کاملGenetic Feedforward-Feedback Controller for Functional Electrical Stimulation Control of Elbow Joint Angle
Background: Functional electrical stimulation (FES) is the most commonly used system for restoring functions after spinal cord injury (SCI). Objective: In this study we investigated feedback PID and feedforward-feedback P-PID controllers for regulating the elbow joint angle. Methods: The controllers were tuned based on a nonlinear muculoskeletal model containing two links, one joint with one de...
متن کاملPresynaptic modulation by somatostatin in the rat neostriatum is altered in a model of parkinsonism.
Somatostatin (SST) is a peptide synthesized and released by a class of neostriatal local GABAergic interneurons, which, to some extent, are in charge of the feedforward inhibitory circuit. Spiny projection neurons (SPNs) make synapses with each other via their local axon collaterals, shaping the feedback inhibitory circuit. Both inhibitory circuits, feedforward and feedback, are related through...
متن کاملStriatal Cell Types and Their Interaction
The neostriatum is strategically located in the forebrain and receives inputs from all cortical areas. The complexity of the corticostriatal pathways suggests that striatal neurons are in a unique position to process convergent inputs from cortex and through basal ganglia output nuclei to control subcortical nuclei and/or contribute to cortical dynamics via the thalamus. The most abundant neuro...
