Motor areas of the cerebral cortex.
The motor cortex includes several areas in the frontal agranular cortex. These areas receive inputs from sensory pathways, motor control structures, other cortical areas, and from "modulatory" pathways. Motor cortical outputs are widely distributed to many other parts of the nervous system and can thereby influence each of the major descending motor control pathways and spinal motor circuitry. ...
متن کاملCellular physiology of the neonatal rat cerebral cortex.
The early development of the cerebral cortex is characterized by neurogenesis, neuronal migration, cellular differentiation and programmed cell death. Cajal-Retzius cells, developing cortical plate neurons and subplate cells form a transient synaptic circuit which may serve as a template for the formation of cortical layers and columns. These three neuronal cell types show distinct electrophysi...
متن کاملCerebral Palsy: Motor Types, Gross Motor Function and Associated Disorders
Objectives: Cerebral palsy (CP) describes a group of disorders in the development of movement and posture in the developing brain. The main aim of this study was to determine the distribution of motor impairment and associated disorders in a population of children with CP. Methods: This study was carried out in 2011 during three months, on 200 CP children. Multiple sources of ascertainment w...
متن کاملStereological study of the cerebral and cerebellar cortex following short time exposure to morphine in rats
Drug abuse has been claimed to cause the loss of neurons and reduction of volume in both the adult and developing brain. This study examined cortex volumes in cerebrum and cerebellum of male rats that were dependent on morphine using unbiased stereological counting methods and systematic random sampling technique. Our goal was to test whether short time exposure to morphine can affect the corte...
متن کاملEffect of paraoxon on the synaptosomal GABA uptake in rat hippocampus and cerebral cortex
Introduction: Paraoxon (the neurotoxic metabolite of organophosphorus (OP) insecticide, parathion) exerts acute toxicity by inhibition of acetylcholinesterase (AChE), leading to the accumulation of acetylcholine in cholinergic synapses and hence overstimulation of the cholinergic system. Since, reports on changes in the level of γ- amino butyric acid (GABA) during OP-induced convulsion have bee...
