Essay On Brain Plasticity

908 Words 4 Pages
When brain scientist talk about plasticity, they refer to the molding of organs circuit by new experiences building new writing patterns, pruning others. Brain plasticity or neural adaptation or neuro-plasticity is the ability of the CNS to change & adapt in response to environmental cues, experience, behaviour, injury or disease. Neuroplasticity is assumed to be one of the essential characteristics of the nervous tissue which may be manifested comparatively rapidly and result in reversible changes (functional plasticity). It may also modulate the expression of genotype into phenotype (adaptation) and thus bring about long-lasting effects. Neuroplastic mechanisms are triggered by various natural or artificial stimuli, which may arise in the

The resulting changes may occur in the communication between neurons (synaptic level), in the activity of local neuronal circuits (at the level of local circuits) or in the relations between individual functional brain systems (multimodular level). It may refers to changes in neural pathways and synapses which are due to changes in behaviour, environment and neural processes, as well as changes resulting from bodily injury(1). Neurons possess the ability to alter their structure and function in response to a variety of internal & external pressures, including behavioural training. Neuroscientific research indicates that experience can actually change both the brain's physical structure (anatomy) and functional organization (physiology). Brain plasticity is a physical process(2). Gray matter can actually shrink or thicken; neural connections can be forged and refined or weakened and severed. Often, people think of childhood and young adulthood as a time of brain growth but recent advance has shown the power of brain plasticity can help adult mind grow. The current review is basically looking at how the brain changes and rules governing these changes which are important for understanding both normal and abnormal
