Document Summary
Neuroplasticity is the ability of the nervous system to undergo changes in its anatomical, chemical, and physiological/functional properties. Why this is of interest: behavioural changes (how the brain influences these changes), how people regain function after brain damage, Ramon y cajal: expressed strong doubts regarding the ability of the cns to express. Hebb: examined the influence of environment and on behaviour and intelligence ; brains are shaped by experience they are plastic. Is a learning mechanism inhibitory avoidance learning. Evidence that ltp is a synaptic memory mechanism: Learning a task can elicit ltp in the brain. It offers a model to study the synaptic, cellular, and molecular basis of neural plasticity and memory formation. Plasticity during brain development and aging: critical/sensitive period specific temporal windows od heightened neuronal plasticity, followed by greater resistance to change, the young brain is more plastic than an older brain.
