Document Summary
Neuroplasticity part 2: the physiological basis of motor learning. How injury-induced plasticity and recovery of function. Mechanisms of underlying recovery of function following injury. Ramon y cajal (the father of neuroscience)- suggested that growth was not possible in neurons in the adult cns. When development was completed, the growth and regeneration of axons and dendrites was lost (1928) This view persisted until the late 1960"s and 1970"s. Researchers began to discover growth and reorganization of neurons in the adult cns after injury. One of the first events following nervous system injury. Loss of function in a structurally intact brain area due to loss of input from anatomically. Accumulation of intracellular fluid, or leakage of proteins or fluid from blood vessels. May lead to compression of axons and physiological blocking of neuronal conduction. Reflects the formation and regeneration of synapses (synaptogenesis) Occur when neurons show loss of input from another brain region. The postsynaptic membrane becomes hyperactive to released transmitter substance.
