Document Summary
Acoustic startle reflex defensive response to a loud, unexpected noise. Sensory prosthesis that directly stimulates auditory nerves to produce hearing sensations in deaf individuals. Proposes that the changes in responses to repeated events are a consequence of the gradual construction of neural representations of stimuli and the context in which they occur. A motor rehabilitation technique in which unaffected limbs are restrained to increase usage of dysfunctional limbs. The capacity for cortical receptive fields and cortical spatial organization to change as a result of experience. Representations of stimuli initially are formed rapidly and vaguely but become more precise over time by incorporating further details as the stimulus is repeated. Discrimination training training an individual to respond differently to different stimuli. Assumes that the brain is limited in how much information it can collect in a single exposure to a novel stimulus.
