Learning strategy trumps motivational level in determining learning-induced auditory cortical plasticity.
Associative memory for auditory-cued events involves specific plasticity in the primary auditory cortex (A1) that facilitates responses to tones which gain behavioral significance, by modifying representational parameters of sensory coding. Learning strategy, rather than the amount or content of learning, can determine this learning-induced cortical (high order) associative representational pla...
متن کاملLearning strategy determines auditory cortical plasticity.
Learning modifies the primary auditory cortex (A1) to emphasize the processing and representation of behaviorally relevant sounds. However, the factors that determine cortical plasticity are poorly understood. While the type and amount of learning are assumed to be important, the actual strategies used to solve learning problems might be critical. To investigate this possibility, we trained two...
متن کاملAuditory cortical plasticity in learning to discriminate modulation rate.
The discrimination of temporal information in acoustic inputs is a crucial aspect of auditory perception, yet very few studies have focused on auditory perceptual learning of timing properties and associated plasticity in adult auditory cortex. Here, we trained participants on a temporal discrimination task. The main task used a base stimulus (four tones separated by intervals of 200 ms) that h...
متن کاملPharmacological modulation of learning-induced plasticity in human auditory cortex.
PURPOSE Converging evidence from animals and humans indicate that the primary auditory cortex is continuously reshaped in an experience-dependent way. Reorganisation in primary auditory cortex can be observed at the level of receptive fields, topographic maps and brain activations measured with neuroimaging methods. Several neuromodulatory systems were shown to contribute to such an experience-...
متن کاملLearning-Induced Receptive Field Plasticity in the Primary Auditory Cortex
Primary sensory cortex in the adult is modified by learning. The primary auditory cortex is retuned when a tone is paired with a behaviorally relevant reinforcer. Frequency receptive fields are shifted toward or to the frequency of the signal stimulus, yielding enhanced processing and representation of important frequencies. Receptive field plasticity constitutes ‘‘physiological memory’’ becaus...
