Auditory associative memory and representational plasticity in the primary auditory cortex.
Historically, the primary auditory cortex has been largely ignored as a substrate of auditory memory, perhaps because studies of associative learning could not reveal the plasticity of receptive fields (RFs). The use of a unified experimental design, in which RFs are obtained before and after standard training (e.g., classical and instrumental conditioning) revealed associative representational...
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...
متن کاملPhysiological memory in primary auditory cortex: characteristics and mechanisms.
"Physiological memory" is enduring neuronal change sufficiently specific to represent learned information. It transcends both sensory traces that are detailed but transient and long-term physiological plasticities that are insufficiently specific to actually represent cardinal details of an experience. The specificity of most physiological plasticities has not been comprehensively studied. We a...
متن کاملThe Effectiveness of Group Play Therapy on Social Skills and Memory Performance of primary school girl student’s with Specific learning disorder
Introduction: Learning disorders is one of the important factors in the academic failure of some students and determining appropriate therapeutic methods can solve their educational problems and increase their sense of self-esteem. Therefore, the purpose of present study was to investigate the effectiveness of group play therapy on social skillsand memory performance of Primary school girl stud...
متن کاملAssociation learning-dependent increases in acetylcholine release in the rat auditory cortex during auditory classical conditioning.
The cholinergic system has been implicated in sensory cortical plasticity, learning and memory. This experiment determined the relationship between the acquisition of a Pavlovian conditioned approach response (CR) to an auditory conditioned stimulus (CS) and the release of acetylcholine (ACh) in the primary auditory cortex in rats. Samples of ACh were collected via microdialysis during behavior...
