Statistical context shapes stimulus-specific adaptation in human auditory cortex.
Stimulus-specific adaptation is the phenomenon whereby neural response magnitude decreases with repeated stimulation. Inconsistencies between recent nonhuman animal recordings and computational modeling suggest dynamic influences on stimulus-specific adaptation. The present human electroencephalography (EEG) study investigates the potential role of statistical context in dynamically modulating ...
متن کاملAcross-ear stimulus-specific adaptation in the auditory cortex
The ability to detect unexpected or deviant events in natural scenes is critical for survival. In the auditory system, neurons from the midbrain to cortex adapt quickly to repeated stimuli but this adaptation does not fully generalize to other rare stimuli, a phenomenon called stimulus-specific adaptation (SSA). Most studies of SSA were conducted with pure tones of different frequencies, and it...
متن کاملStimulus-specific Adaptation in Auditory Thalamus of Young and Aged
20 Novel stimulus detection by single neurons in the auditory system, known as stimulus-specific 21 adaptation (SSA), appears to function as a real-time filtering/gating mechanism in processing 22 acoustic information. Particular stimulus paradigms allowing for quantification of a neuron’s 23 ability to detect novel or deviant stimuli have been used to examine SSA in the inferior 24 colliculus,...
متن کاملStimulus-Specific Adaptation and Deviance Detection in the Rat Auditory Cortex
Stimulus-specific adaptation (SSA) is the specific decrease in the response to a frequent ('standard') stimulus, which does not generalize, or generalizes only partially, to another, rare stimulus ('deviant'). Stimulus-specific adaptation could result simply from the depression of the responses to the standard. Alternatively, there may be an increase in the responses to the deviant stimulus due...
متن کاملStimulus-specific adaptation occurs in the auditory thalamus.
Neurons in the primary auditory cortex respond less strongly to a commonly occurring "standard" tone than to the same tone when it is rare or "deviant." This phenomenon, called "stimulus-specific adaptation" (SSA), has been proposed as a possible single-neuron correlate of the mismatch negativity, a cortical evoked potential associated with stimulus novelty. Previous studies in cat did not obse...
