GABAergic mechanisms involved in the prepulse inhibition of auditory evoked cortical responses in humans
Despite their essential roles in signal processing in the brain, the functions of interneurons currently remain unclear in humans. We recently developed a method using the prepulse inhibition of sensory evoked cortical responses for functional measurements of interneurons. When a sensory feature is abruptly changed in a continuous sensory stimulus, change-related cortical responses are recorded...
متن کاملPrepulse inhibition of change-related P50m no correlation with P50m gating
Both prepulse inhibition (PPI) of the startle response and P50 sensory gating are important tools to investigate the inhibitory mechanisms of sensory processing. However, previous studies found no or a weak association between these two measures, which may have been due to the different indexes used. We examined the relationship between P50 sensory gating and P50 PPI. P50m sensory gating and PP...
متن کاملPrepulse-elicited startle in prepulse inhibition.
BACKGROUND Prepulse inhibition (PPI) has become a major experimental paradigm in the study of psychiatric disorders. In this study, a potential confound in measurement and interpretation of PPI, namely startle reactions to so-called "nonstartling" prepulses, was examined. METHODS Prepulses of 80, 85, and 90 dB(A) were presented on their own or followed by a pulse of 115 dB(A) (lead interval: ...
متن کاملPsychophysiological responses to auditory change.
A comprehensive characterization of autonomic and somatic responding within the auditory domain is currently lacking. We studied whether simple types of auditory change that occur frequently during music listening could elicit measurable changes in heart rate, skin conductance, respiration rate, and facial motor activity. Participants heard a rhythmically isochronous sequence consisting of a re...
متن کاملVisual-induced expectations modulate auditory cortical responses
Active sensing has important consequences on multisensory processing (Schroeder et al., 2010). Here, we asked whether in the absence of saccades, the position of the eyes and the timing of transient color changes of visual stimuli could selectively affect the excitability of auditory cortex by predicting the "where" and the "when" of a sound, respectively. Human participants were recorded with ...
