Auditory edge detection in human auditory cortex
Acknowledgements: We are grateful to Jeff Walker for excellent technical support and to Alain de Cheveigné for comments and discussion. Auditory objects are detected if they differ acoustically from the ongoing background. In simple cases, the appearance or disappearance of the object
متن کاملGain Control in the Auditory Cortex Evoked by Changing Temporal Correlation of Sounds.
Natural sounds exhibit statistical variation in their spectrotemporal structure. This variation is central to identification of unique environmental sounds and to vocal communication. Using limited resources, the auditory system must create a faithful representation of sounds across the full range of variation in temporal statistics. Imaging studies in humans demonstrated that the auditory cort...
متن کاملEffect of neuregulin-1 on the auditory cortex in adult C57BL/6J mice
Objective(s): We sought to explore whether neuregulin-1(NRG1) would have a protective effect on the auditory cortices of adult C57BL/6J mice.Materials and Methods: We used RTPCR and Western blot (WB) to detect the expression of NRG1 and ERBB4 (the receptor of NRG1) in the auditory cortices of C57BL/6J mice of different ages (6–8 weeks an...
متن کاملRole of Amygdala-Infralimbic Cortex Circuitry in Glucocorticoid-induced Facilitation of Auditory Fear Memory Extinction
Introduction: The basolateral amygdala (BLA) and infralimbic area (IL) of the medial prefrontal cortex (mPFC) are two interconnected brain structures that mediate both fear memory expression and extinction. Besides the well-known role of the BLA in the acquisition and expression of fear memory, projections from IL to BLA inhibit fear expression and have a critical role in fear extinction. Howev...
متن کاملContrast tuning in auditory cortex.
The acoustic features useful for converting auditory information into perceived objects are poorly understood. Although auditory cortex neurons have been described as being narrowly tuned and preferentially responsive to narrowband signals, naturally occurring sounds are generally wideband with unique spectral energy profiles. Through the use of parametric wideband acoustic stimuli, we found th...
