The binaural masking level difference: cortical correlates persist despite severe brain stem atrophy in progressive supranuclear palsy.

abstract：:The respective roles of ventral and dorsal cortical processing streams are still under discussion in both vision and audition. We characterized neural responses in the caudal auditory belt cortex, an early dorsal stream region of the macaque. We found fast neural responses with elevated temporal precision as well as n...
