Abstract
Modulation of auditory responses by modality-specific attention in rat primary auditory cortex
Highlights
Does attending to a sound modulate the neural representation of that sound in auditory cortex? What’s the underlying mechanism?In order to answer these questions, we established a simple rodent model of modality-specific attention
Spontaneous activity: Center poke ~ tone onset On response:10~50ms after tone on enhanced: A > O 10 5 0 -5 -10 suppressed: A < O spontaneous Tone response
Modality-specific attention can strongly modulate neural responses evoked by exactly the same auditory stimulus in rat primary auditory cortex
Summary
Does attending to a sound modulate the neural representation of that sound in auditory cortex? What’s the underlying mechanism?In order to answer these questions, we established a simple rodent model of modality-specific attention.
