Cortical activity patterns predict speech discrimination ability

摘要: Neural activity in the cerebral cortex can explain many aspects of sensory perception. Extensive psychophysical and neurophysiological studies visual motion vibrotactile processing show that firing rate cortical neurons averaged across 50–500 ms is well correlated with discrimination ability. In this study, we tested hypothesis primary auditory (A1) use temporal precision on order 1–10 to represent speech sounds shifted into rat hearing range. was highly behavioral performance 11 consonant-discrimination tasks when spike timing preserved not eliminated. This result suggests contributes representation consonant sounds.
