Dynamic Neuronal Information Processing of Vowel Sounds in Auditory Cortex

摘要: By simulating a hierarchical neural network model of the auditory cortex, we investigated neuronal bases for encoding and perception vowel sounds. We demonstrate that information about vowels is encoded by specific dynamic cell assembles, an applied sound mediated collective activation assembly corresponding to input. tried explain roles time-varying formant frequencies, which are one notable characteristics natural (vocalized) sounds in humans. frequency stimulation neurons advantageous propagating excitation throughout stimulus as compared with constant stimulation. suggest change frequencies may be essential enhancement cognitive performance on perception.
