Activity of High-Frequency Vibratory Sensitive Neurons in Monkey PrimarySomatosensory Cortex during the Initiation of Vibratory and Visually Cued Hand Movements

摘要

The activity of high-frequency vibratory sensitive (nFVS) neurons was recorded inmonkey primary somatosensory cortex (SI) while animals performed wrist flexions and extensions in response to 27, 57 or 127 Hz palmar vibration or in response to visual stimuli serving as go-cues. HFVS neurons were distinguished by their best responsiveness to the highest frequency vibration (127 Hz) being better than to the lower frequencies. These neurons probably received input from Pacinian afferents. HFVS neurons formed a unique population that constituted.
