Monkey primary somatosensory cortical activity during the early reaction time period differs with cues that guide movements
Vibration-related neurons in monkey primary somatosensory cortex (SI) discharge rhythmically when vibratory stimuli are presented. It remains unclear how functional information carried by vibratory inputs is c...

Neuronal activity in monkey primary somatosensory cortex is related to expectation of somatosensory and visual go-cues
The present study was to investigate whether neuronal activity in primary somatosensory cortical areas (SI) differs when monkeys expect go-cues of different sensory modalities. Two monkeys made wrist extension...

Neuronal activity in primary motor cortex differs when monkeys perform somatosensory and visually guided wrist movements
This study was designed to investigate how activity patterns of primary motor cortical (MI) neurons change when monkeys perform the same movements guided by somatosensory and/or visual cues. Two adult male rhe...

Simultaneous encoding of tactile information by three primate cortical areas
We used simultaneous multi-site neural ensemble recordings to investigate the representation of tactile information in three areas of the primate somatosensory cortex (areas 3b, SII and 2). Small neural ensemb...

High-frequency vibratory sensitive neurons in monkey primary somatosensory cortex: entrained and nonentrained responses to vibration during the performance of vibratory-cued hand movements
The activity of high-frequency vibratory sensitive (HFVS) neurons was recorded in monkey primary somatosensory cortex (SI) while animals performed wrist flexions and extensions in response to 57-Hz or 127-Hz p...

Rhythmically firing (20–50 Hz) neurons in monkey primary somatosensory cortex: Activity patterns during initiation of vibratory-cued hand movements
The activity patterns of rhythmically firing neurons in monkey primary somatosensory cortex (SI) were studied during trained wrist movements that were performed in response to palmar vibration. Of 1,222 neuron...

The Postcentral Somatosensory Cortex
Many of our present day concepts of the organization of somatosensory cortex stem from the landmark study of Woolsey, Marshall and Bard, first published in 1937 (7) and then more completely in 1942 (21). These...

Organization of the S I Cortex
Recent electrophysiological map** studies have led to a significant redefinition of the internal organization of “S I” of primates (11, 17). Classically, “SI” has been described as a single and at least larg...
