Response force is sensitive to the temporal uncertainty of response stimuli

An fMRI study of human visual cortex in response to spatiotemporal properties of visual stimuli

  ABSTRACT  Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF).  Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd.  Results: Average percentage BOLD signa...

Inhibition during response preparation is sensitive to response complexity.

Motor system excitability is transiently suppressed during the preparation of movement. This preparatory inhibition is hypothesized to facilitate response selection and initiation. Given that demands on selection and initiation processes increase with movement complexity, we hypothesized that complexity would influence preparatory inhibition. To test this hypothesis, we probed corticospinal exc...

The TPP Is Dead, Long Live the TPP? A Response to Recent Commentaries

Response of cutaneous A- and C-fiber nociceptors in the monkey to controlled-force stimuli.

The goal of this study was to determine the capacity of primary afferent nociceptive fibers (nociceptors) to encode information about noxious mechanical stimuli in primates. Teased-fiber techniques were used to record from 14 A-fiber nociceptors and 18 C-fiber nociceptors that innervated the hairy skin. Stimulus-response functions were examined with an ascending series of force-controlled stimu...
