Cortical Off Response Tuning for Stimulus Duration

To answer the question whether OFF response amplitude (firing rate) of visual cortical cells varies as a function of stimulus duration, a series of such cells from areas 17 and 18 of the cat were investigated with a stationary light bar, presented for different durations (10-3200 msec) over the receptive field. Out of a sample of 174 cells tested, 58 cells were found for which the OFF responses...

A Simon effect for stimulus-response duration.

A non-spatial variant of the Simon effect for the stimulus-response (S-R) feature of duration is reported. In Experiment 1 subjects were required to press a single response key either briefly or longer in response to the colour of a visual stimulus that varied in its presentation duration. Short keypresses were initiated faster with short than with long stimulus duration whereas the inverse was...

The effect of stimulus duty cycle and "off" duration on BOLD response linearity.

An ongoing question in functional MRI is precisely how measured signal changes relate to neuronal activity. While this question has been probed using animal models and electrophysiologic measures of neuronal activity, it has also been probed by examining, in humans, the spatial location, magnitude, and temporal dynamics of signal changes to well understood stimuli. With regard to dynamics, seve...

Choice and stimulus-response compatibility affect duration of response selection.

In general, for movements to visual targets, response times increase with the number of possible response choices. However, this rule only seems to hold when an incompatibility exists between the stimulus and response, and is absent when stimulus and response are highly compatible (e.g., when reaching toward the location of the stimulus). Stimulus-response (S-R) compatibility can be manipulated...

Optimal Neuronal Tuning for Finite Stimulus Spaces

The efficiency of neuronal encoding in sensory and motor systems has been proposed as a first principle governing response properties within the central nervous system. We present a continuation of a theoretical study presented by Zhang and Sejnowski, where the influence of neuronal tuning properties on encoding accuracy is analyzed using information theory. When a finite stimulus space is cons...
