Blue-yellow signals are enhanced by spatiotemporal luminance contrast in macaque V1.
We measured the color tuning of a population of S-cone-driven V1 neurons in awake, fixating monkeys. Analysis of randomly chosen color stimuli that were effective in evoking action potentials showed that these neurons received opposite sign input from the S cones and a combination of L and M cones. Surprisingly, these cells also responded to LM cone contrast irrespective of polarity, a nonlinea...
متن کاملPaucity of chromatic linear motion detectors in macaque V1.
The motion of a color-defined edge is often more difficult to perceive than the motion of a luminance-defined edge. Neurons subserving motion vision may therefore be particularly sensitive to luminance contrast. One class of neurons thought to play a critical role in motion perception is V1 neurons whose spatiotemporal receptive fields are oriented in space-time. We used the reverse correlation...
متن کاملCone inputs to simple and complex cells in V1 of awake macaque.
Rules by which V1 neurons combine signals originating in the cone photoreceptors are poorly understood. We measured cone inputs to V1 neurons in awake, fixating monkeys with white-noise analysis techniques that reveal properties of light responses not revealed by purely linear models used in previous studies. Simple cells were studied by spike-triggered averaging that is robust to static nonlin...
متن کاملShort-latency fixational saccades induced by luminance increments.
We investigated the effect of peripheral visual stimulation on small-amplitude saccades that occur naturally during fixation. Two macaque monkeys were rewarded for fixating while a colorful stimulus flickered randomly in the periphery. Reverse correlation revealed a lawful relationship between the stimulus sequence and saccade occurrences: on average, a transient increase in stimulus intensity ...
متن کامل1 V 1 mechanisms underlying chromatic contrast detection
25 To elucidate the cortical mechanisms of color vision, we recorded from individual V1 26 neurons in macaque monkeys performing a chromatic detection task. Roughly 30% of the 27 neurons we encountered were unresponsive at the monkeys’ psychophysical detection threshold. 28 The other 70% were responsive at threshold, but on average, were slightly less sensitive than the 29 monkey. For these neu...
