Thirty years of a very special visual area, Area V5.
In the late 1960s, I began to work on a large and ill-defined cortical zone surrounding the primary visual cortex (V1) and known indifferently as the ‘visual association cortex’. It seemed to me at the time that the work of Hubel and Wiesel had extracted as much juice out of V1 as was then possible, even though many were still working on it. The ‘association’ cortex, by contrast, had attracted ...
متن کاملArea V5—a microcosm of the visual brain
Area V5 of the visual brain, first identified anatomically in 1969 as a separate visual area, is critical for the perception of visual motion. As one of the most intensively studied parts of the visual brain, it has yielded many insights into how the visual brain operates. Among these are: the diversity of signals that determine the functional capacities of a visual area; the relationship betwe...
متن کاملMotion-from-hue activates area V5 of human visual cortex.
We designed experiments to ascertain whether area V5 of human visual cortex is activated by a motion stimulus in which luminance is made irrelevant, and motion is generated from hue differences alone. The stimuli consisted of moving green squares or bars against a red background, masked with luminance noise. Changes in regional cerebral blood flow (rCBF) were determined by the technique of posi...
متن کاملTranscranial magnetic stimulation of visual area V5 in migraine.
OBJECTIVE To examine visual cortical excitability in persons with migraine using transcranial magnetic stimulation (TMS) over an extrastriate area of the brain, area V5. BACKGROUND Previous studies found that persons with migraine have a lower phosphene threshold than healthy control subjects with TMS delivered over the primary visual cortical area V1. The result suggests that the occipital c...
متن کاملNeurons in dorsal visual area V5/MT signal relative disparity.
Judgments of visual depth rely crucially on the relative binocular disparity between two visual features. While areas of ventral visual cortex contain neurons that signal the relative disparity between spatially adjacent visual features, the same tests in dorsal visual areas yield little evidence for relative disparity selectivity. We investigated the sensitivity of neurons in dorsal visual are...
