Unformatted text preview: structed patients to move eyes to where the light was. And they would
verbally report that they can't see, but would still "guess" correctly more often than by chance. Thus, their hypothesis is that there is subcortical
pathway that is bypassing V1 that could be enough to produce a response but not enough to create conscious awareness of it. The Nature of Receptive Fields!
Receptive Fields: the area of the external
visual space within which a stimulus must
be presented in order to activate a visual
neuron. In addition to the spatial position,
the neurons may be selective to other
stimulus features, such as orientation,
color, or shape. ! David Hubel and Torsten Wiesel won the 1961
Nobel Prize in Physiology or Medicine for their
experiments on the visual system of cats.! Each point along the visual cortex, or the pathway for that matter, are responsive to a stimuli that occurs in one area, or at one point, the visual world.
First discovered doing cell recording in cats and monkeys. Discovered that when they inserted this electrodes in V1 the cells would beco...
