Unformatted text preview: he contralateral side of space, relative to the center of gaze.! Maintains retinotopic mapping. Maintained from the retina to the V1, and all these areas as well. If this
eyeball is looking straighthead at point B, the light will be shown on the B on the retina, and C to C etc.
etc. Maintain retinotopic mapping in the thalamus, and the thalamus sends projections to V1… And this is
useful b/c if you do an fMRI study you can map out visual cortex relatively accuratly and by moving light
can map out spatial for each individual subjects. The Nature of Receptive Fields!
Each distinct visual area has its own
As one area projects to the next area, the
retinotopic mapping is preserved.!
Many early visual areas tend to converge
onto a single visual area, making the
responsiveness of the visual areas more
complex as the processing travels further
As a result, the receptive ﬁelds also become
But, the visual system is not entirely
