This is the question:::: discuss what visual information is processed by the retina and by simple and complex cells in V1, and what the differences are between these levels of information processing.

Answer 1

Answer:- Vision starts with light passing through the cornea and lens, merging to create a clear view of the visual world on a photoreceptor surface called the retina. The picture on the retina is reversed as in a camera: Artifacts to the lower part above the middle project and vice versa.

Complex cells can be located in the central visual cortex (V1), secondary visual cortex (V2), and region 19 (V3) of Brodmann. Like a simple cell, a complex cell will primarily respond to directed edges and gratings, though it has some degree of spatial invariance.

The M-stream of information processed by interblob cells of motion sensitive V1 is used to detect movement of objects and direction / velocity of movement, as well as to guide eye movements. The "motion sensing" cells of V1 are these motion-sensitive interblob cells.

Low-level visual processing is concerned with assessing the different types of contrast between images projected onto the retina while high-level visual processing refers to cognitive processes that incorporate information from a variety of sources into the visual information expressed in one's consciousness.
