AP PSYCHOLOGY

Detailed explanation-1: -Cells in the visual cortex, called feature cells or feature detectors, respond selectively to various components of a visual image, such as orientation of lines, colour, and movement.

Detailed explanation-2: -The three major groups of so-called feature detectors in visual cortex include simple cells, complex cells, and hypercomplex cells. Simple cells are the most specific, responding to lines of particular width, orientation, angle, and position within visual field.

Detailed explanation-3: -Visual stimuli from our surroundings are processed by an intricate system of interconnecting neurons, which begins with the optic nerve in the eye up to the visual processing center in our forebrain called the visual cortex.

Detailed explanation-4: -Feature detectors are individual neurons-or groups of neurons-in the brain which code for perceptually significant stimuli. Early in the sensory pathway feature detectors tend to have simple properties; later they become more and more complex as the features to which they respond become more and more specific.
