What are feature detectors?

Question

Quizplus · Accepted Answer

Feature detectors are neurons that fire in response to specific features (such as edges, lines, corners, and movement) of sensed stimuli in the environment. They are responsible for the initial processing of sensory information in the visual cortex of the brain. A is incorrect as it describes sensory receptors whereas feature detectors are neurons in the brain. C is incorrect as it describes visible light rather than neurons in the brain. D is incorrect as it refers to the absolute threshold, which is the minimum level of stimulation required for a stimulus to be detected 50% of the time.
