Functional imaging studies in humans have identified an area in the fusiform gyrus which is selectively activated by stimulation when exposed to faces called the fusiform face area (FFA). [4] Another area known to be activated by face stimuli is the superior temporal sulcus (STS). This region is particularly active when having to process facial ...
Prosopagnosia, [2] also known as face blindness, [3] is a cognitive disorder of face perception in which the ability to recognize familiar faces, including one's own face (self-recognition), is impaired, while other aspects of visual processing (e.g., object discrimination) and intellectual functioning (e.g., decision-making) remain intact.
This is because processing inverted faces involves a piecemeal strategy. C.K.'s performance is compared to patients with prosopagnosia who are impaired in face processing but perform well identifying inverted faces. This was the first evidence for a double dissociation between face and object processing suggesting a face-specific processing system.

A common example is the perception of a face within an inanimate object—the headlights and grill of an automobile may appear to be "grinning". People around the world see the "Man in the Moon". [8] People sometimes see the face of a religious figure in a piece of toast or in the grain of a piece of wood.
Vision has been known to play an important role in balance and postural control in humans, along with proprioception and vestibular function. Monocular vision affects how the brain perceives its surroundings by decreasing the available visual field, impairing peripheral vision on one side of the body, and compromising depth perception, all ...
The neuropsychological side of visual information processing is known as visual perception, an abnormality of which is called visual impairment, and a complete absence of which is called blindness. The visual system also has several non-image forming visual functions, independent of visual perception, including the pupillary light reflex and ...
Bruce & Young Model of Face Recognition, 1986. One of the most widely accepted theories of face perception argues that understanding faces involves several stages: [7] from basic perceptual manipulations on the sensory information to derive details about the person (such as age, gender or attractiveness), to being able to recall meaningful details such as their name and any relevant past ...
