Original Source: Visual adaptation and face perception.
The appearance of faces can be strongly affected by the characteristics of faces viewed previously. These perceptual after-effects reflect processes of sensory adaptation that are found throughout the visual system, but which have been considered only relatively recently in the context of higher level perceptual judgements. In this review, we explore the consequences of adaptation for human face perception, and the implications of adaptation for understanding the neural-coding schemes underlying the visual...

Visual acuity (VA) is acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain. Visu...
Ophthalmology is the branch of medicine that is devoted to the study and treatment of eye diseases. As well as mild visual defects correctable by lenses, ophthalmology is concerned with glaucoma,...
Tinnitus causes people to hear constant sounds in one ear, both ears or in their head. Tinnitus is the medical name for the perception of noise in one ear, both ears or in the head. The noise comes...

Adaptation maintains population homeostasis in primary visual cortex
In primary visual cortex (V1), adaptation controls the responsiveness of individual neurons and shifts their visual selectivity. Here the authors examine adaptation at the population level. They concl...
The visual system as economist: Neural resource allocation in visual adaptation
(Medical Xpress)—It has long been held that in a new environment, visual adaptation should improve visual performance. However, evidence has contradicted this expectation: Adaptation sometimes not o...
(Medical Xpress)—The apparent ease and immediacy of human perception is deceptive, requiring highly complex neural operations to determine the category of objects in a visual scene. Nevertheless, th...
Conscious perception has little to do with primary visual cortex, research suggests
Imaging data suggest that conscious perception has little to do with the primary visual cortex —- the region where visual information enters the brain. From a purely intuitive point of view, it is e...
Visual Errors Twist and Tickle the Mind (preview)
Visual perception begins with our retinas locating the edges of objects in the world. Downstream neural mechanisms analyze those borders and use that information to fill in the insides of objects, con...
This fascinating review provides a neurobiological perspective on visual agnosias -- disorders that impair the perception and recognition of color, words, objects, and faces. Practical Neurology
Sensory Information Suppressed By Those With High IQ
People with high IQ scores aren't just more intelligent. They also process sensory information differently, according to a study reported in the Cell Press journal Current Biology. The findings show t...
Precisely targeted electrical brain stimulation alters perception of faces, study finds
In a painless clinical procedure performed on a patient with electrodes temporarily implanted in his brain, Stanford University doctors pinpointed two nerve clusters that are critical for face percept...

Overlapping facial expression representations are identity-dependent.
Influential cognitive models of face perception posit that facial expression and identity are processed by independent visual systems. Recent research indicates these systems interact and that represe...
The many faces of research on face perception.
Face perception is fundamental to human social interaction. Many different types of important information are visible in faces and the processes and mechanisms involved in extracting this information...
Can you McGurk yourself? Self-face and self-voice in audiovisual speech.
We are constantly exposed to our own face and voice, and we identify our own faces and voices as familiar. However, the influence of self-identity upon self-speech perception is still uncertain. Speec...
Sustained effects of adaptation on the perception of familiar faces.
Figural aftereffects are commonly believed to be transient and to fade away in the course of milliseconds. We tested face aftereffects using familiar faces and found sustained effects lasting up to 1...
