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

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...

Tinnitus

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 ...

Cleft Palate and Cleft Lip

Cleft means 'split' or 'separation', and in Cleft Palate and Lip, the palate and lip are split respectively. This occurs as a congenital abnormality because during development in the...

Tactile frequency discrimination is enhanced by circumventing neocortical adaptation

During adaptation, neocortical responses change as a result of repeated sensory stimulation, but it's unclear how this affects perception. Here the authors use optogenetics to mimic sensory evoked cor...

Amblyopia In Early Childhood May Alter Speech Perception

Children with unresolved amblyopia during early childhood may have difficulty with visual-auditory speech integration and subsequent alterations in speech perception. Medscape Medical News

Declining intelligence in old age linked to visual processing

Researchers have uncovered one of the basic processes that may help to explain why some people's thinking skills decline in old age. Age-related declines in intelligence are strongly related to declin...

Key brain region responds to subjective perception in study of individual neuron activity

When evaluating another person’s emotions – happy, sad, angry, afraid – humans take cues from facial expressions. Neurons in a part of the brain called the amygdala “fire” in response to the...

In study of individual neuron activity, key brain region responds to subjective perception

LOS ANGELES (June 30, 2014) – When evaluating another person's emotions – happy, sad, angry, afraid – humans take cues from facial expressions. Neurons in a part of the brain called the amygdala...

Interactions between concentric form-from-structure and face perception revealed by visual masking but not adaptation.

Findings from diverse subfields of vision research suggest a potential link between high-level aspects of face perception and concentric form-from-structure perception. To explore this relationship, t...

Imagining sex and adapting to it: Different aftereffects after perceiving versus imagining faces.

A prolonged exposure (i.e., perceptual adaptation) to a male or a female face can produce changes (i.e., aftereffects) in the subsequent gender attribution of a neutral or average face, so that it app...

Noise and adaptation in multistable perception: Noise drives when to switch, adaptation determines percept choice.

We study the dynamics of perceptual switching in ambiguous visual scenes that admit more than two interpretations/percepts to gain insight into the dynamics of perceptual multistability and its underl...

The sound of your lips: electrophysiological cross-modal interactions during hand-to-face and face-to-face speech perception.

Recent magneto-encephalographic and electro-encephalographic studies provide evidence for cross-modal integration during audio-visual and audio-haptic speech perception, with speech gestures viewed or...

Face perception is tuned to horizontal orientation in the N170 time window.

The specificity of face perception is thought to reside both in its dramatic vulnerability to picture-plane inversion and its strong reliance on horizontally oriented image content. Here we asked when...
