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 ...

Bifocals in the brain: Visual information from near and far space processed with differing degrees of acuity

Neuroscientists from Tübingen have discovered how our brain processes visual stimuli above and below the horizon differently. The researchers led by Dr. Ziad Hafed of the Werner Reichardt Centre for ...

Researchers identify a new eye movement in human studies.

The purpose of blinks is to keep the eyes hydrated and to protect them. Blinks are rarely noticed by the subject as blink-induced alterations of visual input are blanked out without jeopardizing the p...

Allen Institute Launches Brain Observatory

The Allen Institute for Brain Science today launched a highly standardized survey of cellular-level activity in the mouse visual system designed to help researchers investigate how circuits in the m...

Why do people with Alzheimer's stop recognizing their loved ones?

(University of Montreal) A recent study has demonstrated that, beyond causing memory problems, Alzheimer's disease also impairs visual face perception. This finding may help families better understan...

Why do people with Alzheimer’s stop recognizing their loved ones?

Alzheimer’s not only steals people’s memories but also their ability to recognize faces, which widens the gulf between people with this disease and their loved ones. A recent study h...

Cuing environmental responses in fungi

Fungi can sense environmental signals and react accordingly, changing their development, direction of growth, and metabolism. Sensory perception lies at the heart of adaptation to changing conditions,...

Linking pattern completion in the hippocampus to predictive coding in visual cortex

Expectations about what will appear next guide perception. Using high-resolution fMRI and multivariate pattern analysis, the authors find that such predictive coding in early visual cortex could arise...

Faces in Context: Does Face Perception Depend on the Orientation of the Visual Scene?

The mechanisms held responsible for familiar face recognition are thought to be orientation dependent; inverted faces are more difficult to recognize than their upright counterparts. Although this eff...

Neural mechanisms of face perception, their emergence over development, and their breakdown.

Face perception is probably the most developed visual perceptual skill in humans, most likely as a result of its unique evolutionary and social significance. Much recent research has converged to iden...

The cognitive and neural basis of developmental prosopagnosia.

Developmental prosopagnosia (DP) is a severe impairment of visual face recognition in the absence of any apparent brain damage. The factors responsible for DP have not yet been fully identified. This ...

Facial Expression Aftereffect Revealed by Adaption to Emotion-Invisible Dynamic Bubbled Faces.

Visual adaptation is a powerful tool to probe the short-term plasticity of the visual system. Adapting to local features such as the oriented lines can distort our judgment of subsequently presented l...

Action adaptation during natural unfolding social scenes influences action recognition and inferences made about actor beliefs.

When observing another individual's actions, we can both recognize their actions and infer their beliefs concerning the physical and social environment. The extent to which visual adaptation influence...
