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 ...

Brilinta (TM) - ticagrelor, AstraZeneca's new heart drug

Brilinta - ticagrelor, AstraZeneca's new heart drug is a blood-thinning medicine designed to prevent dangerous blood clots in patients with serious chest pain or previous heart attacks. It re...

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 ...

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,...

Climate change: Metrics needed to track adaptation

A lesser-known success of the Paris climate agreement in 2015 is the 'global adaptation goal', an ambitious plan for adapting to climate change that reaches beyond national boundaries. This is importa...

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...

A New Look at Vision

A critical new discovery redefines the primary organizing principle of the visual cortex, and explains much of the illusory perception when we see light and dark stimuli -- Read more on ScientificAme...

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...

Point Me in the Right Direction: Same and Cross Category Visual Aftereffects to Directional Cues.

Of the many hand gestures that we use in communication pointing is one of the most common and powerful in its role as a visual referent that directs joint attention. While numerous studies have examin...

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...
