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...

Putting vision into context

The Thalamus not only relays visual signals from the eye to the visual cortex as previously thought, but also conveys additional, contextual information. Integrating these different signals is essenti...

Thalamus found to add contextual information to visual signals

The thalamus not only relays visual signals from the eye to the visual cortex as previously thought, but also conveys additional, contextual information. Integrating these different signals is essenti...

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 ...

UMass Amherst neuroscientist receives $599,000 grant to study brain function

(University of Massachusetts at Amherst) Cognitive neuroscientist Rosie Cowell at UMass Amherst recently received a five-year, $599,619 NSF CAREER award to develop and test a theory of how memory inte...

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...

An objective measure of face identity adaptation with fast periodic visual stimulation.

The human brain is remarkably adept at extracting identity information from faces, although understanding this process remains a challenge. Here, a novel neural measure of objective discrimination bet...

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 causal role of face-selective neurons in face perception.

Many neurons in the inferior temporal cortex (IT) of primates respond more strongly to images of faces than to images of non-face objects. Such so-called "face neurons" are thought to be involved in f...

Adults with autism spectrum disorder show evidence of figural aftereffects with male and female faces.

The norm-based coding model of face perception posits that face perception involves an implicit comparison of observed faces to a representation of an average face (prototype) that is shaped by experi...

Effects of TMS to occipital face area on the perception of face viewpoint cued only by shape changes in the external contour of the face.

Changes in the outer contour of a face act as a cue to face viewpoint, and these changes can be captured using radial frequency (RF) pattern stimuli (Wilson et al., 2000). The face viewpoint aftereffe...
