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...

Memory reactivation improves visual perception

Human perception can improve through repeated practice, enabling perceptual learning. The authors report findings challenging the fundamental ‘practice makes perfect’ basis of procedural learning ...

Coupling of movement and vision

In a study published in Cell, Georg Keller and his group shed light on neural circuits in the cortex that underlie the integration of movement and visual feedback. They identified a mechanism in the v...

Computations of visual motion in the brain

Botond Roska and his group at the FMI have elucidated how the retina and the visual cortex work together in visual motion perception. They found that cortical cells, which respond preferentially to ba...

You don't see what I see? Visual perception may depend on birthplace and environment

Perhaps we only see what we've learned to see.

Blind people use ‘brain map’ to differentiate between visual categories

Is what you're looking at an object, a face, or a tree? When processing visual input, our brain uses different areas to recognize faces, body parts, scenes, and objects.

Body dysmorphic disorder visual retraining program

A world-first study is aiming to alleviate symptoms of those with body dysmorphic disorder (BDD) through a unique visual retraining program. BDD results in an exaggerated perception of aspects of pers...

Visual perception may depend on birthplace and environment

Researchers shows that an ability to perceive differences between similar images depends on the cultural background of the viewer.

Crystalens may affect patients' perception of colors

The Crystalens accommodating implant from Bausch + Lomb is designed to provide patients with improved refractive and visual outcomes at distance and intermediate. Most patients experience a change in ...

Adaptation reveals that facial expression averaging occurs during rapid serial presentation.

How do we interpret the rapidly changing visual stimuli we encounter? How does our past visual experience shape our perception? Recent work has suggested that our visual system is able to interpret mu...

Dissociation between the neural correlates of conscious face perception and visual attention.

Given the higher chance to recognize attended compared to unattended stimuli, the specific neural correlates of these two processes, attention and awareness, tend to be intermingled in experimental de...

The Involvement of Centralized and Distributed Processes in Sub-second Time Interval Adaptation: An ERP Investigation of Apparent Motion.

Accumulating evidence suggests that the timing of brief stationary sounds affects visual motion perception. Recent studies have shown that auditory time interval can alter apparent motion perception n...

Proficient use of low spatial frequencies facilitates face memory but shows protracted maturation throughout adolescence.

Face perception is characterized by configural processing, which depends on visual information in the low spatial frequency (LSF) ranges. However, it is unclear whether LSF content is equally importan...

The effect of face patch microstimulation on perception of faces and objects.

What is the range of stimuli encoded by face-selective regions of the brain? We asked how electrical microstimulation of face patches in macaque inferotemporal cortex affects perception of faces and o...
