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 ...

Zone, visual acuity affect outcomes after traumatic injury

BOSTON — Patients with low visual acuity at presentation for a traumatic eye injury tended to have worse vision at final follow-up and a higher risk for enucleation, according to a poster presented ...

Appetizing imagery puts visual perception on fast forward

People rated images containing positive content as fading more smoothly compared with neutral and negative images, even when they faded at the same rate, according to new findings.

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...

Blur Adaptation to Central Retinal Disease.

The long-term, low-resolution vision experienced by individuals affected by retinal disease that causes central vision loss (CVL) may change their perception of blur through adaptation. This study use...
