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 ...

Tactile frequency discrimination is enhanced by circumventing neocortical adaptation

During adaptation, neocortical responses change as a result of repeated sensory stimulation, but it's unclear how this affects perception. Here the authors use optogenetics to mimic sensory evoked cor...

Want to distract someone? An emotional face might work

The sudden appearance of a face within our visual field can affect the motor action accompanying a gesture even if the face is totally unrelated to what we are doing and even if we try to ignore it. W...

Amblyopia In Early Childhood May Alter Speech Perception

Children with unresolved amblyopia during early childhood may have difficulty with visual-auditory speech integration and subsequent alterations in speech perception. Medscape Medical News

The Over and Under of Shoe Tying

This ADL requires bilateral hand coordination, manual dexterity, fine motor planning, and visual perception.

Faces that distract from actions

The sudden appearance of a face within our visual field can affect the motor action accompanying a gesture even if the face is totally unrelated to what we are doing and even if we try to ignore it. A...

The dissociable effects of punishment and reward on motor learning

Human motor adaptation is often described as an automatic process insensitive to reward- or punishment-based feedback. Contrary to this hypothesis, Galea et al. show through a double dissociation that...

Morphed images of Hollywood celebrities reveal how neurons make up your mind

(University of Leicester) Study reveals individual neurons in the human brain are triggered by the subject's conscious perception, rather than by the visual stimulus

Elderly brains learn, but maybe too much

A new study led by Brown University reports that older learners retained the mental flexibility needed to learn a visual perception task but were not as good as younger people at filtering out irrelev...

The sound of your lips: electrophysiological cross-modal interactions during hand-to-face and face-to-face speech perception.

Recent magneto-encephalographic and electro-encephalographic studies provide evidence for cross-modal integration during audio-visual and audio-haptic speech perception, with speech gestures viewed or...

Beyond the FFA: The role of the ventral anterior temporal Lobes in face processing.

Extensive research has supported the existence of a specialized face-processing network that is distinct from the visual processing areas used for general object recognition. The majority of this work...

Probing the functions of contextual modulation by adapting images rather than observers.

Countless visual aftereffects have illustrated how visual sensitivity and perception can be biased by adaptation to the recent temporal context. This contextual modulation has been proposed to serve a...

High temporal frequency adaptation compresses time in the Flash-Lag illusion.

Previous research finds that 20Hz temporal frequency (TF) adaptation causes a compression of perceived visual event duration. We investigate if this temporal compression affects further time-dependent...

Face-selective neurons maintain consistent visual responses across months.

Face perception in both humans and monkeys is thought to depend on neurons clustered in discrete, specialized brain regions. Because primates are frequently called upon to recognize and remember new i...
