Steady-state visual evoked potentials can be explained by temporal superposition of transient event-related responses [PDF]

, 2011
<p><b>Background:</b> One common criterion for classifying electrophysiological brain responses is based on the distinction between transient (i.e. event-related potentials, ERPs) and steady-state responses (SSRs).

Normative values of visual evoked potential in adults

Indian Journal of Ophthalmology, 2021
Purpose: Visual evoked potentials (VEP) are used to determine the function of visual pathway from the optic nerve to visual cortex. Various factors may affect VEP response, viz., technical and environmental.

Steady-state visual evoked potentials differentiate between internally and externally directed attention

NeuroImage, 2022
While attention to external visual stimuli has been extensively studied, attention directed internally towards mental contents (e.g., thoughts, memories) or bodily signals (e.g., breathing, heartbeat) has only recently become a subject of increased ...

Audio-visual speech perception: a developmental ERP investigation [PDF]

, 2013
Being able to see a talking face confers a considerable advantage for speech perception in adulthood. However, behavioural data currently suggest that children fail to make full use of these available visual speech cues until age 8 or 9.

Pattern visual evoked potentials in dyslexic versus normal children

Journal of Ophthalmic & Vision Research, 2015
Purpose: Presence of neurophysiological abnormalities in dyslexia has been a conflicting issue. This study was performed to evaluate the role of sensory visual deficits in the pathogenesis of dyslexia.

Visual evoked potentials in neurobrucellosis

Neurosciences, 2008
OBJECTIVE: To investigate whether visual evoked potentials (VEPs) are valuable for distinguishing between brucellosis with or without neurological involvement. METHODS: A total of 23 patients who were admitted to the Department of Infectious Diseases and Microbiology, and Neurology, Ministry of Health Ankara Education and Research Hospital, Ankara ...

Time-resolved influences of functional DAT1 and COMT variants on visual perception and post-processing [PDF]

, 2012
BACKGROUND: Dopamine plays an important role in orienting and the regulation of selective attention to relevant stimulus characteristics. Thus, we examined the influences of functional variants related to dopamine inactivation in the dopamine transporter
