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 ...

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.

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

The steady-state visual evoked potential in vision research : a review

, 2015
Periodic visual stimulation and analysis of the resulting steady-state visual evoked potentials were first introduced over 80 years ago as a means to study visual sensation and perception. From the first single-channel recording of responses to modulated

Spatiotemporal Beamforming: A Transparent and Unified Decoding Approach to Synchronous Visual Brain-Computer Interfacing

Frontiers in Neuroscience, 2017
Brain-Computer Interfaces (BCIs) decode brain activity with the aim to establish a direct communication channel with an external device. Albeit they have been hailed to (re-)establish communication in persons suffering from severe motor- and/or ...

Low-Frequency Local Field Potentials and Spikes in Primary Visual Cortex Convey Independent Visual Information [PDF]

, 2008
Local field potentials (LFPs) reflect subthreshold integrative processes that complement spike train measures. However, little is yet known about the differences between how LFPs and spikes encode rich naturalistic sensory stimuli.
