SSVEP phase synchronies and propagation during repetitive visual stimulation at high frequencies

Scientific Reports, 2021
Steady-state visual evoked potentials (SSVEPs), the brain response to visual flicker stimulation, have proven beneficial in both research and clinical applications.

Brain–computer control interface design for virtual household appliances based on steady-state visually evoked potential recognition

Visual Informatics, 2020
Brain–computer interface is a new form of interaction between humans and machines. This interaction helps the human brain control or operate external devices directly using electroencephalograph (EEG) signals.

An electrocorticographic BCI using code-based VEP for control in video applications: A single-subject study

Frontiers in Systems Neuroscience, 2014
A brain-computer-interface (BCI) allows the user to control a device or software with brain activity. Many BCIs rely on visual stimuli with constant stimulation cycles that elicit steady-state visual evoked potentials (SSVEP) in the electroencephalogram (

Face-evoked steady-state visual potentials: effects of presentation rate and face inversion

Frontiers in Human Neuroscience, 2012
Face processing can be explored using electrophysiological methods. Research with event-related potentials (ERPs) has demonstrated the so-called face inversion effect, in which the N170 component is enhanced in amplitude and latency to inverted, compared

Computational exploration of dynamic mechanisms of steady state visual evoked potentials at the whole brain level

NeuroImage, 2021
Periodic visual stimulation can induce stable steady-state visual evoked potentials (SSVEPs) distributed in multiple brain regions and has potential applications in both neural engineering and cognitive neuroscience.

Flash visual evoked potentials in patients with periventricular leucomalacia in children less than 1 year of age

Indian Journal of Ophthalmology, 2013
Background and Aim: Children with periventricular leucomalacia (PVL) are known to have visual impairment of various forms starting from reduced vision, field defects, congnitive problems, and problems with hand eye coordination.

Cingulate cortex function and multi-modal connectivity mapped using intracranial stimulation

NeuroImage, 2020
The cingulate cortex is part of the limbic system. Its function and connectivity are organized in a rostro-caudal and ventral-dorsal manner which was addressed by various other studies using rather coarse cortical parcellations.

Decreased peak alpha frequency and impaired visual evoked potentials in first episode psychosis

NeuroImage: Clinical, 2019
Abnormal spontaneous and evoked oscillations have been reported in several studies of patients with psychotic disorders. Resting alpha power and peak alpha frequency may be decreased in patients with psychosis. We used high-density EEG (hd-EEG) to record

Impaired Potentiation of Theta Oscillations During a Visual Cortical Plasticity Paradigm in Individuals With Schizophrenia

Frontiers in Psychiatry, 2020
Long-term potentiation (LTP) is a form of experience-dependent synaptic plasticity mediated by glutamatergic transmission at N-methyl-D-aspartate receptors (NMDARs).

Transcranial ultrasound neuromodulation of the thalamic visual pathway in a large animal model and the dose-response relationship with MR-ARFI

Scientific Reports, 2022
Neuromodulation of deep brain structures via transcranial ultrasound stimulation (TUS) is a promising, but still elusive approach to non-invasive treatment of brain disorders.
