Clinical And Electrophysiological Correlation In Patient With Optic Neuritis
Revista Cubana de Investigaciones Biomédicas, 2019 A descriptive and traverse study was performed in patients with diagnosis of optic neuritis, that attended to the neuro ophthalmology service of the ophthalmological center, at the Santiago General Hospital "Dr.

Dynamic and integrated mechanical movements of a rat brain associated with evoked potentials [PDF]
arXiv, 2014 By using a piezoelectric sensor, it was demonstrated that the visual evoked potential of a rat brain was accompanied by mechanical movements of the brain when it was excited. A phase of upward movement was found to be followed by a phase of downward movement.

Compact Convolutional Neural Networks for Classification of Asynchronous Steady-state Visual Evoked Potentials [PDF]
, 2018 Steady-State Visual Evoked Potentials (SSVEPs) are neural oscillations from the parietal and occipital regions of the brain that are evoked from flickering visual stimuli. SSVEPs are robust signals measurable in the electroencephalogram (EEG) and are commonly used in brain-computer interfaces (BCIs).

Cortical Excitability Before and After Long‐Term Perampanel Treatment for Epilepsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Antiseizure medications (ASMs), which may influence cortical excitability, are the mainstay of epilepsy treatment. Transcranial magnetic stimulation (TMS) helps evaluate cortical excitability. We assessed changes in TMS responses using serial TMS measurements in people treated with an adjunctive noncompetitive AMPA‐receptor ...

Visual motion-evoked potentials in man [PDF]
, 1972 Visual motion-evoked potentials were recorded from the human scalp. The stimulus chosen for most detailed study was sudden reversal of the motion of a patterned field, on the hypothesis that this was likely to activate only mechanisms selectively ...

Visual Evoked Potentials in Neuromyelitis Optica Spectrum Disorders
Journal of Central Nervous System Disease, 2021 Background Neuromyelitis optica spectrum disorders (NMOSDs) are rare antibody-mediated disorders of the central nervous system, with a predilection for the spinal cord and optic nerves.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To investigate the reliability of very high‐frequency oscillations (VHFOs, 500–2000 Hz) as biomarkers in identifying the epileptogenic zone (EZ) in mesial temporal lobe epilepsy (MTLE) patients. Methods We reviewed 19 MTLE patients who underwent stereo‐electroencephalography‐guided radiofrequency thermocoagulation.

A comparative study on long-term evoked auditory and visual potential responses between Schizophrenic patients and normal subjects [PDF]
, 2011 Background The electrical signals measuring method is recommended to examine the relationship between neuronal activities and measure with the event related potentials (ERPs) during an auditory and a visual oddball paradigm between schizophrenic patients

Influence of visual angle on pattern reversal visual evoked potentials
Oman Journal of Ophthalmology, 2014 Purpose: The aim of this study was to find whether the visual evoked potential (VEP) latencies and amplitude are altered with different visual angles in healthy adult volunteers or not and to determine the visual angle which is the optimum and most ...
