Standardization of Latency and Amplitude Values of Short, Middle and Long Latency Auditory Evoked Potentials in Adults

open access: yesInternational Archives of Otorhinolaryngology, 2023
Introduction Auditory processing refers to the efficiency and effectiveness with which the central auditory nervous system uses auditory information. Middle- and long-latency auditory evoked potentials are objective electrophysiological tests that can ...

A study of changes in cognitive evoked potentials in persons with visual impairment [PDF]

open access: yesE3S Web of Conferences, 2021
In this work we have used psychophysiological assessments of the human brain electrical activity according to the classical neurological method for calculating the evoked potential.

Update on the multimodal pathophysiological dataset of gradual cerebral ischemia in a cohort of juvenile pigs: auditory, sensory and high-frequency sensory evoked potentials [PDF]

open access: yes, 2021
We expand from a spontaneous to an evoked potentials (EP) data set of brain electrical activities as electrocorticogram (ECoG) and electrothalamogram (EThG) in juvenile pig under various sedation, ischemia and recovery states. This EP data set includes three stimulation paradigms: auditory (AEP, 40 and 2000 Hz), sensory (SEP, left and right maxillary ...

Heart–brain interactions shape somatosensory perception and evoked potentials

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance Our brain continuously receives signals from the body and the environment. Although we are mostly unaware of internal bodily processes, such as our heartbeats, they can affect our perception.

Characterizing and minimizing the contribution of sensory inputs to TMS-evoked potentials

open access: yesBrain Stimulation, 2018
Background Transcranial magnetic stimulation (TMS) evokes voltage deflections in electroencephalographic (EEG) recordings, known as TMS-evoked potentials (TEPs), which are increasingly used to study brain dynamics.

Auditory Evoked Potential Mismatch Negativity in Normal-Hearing Adults

open access: yesInternational Archives of Otorhinolaryngology, 2017
Introduction Mismatch Negativity (MMN) corresponds to a response of the central auditory nervous system. Objective The objective of this study is to analyze MMN latencies and amplitudes in normal-hearing adults and compare the results ...

Evoked potentials as a biomarker of remyelination

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2019
Significance Remyelination is a critical therapeutic target in MS that will restore function and protect demyelinated axons. Clinical trials of putative remyelination-promoting drugs depend on valid, robust, and noninvasive outcome measures. To date, MRI

Multimodal evoked potentials and the ovarian cycle in young ovulating women [PDF]

open access: yesArquivos de Neuro-Psiquiatria, 2000
There is controversy over how hormonal conditions influence cerebral physiology. We studied pattern-shift visual evoked potentials (PS-VEP), brain stem auditory evoked potentials (BAEP) and short-latency somatosensory evoked potentials (SSEV) in 20 ...

Dermatomal somatosensory evoked potentials and cortical somatosensory evoked potentials assessment in congenital scoliosis

open access: yesBMC Neurology, 2022
Background The aim of this study was to assess the value of dermatomal somatosensory evoked potentials (DSEPs) and cortical somatosensory evoked potentials (SSEPs) in monitoring spinal cord function for patients with congenital scoliosis (CS).

Evoked potential variability [PDF]

open access: yesJournal of Neuroscience Methods, 2009
An unsupervised correlation-based clustering method was developed to assess the trial-to-trial variability of auditory evoked potentials (AEPs). The method first decomposes single trials into three frequency bands, each containing activity primarily associated with one of the three major AEP components, i.e., P50, N100 and P200.
