Early contingentnegative variation of the EEG and attentional flexibility are reduced in hypotension [PDF]

open access: yes, 2002
This study explored the question as to whether hypotension is related to decreased attentional performance and reduced cortical activation. A total of 50 females aged 19 44 years participated in the study. Attentional performance was assessed using three

Modulation of early and late event-related potentials by emotion

open access: yesFrontiers in Integrative Neuroscience, 2012
Although emotionally salient stimuli influence higher order information processing, the relative vulnerability of specific stages of cognitive processing to modulation by emotional input remains elusive.

Learning to predict: Neuronal signatures of auditory expectancy in human event-related potentials

open access: yesNeuroImage, 2021
Learning to anticipate future states of the world based on statistical regularities in the environment is a key component of perception and is vital for the survival of many organisms.

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

open access: yes, 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

Adaptive Cognitive Control in Prematurely Born Children: An HD-EEG Investigation

open access: yesBrain Sciences, 2022
Preterm birth is a neurodevelopmental risk condition often associated with cognitive control (CC) impairment. Recent evidence showed that CC can be implicitly adapted through associative learning.

Perceptual inequality between two neighboring time intervals defined by sound markers: correspondence between neurophysiological and psychological data

open access: yesFrontiers in Psychology, 2014
Brain activity related to time estimation processes in humans was analyzed using a perceptual phenomenon called auditory temporal assimilation. In a typical stimulus condition, two neighboring time intervals (T1 and T2 in this order) are perceived as ...

Mismatch Negativity and Stimulus-Preceding Negativity in Paradigms of Increasing Auditory Complexity: A Possible Role in Predictive Coding

open access: yesEntropy, 2021
The auditory mismatch negativity (MMN) has been considered a preattentive index of auditory processing and/or a signature of prediction error computation.

Increased performance uncertainty in children with ADHD? - Elevated post-imperative negative variation (PINV) over the ventrolateral prefrontal cortex

open access: yes, 2011
Background: We aimed to investigate the influences of attention deficit/hyperactivity disorder (ADHD) on response evaluation, as reflected by the postimperative negative variation (PINV), a slow event-related potential.

Bereitschaftspotential preceding eyelid blinks in Parkinson’s disease

open access: yesArquivos de Neuro-Psiquiatria
The Bereitschaftspotential (BP) is a negative wave observed in EEG retrograde averaging, preceding a motor act. The objective was to study the BP preceding voluntary eyelid blinks in Parkinson’s disease (PD) patients during off and on phases of levodopa.

Increased anticipatory contingent negative variation in posttraumatic stress disorder

open access: yes, 2016
Contains fulltext : 167881.pdf (Publisher’s version ) (Open Access)Altered anticipation processes are implicated across various clinical samples, but few studies focused on the posttraumatic stress disorder (PTSD).
