Impact of Orbitofrontal Lesions on Electrophysiological Signals in a Stop Signal Task [PDF]

Journal of Cognitive Neuroscience, 2014
Abstract Behavioral inhibition and performance monitoring are critical cognitive functions supported by distributed neural networks including the pFC. We examined neurophysiological correlates of motor response inhibition and action monitoring in patients with focal orbitofrontal (OFC) lesions (n = 12) after resection of a primary ...

EEG Correlates of Active Stopping and Preparation for Stopping in Chronic Tic Disorder

Brain Sciences, 2022
Motor inhibition is an important cognitive process involved in tic suppression. As the right frontal lobe contains important inhibitory network nodes, we characterized right superior, middle, and inferior frontal gyral (RSFG, RMFG, RIFG) event-related ...

The Difficulty in Numerical Computation Impacts Motor Decisions in a Stop-Signal Task. [PDF]

Eur J Neurosci
ABSTRACT The proper interpretation of environmental information is necessary for effective decision-making. The resulting cognitive burden may affect the entire process if interpretation is not instantaneous. In this study, we investigated how numerical distance (ND), a measure of cognitive demand in numerical comparisons, influences ...

Partial response electromyography as a marker of action stopping

eLife, 2022
Response inhibition is among the core constructs of cognitive control. It is notoriously difficult to quantify from overt behavior, since the outcome of successful inhibition is the lack of a behavioral response.

Improved response inhibition induced by attentional capture is associated with physical activity [PDF]

PeerJ, 2022
The ability to stop a response promptly when a stop signal is presented is named response inhibition. It is generally accepted that the process of response inhibition requires a subject to pay attention to the stop instruction and then cancel the action.

The role of stimulus salience and attentional capture across the neural hierarchy in a stop-signal task. [PDF]

PLoS ONE, 2011
Inhibitory motor control is a core function of cognitive control. Evidence from diverse experimental approaches has linked this function to a mostly right-lateralized network of cortical and subcortical areas, wherein a signal from the frontal cortex to ...

Stopping eyes and hands: Evidence for non-independence of stop and go processes and for a separation of central and peripheral inhibition

Frontiers in Human Neuroscience, 2014
In the stop-signal paradigm, participants perform a primary reaction task, for example a visual or auditory discrimination task, and have to react to a go stimulus as quickly as possible with a specified motor response. In a certain percentage of trials,

Lifespan changes in global and selective stopping and performance adjustments

Frontiers in Psychology, 2011
This study examined stopping and performance adjustments in four age groups (M ages: 8, 12, 21, and 76 years). All participants performed on three tasks, a standard two-choice task and the same task in which stop-signal trials were inserted requiring ...

Relationship between Speed of Response Inhibition and Ability to Suppress a Step in Midlife and Older Adults

Brain Sciences, 2021
In young adults, performance on a test of response inhibition was recently found to be correlated with performance on a reactive balance test where automated stepping responses must occasionally be inhibited.

Error detection in the stop signal task

NeuroImage, 2010
Previous error detection research has focused on error processing functions in the anterior cingulate cortex or on putative reinforcement learning roles of midbrain dopamine pathways. We studied error detection in 14 healthy adult volunteers using a novel fMRI design in the stop signal task (SST), a task which invokes numerous errors in performance and
