Stop Signal Task

The Stop Signal Task is a laboratory task assessing inhibitory control. In the task, participants were seated in a comfortable desk chair behind a personal computer of which the screen was placed at approximately 60 cm distance.

Impulsivity and response inhibition in alcohol dependence and problem gambling [PDF]

, 2009
INTRODUCTION: Impulsivity is a central feature of drug addiction and may arise as a result of impaired inhibitory control. The extent to which inhibitory deficits arise as a consequence of drug exposure or relate to pre-existing addiction vulnerability ...

Working Memory Load Selectively Influences Response Inhibition in a Stop Signal Task

, 2021
Inhibitory control is a key executive function and has been studied extensively using the stop signal task. By applying a simple race model that posits an independent race between a GO process responsible for initiation of responses and a STOP process ...

On the interplay between state-dependent reconfigurations of global signal correlation and BOLD fluctuations: An fMRI study

NeuroImage
Background: The dynamics of global, state-dependent reconfigurations in brain connectivity are yet unclear. We aimed at assessing reconfigurations of the global signal correlation coefficient (GSCORR), a measure of the connectivity between each voxel ...

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Saliency Processing and Obesity: A Preliminary Imaging Study of the Stop Signal Task [PDF]

Obesity, 2012
Obesity has been associated with altered cerebral functions including cognitive control. The stop signal task (SST) has been widely used to study cognitive control by producing high conflict stop trials among many low conflict go trials. Contrasting these stop trials with go trials provides a measure of saliency processing and response inhibition.

Stop-signal anticipation task

The Stop-signal anticipation task aims to measure performance during actual stopping as well as during the anticipation of stopping. Trials begin with the presentation of a cue (0, * or **), representing the stop-signal probability (0, 22 and 33 ...

Stimulus-response mappings shape inhibition processes: a combined EEG-fMRI study of contextual stopping.

PLoS ONE, 2014
Humans are rarely faced with one simple task, but are typically confronted with complex stimulus constellations and varying stimulus-relevance in a given situation.

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

Molecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...
