Go-NoGo fMRI paradigm
Unreviewed
The computerized task consists of 240 trials in which participants see a stimulus printed on the screen and they are asked to vary their response according to the stimulus color. In the more frequent 180 “Go” trials, participants are instructed to respond by pressing a button when they see green text on the screen displaying the word “press.” The main dependent behavioral measures in Go-NoGo tasks are response time and the commission error rate (making an incorrect “Go” response on “No-Go” trials); fewer commission errors signify better response inhibition. The Go-NoGo fMRI paradigm utilizes this same task to measure activation of participants’ cognitive control circuit (dorsolateral prefrontal cortex, anterior cingulate cortex, dorsal parietal cortex [DPC], and posterior cingulate gyrus), as well as the functional connectivity among these regions.

No associations have been added.Behaviors
No associations have been added. CONDITIONS
Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.
CONTRASTS
In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.
INDICATORS
No indicators have yet been associated.
An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).
