No‐go dominant brain activity in human inferior prefrontal cortex revealed by functional magnetic resonance imaging
Abstract
We investigated the response inhibition function of the prefrontal cortex associated with the go/no‐go task using functional magnetic resonance imaging in five human subjects. The go/no‐go task consisted of go and no‐go trials given randomly with roughly equal probability. In go trials a green square was presented and the subjects had to respond by promptly pushing a button using their right or left thumbs, but in no‐go trials a red square was presented and subjects were instructed not to respond. When brain activity in no‐go trials is dominant over that in go trials in areas in the prefrontal cortex, this no‐go dominant brain activity would reflect the neural processes for inhibiting inherent response tendency. We used a new strategy of image data analysis by which transient brain activity in go or no‐go trials can be analysed separately, and looked for the prefrontal areas in which the brain activity in no‐go trials is dominant over that in go trials. We found the no‐go dominant foci in the posterior part of the right inferior frontal sulcus reproducibly among the subjects. This was true whether the right or left hand was used. These results suggest that this region in the prefrontal cortex is related to the neural mechanisms underlying the response inhibition function.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
