Response inhibition or salience detection in the right ventrolateral prefrontal cortex?
This study addresses the question of whether frontal activation in response-inhibition tasks is specifically associated with the suppression of a motor response. An alternative model suggests a role in the detection of behaviorally relevant or salient events. For this purpose, we used functional MRI...

| Summary: | This study addresses the question of whether frontal activation in response-inhibition tasks is specifically associated with the suppression of a motor response. An alternative model suggests a role in the detection of behaviorally relevant or salient events. For this purpose, we used functional MRI with an auditory go/no-go paradigm. This paradigm allowed the disentangling of inhibition-related from salience-related effects, which were associated with different frontal regions. Importantly, the right ventrolateral prefrontal cortex consistently showed sensitivity for salience but not for inhibition requirements. This reflects a more general salience-detection mechanism, which is not specific for response-inhibition tasks. |
