Successful response inhibition relies on both automatic and controlled processes. Neurophysiological data reveal distinct "stimulus" and "response selection" codes, with the latter predicting behavior and linked to parietal brain regions.
Area of Science:
- Cognitive Neuroscience
- Neuropsychology
- Electrophysiology
Background:
- Response inhibition is crucial for goal-directed behavior.
- Inhibitory control is modulated by automatic response tendencies and cognitive control.
- Cognitive theories propose stimulus-response translation codings, but their neurophysiological basis is unclear.
Purpose of the Study:
- To investigate the neurophysiological underpinnings of conjoint automatic and controlled processes in response inhibition.
- To determine if cognitive codes for stimulus-response translations are reflected in brain activity.
- To identify neuroanatomical structures involved in processing these codes.
Main Methods:
- Applied temporal decomposition of electroencephalography (EEG) data.
- Utilized source localization techniques to identify brain regions.
- Analyzed neurophysiological codes during response inhibition tasks.
Main Results:
- Identified distinct, intermingled neurophysiological codes: "stimulus codes" and "response selection codes".
- "Response selection codes" predicted behavioral performance and were conjointly modulated by automatic and controlled processes.
- These modulations were associated with activity in the inferior and superior parietal areas (BA40/BA7).
Conclusions:
- Cognitive concepts of stimulus-response coding have neurophysiological analogues.
- Response selection codes, modulated by automatic and controlled processes, are critical for behavioral control.
- Inferior and superior parietal regions likely play a role in updating internal representations for complex information processing during inhibition.
