Neuroimaging reveals prefrontal cortex and cingulate cortex are key for executive control of conscious actions. It remains unclear if a single system governs both implicit and explicit processes.

Area of Science:

  • Neuroscience
  • Cognitive Neuroscience

Background:

  • Executive control of conscious actions involves prefrontal and cingulate cortices.
  • These brain regions are crucial for regulating willed actions.

Purpose of the Study:

  • To investigate the role of prefrontal cortex in executive control.
  • To determine if executive control mechanisms for implicit and explicit processes overlap.

Main Methods:

  • Neuroimaging studies were used to identify active brain areas.
  • Analysis focused on tasks involving willed actions and implicit processes like motor learning and priming.

Main Results:

  • Prefrontal and cingulate cortices are consistently implicated in executive control.
  • Implicit tasks, such as motor sequence learning, activate similar prefrontal areas as willed actions.

Conclusions:

  • Prefrontal cortex may be involved in the initial stages of executive control.
  • Further research is needed to ascertain if a unified or distinct executive control system manages implicit and explicit processes.
