This page covers biological details of component group Premotor Cortex. Component group is part of aHuman target integrated biological model.

• Top-down path to center: Cerebral Cortex -> Anterior Lobe (NC.LOBE.ANT) -> Premotor Cortex (NC.PMC) (see Mind Maps)
• Function: Selection of appropriate motor plans for voluntary movements

Component items:

• Frontal Eye Field (NMA.NC.PMC.FEF): Initiation of eye movements
  • Caudal Frontal Eye Field (NMA.NC.PMC.CFEF): Head and eye movements toward visual stimuli
  • Anterior Frontal Eye Field (NMA.NC.PMC.AFEF): Head and eye movements toward auditory stimuli
• Dorsal Premotor Cortex (MCA.NC.DPMC)
  • Dorsal Caudal Premotor Cortex (NMA.NC.PMC.F2): Guiding reaching
  • Dorsal Rostral Premotor Cortex (NMA.NC.PMC.F7): Associate arbitrary sensory stimuli with specific eye movements
• Ventral Premotor Cortex (MCA.NC.VPMC)
  • Ventral Caudal Premotor Cortex (NMA.NC.PMC.F4): Sensory guidance of movement
  • Ventral Rostral Premotor Cortex (NMA.NC.PMC.F5): Shaping hand during grasping
