Brain Areas involved
sensorimotor hierarchy
- Posterior parietal Directing behavior by
association cortex providing spatial information
Direct attention (integration about original
position of body parts and position of
external object)
Lies posterior in parietal lobe
Sends to
o Dorsolateral prefrontal association
cortex
o Secondary motor cortex
o Frontal eye field (control of eye
movement)
Input from
o Visual system
o Auditory system
o Somatosensory system
- Dorsolateral Evaluation of external stimuli
prefrontal Initiation of voluntary reaction (command for
association cortex movement)
Sends to
o Areas of secondary motor cortex
o Primary motor cortex frontal eye field
o Back to posterior parietal association
cortex
Input from
o Posterior parietal association cortex
- Secondary motor Programming specific patterns of movement after
cortex instruction from dorsolateral prefrontal cortex
Four parts
1. Supplementary motor area (top of
frontal lobe)
learning and performing sequences
of movement
2. Premotor cortex (from under sup.. till
lateral fissure)
Visually guided tasks and
movement plan in terms of location of
stimulus and hand
Learning and executing behavior
that is guided by sensory information
3. Two cingulate motor areas
Sends to
o Primary motor cortex
Input from
o Both association cortex
o Mirror Part of secondary motor cortex
neurons Fire when goal direction action is performed
