Visuomotor functions of the posterior parietal cortex
This special issue explores the posterior parietal cortex's (PPC) role in visuomotor control, synthesizing research from multiple methods. It covers primate studies, human imaging, and lesion data, highlighting key debates in the field.
Area of Science:
- Neuroscience
- Cognitive Neuroscience
- Primate Neurophysiology
Background:
- The posterior parietal cortex (PPC) is crucial for visuomotor control, integrating visual information with motor commands.
- This special issue compiles diverse research on the PPC's function in visuomotor tasks.
- Expert contributions cover a broad spectrum of methodologies, including physiology, anatomy, and human studies.
Discussion:
- Discussions address homologies between monkey and human parietal regions.
- The role of coordinate transformations in visuomotor control is examined.
- Controversial topics and recent advances in PPC research are reviewed.
Key Insights:
- The PPC is central to translating visual perception into goal-directed actions.
- Comparative studies reveal conserved and divergent functions across species.
- Advanced neuroimaging and stimulation techniques are refining our understanding of PPC circuitry.
Outlook:
- Future research directions will likely focus on detailed neural mechanisms of spatial representation and action planning.
- Investigating the PPC's role in complex, real-world visuomotor behaviors remains a key objective.
- Understanding PPC dysfunction may offer insights into neurological disorders affecting motor control.

Motor and Sensory Areas of the Cortex
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.
Association Areas of the Cortex
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...
