What does the posterior part of the brain control?

The posterior parietal cortex (the portion of parietal neocortex posterior to the primary somatosensory cortex) plays an important role in planned movements, spatial reasoning, and attention.

What is the main function of the posterior parietal cortex?

The posterior parietal cortex plays a key role in spatial representation of objects for action planning and control. Primate neurophysiology studies suggest that the posterior parietal cortex receives multimodal sensory inputs and transforms the information from sensory-based coordinates to effector-based coordinates.

Is the posterior part of the cerebral cortex?

Posterior cortex usually means the posterior (back) part of the complete cerebral cortex and includes the occipital, parietal, and temporal cortices. In other words, the posterior cortex includes all the cerebral cortex without the frontal cortex.

What does the PPC do in the brain?

New research by neuroscientists at the University of Chicago shows that the posterior parietal cortex (PPC), an area of the brain often associated with planning movements and spatial awareness, also plays a crucial role in making decisions about images in the field of view.

What is the most posterior part of the brain?

Occipital Lobe: most posterior, at the back of the head; the occipital lobe controls sight.

What is the function of the posterior association area?

The posterior association area is where visual, auditory and somatosensory association areas meet. This is what gives us our spatial awareness of our body. It is the kinesthetic sense that is very strong in professional dancers or athletes for example.

Where is the posterior association area located?

posterior parietal lobe
The posterior association area is located in the posterior parietal lobe, and it also extends into the occipital and temporal lobe. The somatosensory stimuli from the parietal lobe, the visual stimuli from the occipital lobe, and the auditory stimuli from the temporal lobe all meet in the posterior association area.

Where is the posterior of the brain?

The posterior parietal cortex, along with temporal and prefrontal cortices, is one of the three major associative regions in the cortex of the mammalian brain. It is situated between the visual cortex at the caudal pole of the brain and the somatosensory cortex just behind the central sulcus.

What are the posterior part of the body?

Posterior (or dorsal) Describes the back or direction toward the back of the body. The popliteus is posterior to the patella. Superior (or cranial) describes a position above or higher than another part of the body proper.

Where is the posterior association area?

Is the parietal lobe posterior to the central sulcus?

The parietal lobe is posterior to the central sulcus and above the lateral sulcus. Its posterior boundary is the parieto-occipital sulcus, which is only visible from the medial aspect of the cerebral hemisphere. The parietal lobe is concerned with somatosensory and visuospatial perception. It has lateral and medial surfaces.

Where is the postcentral gyrus located in the brain?

The postcentral gyrus is immediately posterior to the central sulcus, behind and parallel to the motor strip. It corresponds to the primary somatosensory cortex ( BA 3, 1 and 2 ).

Where does semi automatic movement take place in the parietal cortex?

Certain semi-automatic movements are initiated by projections from the parietal cortex to the lateral premotor area ( Clinical Box 3.3 ). The inferior parietal lobule is a multimodal association area which lies at the junction of the visual, auditory and somatosensory cortices.

Where is the mental space in the brain?

“mental space” in the posterior parietal cortex. Cortical regions immediately posterior to the central sulcus are largely involved in: processing somatosensory information.
