What are the major areas of the parietal lobe?

What are the major areas of the parietal lobe?

The following are some key areas of the parietal lobe:

• Somatosensory cortex. The somatosensory cortex in the front part of the parietal lobe resides in two areas: the postcentral gyrus and the posterior paracentral lobule. ...
• Superior parietal lobule. ...
• Super marginal gyrus. ...
• Angular gyrus.

What are the two parts of the parietal lobe called?

Thus the parietal lobe can be further divided into the left and right parietal lobes. The parietal lobe rests near the top and center of the cerebral cortex, just behind the frontal lobe and above the occipital and temporal lobes.

What are the main job of the parietal lobe?

Function. The parietal lobe is vital for sensory perception and integration, including the management of taste, hearing, sight, touch, and smell. It is home to the brain's primary somatic sensory cortex (see image 2), a region where the brain interprets input from other areas of the body.

What does the parietal lobe contain?

The parietal lobes contain the primary sensory cortex which controls sensation (touch, pressure). Behind the primary sensory cortex is a large association area that controls fine sensation (judgment of texture, weight, size, and shape).

What role does the parietal lobe play in visual remapping?

Frontal and parietal cortices appear to have complementary roles in remapping. Patients with lesions in frontal or parietal cortex show different kinds of deficits in the double-step task. Parietal cortex seems to be essential for spatial representation while frontal cortex is more important for motor control.

What part of the head is parietal?

parietal bone, cranial bone forming part of the side and top of the head. In front each parietal bone adjoins the frontal bone; in back, the occipital bone; and below, the temporal and sphenoid bones. The parietal bones are marked internally by meningeal blood vessels and externally by the temporal muscles.

What is the function of the medulla oblongata?

The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration.

What part of the brain controls memory?

hippocampus Most available evidence suggests that the functions of memory are carried out by the hippocampus and other related structures in the temporal lobe. (The hippocampus and the amygdala, nearby, also form part of the limbic system, a pathway in the brain (more...)

What is the role of the parietal lobe in attentional processing?

The human parietal lobe (Figure 1a) was traditionally labeled as an association cortex, appearing to play a role in the processing of sensory information, including perception, decision making, numerical cognition, integration, speech comprehension, and spatial awareness (Critchley 1953).
