What is intraparietal sulcus?

What is intraparietal sulcus?

The intraparietal sulcus together with the postcentral sulcus, is one of the two main sulci of the parietal lobe. It runs from the post-central sulcus towards the occipital pole, dividing the lateral parietal lobe into the superior and inferior parietal lobules.

What does the intraparietal sulcus separate?

The intraparietal sulcus (IPS) is located on the lateral surface of the parietal lobe, and consists of an oblique and a horizontal portion….

What is the function of intraparietal sulcus?

Different subregions or areas of the intraparietal sulcus are involved in the planning of eye movements, grasping movements, reaching, and defensive forelimb and head movements. Sensory guidance is based on somatosensory, visual, and, to a lesser extent, auditory inputs.

What does Intraparietal mean?

Definition of intraparietal 1 : intramural sense 2. 2 : located within the parietal lobe of the cerebrum.

Where is the anterior intraparietal area?

It has been shown in nonhuman primates that the posterior parietal cortex is involved in coordination of arm and eye movements in space, whereas the anterior intraparietal area in the anterior lateral bank of the intraparietal sulcus plays a crucial role in fine finger movements, such as grasping.

What is the function of the superior temporal sulcus?

The superior temporal sulcus (STS) is the chameleon of the human brain. Several research areas claim the STS as the host brain region for their particular behavior of interest. Some see it as one of the core structures for theory of mind. For others, it is the main region for audiovisual integration.

What is the somatosensory strip?

The Somatosensory and Motor Cortex! Logically placed between the parietal lobes and our frontal lobes (the executive), are two strips called the somatosensory cortex and the motor cortex (see right). The somatosensory cortex coordinates the sensory data that comes up from all over the body.

Is the insula in the DLPFC?

The SN is involved in detecting, integrating and processing internal and external salient information, and it includes the dorsal anterior cingulate cortex (dACC), anterior insula, amygdala, and ventral striatum (Seeley et al., 2007). The left DLPFC and anterior insula are the key nodes of the CEN and SN, respectively.

What are the anterior posterior and inferior boundaries landmarks for the precuneus?

The precuneus is limited anteriorly by the marginal branch of the cingulate sulcus, posteriorly by the medial portion of the parieto-occipital fissure and inferiorly by the subparietal (i.e. postlimbic) sulcus.

What is the posterior parietal cortex?

Posterior parietal cortex is a region of the brain that has been implicated in spatial attention and eye movements. In humans, lesions of the parietal lobe cause patients to ignore sensory stimuli located in the contralateral half of space, a phenomenon known as neglect.
