The visual system and the somatosensory system are active even during resting state fMRI Activation and response in the sensory nervous system. The sensory nervous system is a part of the nervous system responsible for processing sensory information.
Each posterior communicating artery is situated within the interpeduncular cistern, superolateral to the pituitary gland. [2]: 450 Each are is situated upon the medial surface of the ipsilateral cerebral peduncle [1]: 477 and adjacent to the anterior perforated substance.

An area at the entrance to the lateral sulcus, adjoining the primary somatosensory cortex (S1), is called the parietal ventral (PV) area. Posterior to PV is the secondary somatosensory area (area S2, which must not be confused with " region S2" which designates the entire secondary somatosensory cortex, of which area S2 is a part).
The ventral tegmental area (VTA) (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, [1] or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain.
