2023年1月8日 · Your parietal lobe is a processing center for sensations you can feel with your sense of touch. These include temperature (hot and cold), pressure, vibration and pain. Self-perception also uses your sense of touch to tell you where parts of your body are without needing to see them (the technical term for this is “ proprioception ”).
Parietal Lobe Damage: Understanding Symptoms and …
2022年11月29日 · Parietal lobe damage may limit your ability to process sensory information and create difficulty with spatial awareness. This can include deficits such as poor proprioception, impaired vision, speech difficulties, and even hemineglect. Additionally, parietal lobe damage can result in disorders such as Balint’s syndrome or Gerstmann’s syndrome.

Parietal Lobe - an overview | ScienceDirect Topics
The parietal lobes are involved with opposite-side sensation, movement, and visual association. As with frontal lobe lesions, lesions of the parietal lobes can reach impressive size before becoming symptomatic. The parietal lobes are indeed not closely associated with the circle of Willis or the skull base and cranial nerves.
