Precuneus Lobule Lesions

The precuneus lobule is a part of the brain located in the parietal lobe, towards the back of the head. It plays a crucial role in various cognitive functions, including memory retrieval, visuospatial processing, and self-awareness. Lesions in the precuneus lobule refer to abnormal changes or damage to this specific brain region, which can disrupt its normal functioning and lead to neurological symptoms.

14. Functional MRI (fMRI)
15. Brain biopsy? (in cases of suspected tumor)
16. Lumbar? puncture (to assess for infection? or pain?, swelling?, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation?)
