Precentral Sulcus Lesions

Precentral sulcus lesions can lead to various neurological issues, affecting movement and sensation. Understanding the causes, symptoms, diagnosis, and treatment options is crucial for managing these conditions effectively.

The precentral sulcus is a groove in the brain’s surface, specifically in the frontal lobe, responsible for motor function. Lesions in this area can disrupt normal brain function, leading to movement problems.
