The document discusses the brainstem, which consists of the midbrain, pons, and medulla. It refers to a previous lecture on brain lesion localization and includes information on subcortex and internal capsule in the presentation. The lecture on brainstem lesions builds upon earlier concepts introduced by Prof. Dr. Bashir Ahmed Dar.

12. Brainstem
• Brainstem comprises of Midbrain, Pons and Medulla
• Lecture on brainstem lesion is actually a continuation
of my previous lecture named "Localization of brain
lesion by Prof Dr Bashir Ahmed Dar Sopore Kashmir"
• Therefore I have included subcortex and internal
capsule also in this slide presentation
