4. Inner Structures of Brain
The inner parts of the brain include the deep structures within the cerebrum (like the thalamus, hypothalamus, basal ganglia, hippocampus, amygdala), the cerebellum (coordination/balance), and the brainstem (midbrain, pons, medulla) controlling vital functions, all connected by white matter and protected by cerebrospinal fluid within ventricles, crucial for relaying signals and managing complex processes. -PKK
