Brain herniation occurs when increased pressure causes brain tissue protrusion through rigid barriers. Types include transtentorial, subfalcine, central, upward transtentorial, and tonsillar herniation. Transtentorial herniation affects medial temporal lobe under tentorium. Subfalcine herniation pushes cingulate gyrus under falx cerebri. Central herniation involves both temporal lobes through tentorial notch
