Displacement of brain tissue under the falx cerebri or through the tentorial notch of the tentorium cerebelli is termed and occurs with elevated icp in one brain compartment with displacement of cerebral tissue toward an area of pressure.

Brain herniation is displacement of brain tissue under the falx cerebri under the area of less pressure.

Explanation:

Brain herniation is disorder it occur due to the displacement of the cerebra in the brain.  It is potentially deathly disorder when brain affected by high temperature or squeezing of the brain across the structure.

The tentorium is the dual fold in the brain, then it  is an extension of the dura matter that separates cerebellum from cerebrum. There are two major types of herniation in the brain; that is supratentorial and infratentorial. The supretentorial is seen above the Tentorial notch.
