>> MIDBRAIN ACTIVATION

The midbrain is the smallest region of brain that acts as a sort of relay station for auditory and visual information.The midbrain is located above the brain stem of human beings. It is responsible for the perception of stimuli and the subsequent communication with the right and left hemispheres to process this perceptive information. Typically, as part of the lower brain centres, the midbrain is not subject to an individuals conscious awareness.
Dr Makato Shichida who devoted more than 40 years of research into the functioning og brain, actually uses term "interbrain" rather than "Midbrain".
