mid·brain

(mĭd′brān′)
The middle part of the brain in vertebrate animals. In most animals except mammals, the midbrain processes sensory information. In mammals, it serves mainly to connect the forebrain with the hindbrain. Compare forebrain, hindbrain.

BOISE, Idaho, February 13, 2016 -- While scientists are unsure of the molecular causes of Parkinson's disease, they do know the disorder's tremors and other motor dysfunctions are linked to a loss of dopaminergic neurons located in the substantia nigra, a structure in the midbrain.
