The dorsal tegmental nucleus is located in the brain stem near the midline.
In rats, the DTN contains a small number of enkephalin, substance p, and glutamatergic neurons which project to mammillary.
[8] The pars centralis of the DTN receives input from the prepositus hypoglossi and the supragenualis nucleus.
[13][14][15][16] Some cells respond to changes in head movement in specific directions such as to the left, right, or both.
The firing activity of these cells are also affected by the speed of the movement of the head as well.
