Thermoreceptive lamina I trigeminothalamic neurons project to the nucleus submedius in the cat

Exp Brain Res. 1991;85(2):470-4. doi: 10.1007/BF00229424.


The technique of antidromic mapping with a roving array of electrodes was used to demonstrate that lamina I trigeminothalamic cells responsive specifically to skin temperature project to the n. submedius (Sm) in the medial thalamus of the cat. This finding indicates that Sm receives thermoreceptive in addition to nociceptive information.
