TL;DR: Observations provide evidence that glutamate is a neurotransmitter in lamina I TSTT terminals in the nucleus submedius and suggest glutamatergic neurotransmission between cortical afferents and nucleusSubmedius neurons.

TL;DR: The possibility that specific thermoreceptive and nociceptive influences on sympathetic outflow are conveyed directly to spinal sympathetic regions by lamina I neurons was investigated anatomically with the immunofluorescent PHA‐L technique in the cat and the cynomolgus monkey.

TL;DR: The location of the ascending axons of spinal lamina I cells was studied in cats that received injections of Phaseolus vulgaris leucoagglutinin in the superficial dorsal horn of the cervical or lumbosacral enlargement to support previous descriptions of a dorsoventral distribution of STT axons according to laminar origin, but they contradict recent reports that lamin I axons ascend in the dorsolateral funiculus.

TL;DR: The nocturnal owl monkey has a specialized perinasal thermoreceptive trigeminothalamic sensory pathway that is probably of behavioral significance during olfactory sniffing and corroborate other findings that have indicated that lamina I COLD cells are pyramidal neurons and are not physiologically modulated by substance P or serotonin.

TL;DR: The results indicate that both horseradish peroxidase and fluorescent tracers may be selectively transported and, thus, that the cautious use of both methods should be recommended for analyses of afferent populations.
