The morphology of trigeminal nociceptive neurons in the caudal bulbar lateral reticular formation of the cat.
Two types of trigeminal nociceptive neurons, i.e. subnucleus reticularis ventralis (SRV) and wide dynamic range (WDR) neurons were identified in the caudal bulbar lateral reticular formation (LRF) and intracellularly stained with horseradish peroxidase. SRV neurons were large neurons characteristic of the subnucleus reticularis ventralis. Their dendrites were confined to the LRF. WDR neurons were situated in the subnucleus reticularis dorsalis. Their dendrites penetrated into the magnocellular layer, but did not reach the substantia gelatinosa.
