Differential distribution of four types of tooth pulp neurons in the caudal medulla oblongata of the cat.
The medulla oblongata caudal to the obex was explored for neurons responsive to tooth pulp (TP) stimulation in cats. Four different classes of TP neurons were found. They were TP specific neurons, trigeminal wide dynamic range neurons with TP input, trigeminal subnucleus reticularis ventralis (SRV) neurons with TP input and convergent reticular formation with TP input. They were differentially distributed within the caudal medulla oblongata.
