| burst LTS neuron | Hoffman et al. (HTD) | The third type of neuron encountered in this region conformed with type-III criteria (Tasker and Dudek, '91). They were referred to as bursting LTS cells since they invariably had large LTS potentials that generated bursts of three or more NA+ spikes. They also displayed strong inward rectification in response to hyperpolarizing current pulses (fig. 5B). | partial correspondence | | LTSs with variable shapes and amplitudes, ranging from small-amplitude'humps' to long-lasting plateaus, were observed in 35/41 (84%) type A, 20/20 (100%) type B and 15/18 (85%) type C neurones. The incidence of LTSs was not significantly different among neuronal types. | Stern J.E. | Mihail Bota |

| preautonomic neuron vagal complex | Swanson (Swanson) | Cell counts showed that an average of 653 neurons was labeled in the PVH after true blue injections involving the dorsal vagal complex in three animals.Collator note: these cells are defined on the basis of projections to the parasympathetic autonomic centers located in the dorsal vagal complex. See Figure 6 for distributions of the preautonomic neurons. | is included | | The tracer[...] was pressure-injected unilaterally (100–200 nl) into the dorsal vagal complex (DVC) at the level of the obex, which included the NTS and the DMX (Fig. 1A). . As verified histologically [...], this tracer injection protocol reliably labelled PVN neurones in the ventral parvocellular (PaV) and posterior parvocellular (PaPo) subnuclei of the PVN (see Fig. 1B).Collator note: it is possible that some of preautonomic neurons that send projections to the spinal cord are of this morphological type. | Stern J.E. | Mihail Bota |

| non-bursting LTS neuron | Hoffman et al. (HTD) | Another PVN neuronal population was composed of non-bursting LTS cells; these conformed with type-II electrophysiological criteria (Tasker and Dudek, '91) by having relatively small low-threshold potentials that usually generated only one or two action potentials (Fig. 3A). Also consistent with this classification, non-bursting LTS cells were more heterogeneous in their electrophysiological properties than the other two cell types. Thus non-bursting LTS neurons displayed I-V relations that were linear or
weakly nonlinear (Fig. 3B). Of nine non-bursting LTS neurons recorded in this study, none stained positively for neurophysin (Fig. 4). Collator note: compare Fig 9b, c with Atlas levels 25 and 26, respectively. | partially corresponds | | LTSs with variable shapes and amplitudes, ranging from small-amplitude'humps' to long-lasting plateaus, were observed in 35/41 (84%) type A, 20/20 (100%) type B and 15/18 (85%) type C neurones.
