burst LTS neuronHoffman 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 complexSwanson (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 neuronHoffman 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
