Figure 4.

Spontaneous synaptic currents from identified myelinated A‐, Ah‐ and unmyelinated C‐type baroreceptive neurons of nucleus tractus solitarius (NTS). Baroreceptive modality was verified by the fluorescence around the neurons through aortic depressive nerve (ADN) labeling with Dil; baroreceptive fiber type was identified by capsaicin (Cap) and delay excitation; (A‐C) representative recordings of myelinated A‐type (Cap‐insensitive, without delay excitation), myelinated Ah‐type (Cap‐insensitive, with slight delay excitation), and unmyelinated C‐type (Cap‐sensitive, with dramatic delay excitation), respectively; (D), three examples of spontaneous synaptic currents from A‐type baroreceptive neurons; (E), three examples of spontaneous synaptic currents from Ah‐type baroreceptive neurons; (F), three examples of spontaneous synaptic currents from C‐type baroreceptive neurons. Scale bars in (C) also applied for (A) and (B); scale bars in (F) also applied for other spontaneous synaptic current recordings
