Long-Term High Salt Intake Involves Reduced SK Currents and Increased Excitability of PVN Neurons with Projections to the Rostral Ventrolateral Medulla in Rats

Figure 1

Identification of PVN-RVLM neurons in brain slice for whole-cell patch clamp recording. (a) Red fluorescent tracers were microinjected (100 nL) into the RVLM. (b) Retrograde labeling of the ipsilateral PVN was observed in the dorsal and ventrolateral subnuclei. (c) Image viewed with fluorescence illumination shows a recorded PVN-RVLM neuron containing retrograde tracer. (d) Infrared-DIC image shows the patch electrode positioned on the same PVN-RVLM neuron as (c). 3V: third ventricle.
