Figure 1. NPS stimulates glutamatergic input in LA projection neurons.

Figure 1

(A) Examples of glutamatergic sEPSCs recorded in a LA projection neuron before and (B) during action of NPS. (C) Cumulative amplitude and (D) inter-event interval histograms obtained from the same neuron shown in (A, B) before addition of NPS and after a steady-state effect had been reached. (E) Normalized sEPSC amplitude and frequency pooled during control conditions and after addition of NPS demonstrates a significant increase in sEPSC amplitude as well as frequency. (F) Time course of NPS effect and input resistance for a representative PN. (G, H) Under current-clamp conditions, NPS application induces a depolarizing response associated with increased spike activity triggered upon depolarizing current injections in LA projection neurons. * P<0.05, ** P<0.01.
