Effects of L-054,264, a selective sst_2A agonist, on K⁺ and Ca²⁺ channel currents in DA amacrine cells in TH–RFP retinal slices. A, Outward I_K recording from a DA amacrine cell in the absence (left) and presence (right) of L-054,264 (1 μm). B, Mean I–V relationships for I_K in the absence (black) and presence (red) of L-054,264. C, Inward I_Ca in the absence (left) and presence (right) of L-054,264. D, Mean I–V relationships for I_Ca in the absence (black) and presence (red) of L-054,264. Recordings were made in the presence of TTX (500 nm). Voltage command protocol is shown below the current trace. n = 5–6 cells per group. *p < 0.05.
