Atropine blocks carbachol-induced responses. (A) Carbachol (100 μM) application induced outward current in a tectal cell (top trace). A second application of carbachol in the presence of atropine (2 μM) elicited a minimal response in this same cell. (B) A carbachol-induced increase in sPSCs (top trace) was prevented by the presence of atropine (bottom trace). Solid line indicates the time during which carbachol (cch) was applied; dotted line, the time during atropine was present. The interval between the beginning of the first and second applications of carbachol in both A and B was 5 min.
