Application of cholinergic agonists to slices causes persistent firing in GIN cells. A: persistent firing during carbachol application in a GIN cell. B: instantaneous firing rate during trace in A. C: during carbachol application, 94.4% of GIN cells fired (n = 17/18), and no RS cells did (0/4). FS cells were not tested with carbachol. Similarly, 100% of tested GIN cells (n = 9/9) fired in response to application of the muscarinic agonist, muscarine; no RS cells did (n = 0/1) and FS cells were not tested with muscarine. D: during application of carbachol, firing in strongly electrically coupled GIN cells was synchronous. E: cross-correlogram of 4 min of firing in GIN cells during carbachol application, from which D is a sample. Bin width was 20 ms.
