Electrical coupling between pairs of dentate gyrus (DG) basket cells in young (P14) and adult (P28 and P42) mice.A, IR-DIC (top) and fluorescence microscopy image (bottom) of an EGFP-positive dentate gyrus basket cell showing the typical morphology. B, Light microscopic image of a biocytin-filled, EGFP-positive pair of dentate gyrus basket cells. C, Firing patterns of basket cells from a P14 and P42 brain that were electrically coupled. The voltage response of cell 1 after current injection
