The role of gap junctions in the neural control of fertility remains poorly understood. Using acute brain slices from adult GnRH-green fluorescent protein transgenic mice, individual GnRH neurons were filled with a mixture of fluorescent dextran and neurobiotin. No dye transfer was found between any GnRH neurons, although approximately 30% of GnRH neurons exchanged neurobiotin with closely apposed cells. Dual electrophysiological recordings from pairs of GnRH neurons revealed an absence of… CONTINUE READING
