Activation of CA3 neurons by optogenetic stimulation of mossy fiber
... Despite extensive studies in in vitro preparations, it is unclear whether and how discharges of dentate gyrus (DG) granule cells shape spatial firing of CA3 neurons in behaving animals. To investigate effects of DG granule cell inputs on CA3 neural activity in vivo, we injected Credependent virus ca ...
