      abstract     = {How the coordination of neuronal spiking and brain rhythms
                      between hippocampal subregions supports memory function
                      remains elusive. We studied the interregional coordination
                      of CA3 neuronal spiking with CA1 theta oscillations by
                      recording electrophysiological signals along the
                      proximodistal axis of the hippocampus in rats that were
                      performing a high-memory-demand recognition memory task
                      adapted from humans. We found that CA3 population spiking
                      occurs preferentially at the peak of distal CA1 theta
                      oscillations when memory was tested but only when previously
                      encountered stimuli were presented. In addition, decoding
                      analyses revealed that only population cell firing of
                      proximal CA3 together with that of distal CA1 can predict
                      performance at test in the present non-spatial task.
                      Overall, our work demonstrates an important role for the
                      synchronization of CA3 neuronal activity with CA1 theta
                      oscillations during memory testing.},
