The hippocampus is one of the brain regions involved in cognitive
functions, including learning and memory. Extensive studies have
unveiled how information is processed within this system. However, the
mechanisms by which hippocampal activity is translated into action
remain unsolved. One important target of hippocampal projections is the
nucleus accumbens, which has been described as the motivation-to-action
interface. Previous experiments indicate that these projections can
control information processing in this region by setting neurons into a
depolarized state. Here, we report that membrane potential transitions
in nucleus accumbens neurons are correlated with electrical activity in
the ventral hippocampus, suggesting that hippocampal neural activity
can determine ensembles of active accumbens neurons.
