AbstractEvidence from neurophysiological and genetic studies demonstrates that activity sparsity, the proportion of neurons that are active at a given time in a population, systematically varies across the canonical trisynaptic circuit of the hippocampus. Recent work has also shown that sparsity varies across the hippocampal dorsoventral (long) axis, wherein activity is sparser in ventral than dorsal regions.
