演 題:“Dopaminergic memory modulation by two distinct novelty systems“

要 旨: Most everyday memories may form automatically in the hippocampus. The key role of this memory system is to filter our unnecessary information, but keep the important memories by a mechanism that involves novelty-associated dopamine release in the hippocampus. Recent our studies revealed that projections from neurons in the locus coeruleus to the hippocampus can drive the environmental novelty-associated enhancement of memory retention through non-canonical release of dopamine in the hippocampus. These studies also raise a possibility that the impact of environmental novelty may differ from that of reward-associated novelty, and projections from neurons in the ventral tegmental area to the hippocampus might mediate reward-associated novelty which modulates the memory retention with a narrow time window.
