Spatially confined dopamine from locus coeruleus axons selectively shapes hippocampal dynamics and action timing

The paper shows that localized dopamine from locus coeruleus axons selectively enhances specific hippocampal neurons during navigation, delaying action timing and improving reward anticipation.

A scalable hippocampal code for flexible interval timing through persistent activity

The paper identifies a new hippocampal neuron subpopulation that supports flexible interval timing through persistent activity and temporal scaling.

Two-Phase Coding Strategy by CA1 Pyramidal Neurons: Linking Spatiotemporal Integration to Predictive Behavior

The paper identifies a two-phase neural code in hippocampal CA1 pyramidal neurons that encodes time and distance, linking spatiotemporal integration to predictive behavior.

Time or distance encoding by hippocampal neurons with heterogenous ramping rates

This study identifies two subpopulations of hippocampal neurons that encode distance or time through distinct coding mechanisms, revealing roles for SST and PV interneurons in integration and reset processes.
