The paper identifies two types of hippocampal theta sequences in rats during memory-guided navigation and describes a circuit mechanism for goal-directed sweeps.

This study examines how critical dynamics in the hippocampus shift during learning and sleep to support cognitive functions.

The paper investigates how interictal epileptiform discharges (IEDs) affect memory in Alzheimer's Disease mice, finding that IEDs disrupt hippocampal activity and correlate with impaired memory.

The paper identifies specialized hippocampo-cortical subcircuits that organize memory encoding, routing, and replay through distinct pyramidal cell subpopulations.

This study shows that prenatal alcohol exposure disrupts hippocampal sharp-wave ripple spike dynamics, potentially contributing to memory deficits.

This study investigates how moderate prenatal alcohol exposure affects hippocampal place cell firing and theta rhythmicity in adult rats, finding reduced spatial tuning and context sensitivity.

This study assesses spatial navigation in TgF344-AD rats using the Morris water task, finding impaired directional and spatial precision in older rats without procedural task deficits.
