The paper introduces a wireless platform for recording and manipulating neural activity in small animals during natural behaviors.

This study shows AgRP neuron activity in mice tracks spatial proximity to food during foraging and recalls food locations after removal.

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 identifies large sharp-wave ripples (SWRs) that enhance memory reactivation and consolidation in mice by improving hippocampal and prefrontal cortex coordination during sleep.

This study shows that the hippocampus enables rapid generalization in mice through disentangled memory representations and structured circuit dynamics.

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

This study shows that real-time optogenetic silencing of hippocampal CA2 neurons reduces seizures, interictal EEG abnormalities, and social comorbidities in mouse models of temporal lobe epilepsy.

This study shows that CA2 ripples during sleep replay social exploration experiences, and disrupting or enhancing these ripples affects social memory consolidation.

The paper examines the proximodistal organization of the CA2 hippocampal area in rats, finding distinct synaptic and membrane potential trends along this axis.
