The paper identifies evolutionarily conserved cell types in the granular retrosplenial cortex across mice and rats, despite differences in marker genes.

The paper identifies a distinct RSG neuron subtype, LR neurons, that lacks persistent firing in response to cholinergic agonists, enabling consistent angular head velocity computation across brain states.

The paper shows that expanding immature adult-born dentate granule cells in mice enhances GABAergic inhibition and improves social memory consolidation.

This paper shows that a single dose of 25CN-NBOH improves cognitive flexibility in mice weeks later, using a complex reversal learning task.

This study shows that psychedelics suppress intrinsic excitability of prefrontal pyramidal neurons via M-current channels, independent of 5-HT2AR activation, and reduces working memory timespan.

This study identifies parallel circuits in the granular retrosplenial cortex that process spatial and non-spatial information through distinct neuronal subtypes.

The paper introduces a new silicon-based micro-fabrication technology for creating high-density neural micro-probe arrays with thousands of electrodes, achieving a record density of 400 electrodes/mm2 in rat brain recordings.

The paper shows that postrhinal theta oscillations have differential encoding of running speed through amplitude and waveform shape, with distinct behavioral correlates.

The paper identifies a unique cell type in the retrosplenial cortex that supports precise and persistent information encoding through its intrinsic properties.
