Sparsening and decorrelation of granule cell activity in the dentate gyrus by noradrenaline

This study shows that noradrenaline enhances feedforward inhibition in the dentate gyrus, leading to sparser and decorrelated granule cell activity, which supports memory formation.

VIP interneurons control hippocampal place cell remapping through transient disinhibition in novel environments.

The paper identifies VIP interneurons as regulators of hippocampal place cell remapping in novel environments through transient disinhibition and shows their role in spatial learning.

Representations of tactile object location in the retrosplenial cortex

This study identifies a population of neurons in the retrosplenial cortex that encode tactile object location in a spatial reference frame, showing task- and context-dependent responses and memory traces.

Diverse long-range projections convey position information to the retrosplenial cortex.

The paper identifies which brain regions send position information to the retrosplenial cortex using two-photon axonal imaging in mice.

Cell-type-specific silence in thalamocortical circuits precedes hippocampal sharp-wave ripples.

The paper investigates how thalamocortical circuits in the retrosplenial cortex process hippocampal sharp-wave ripples, finding reduced inhibition and subcortical input before SWR events.

Parvalbumin interneuron dendrites enhance gamma oscillations

The paper investigates how dendrites of parvalbumin basket cells influence gamma oscillations through low dendritic input-output gain, enhancing spike synchrony in network models.

Mapping vestibular and visual contributions to angular head velocity tuning in the cortex

The paper maps the distribution of angular head velocity (AHV) sensitive neurons across cortical areas and identifies their dependence on vestibular and visual inputs.

Ca2+ signaling in astrocytes is sleep-wake state specific and modulates sleep

This study identifies sleep-wake specific astrocytic Ca2+ signaling and its role in modulating sleep transitions and stability.
