Elucidating an anterior cingulate circuit for self-initiated actions and rescue of Parkinsonian akinesia

This study identifies a cortical circuit involving ACC-D1+ neurons critical for initiating goal-directed movements and shows its therapeutic potential in Parkinsonian akinesia.

A2A-positive neurons in the nucleus accumbens core regulate effort exertion

This study shows that A2A-positive neurons in the NAc core regulate effort exertion by bidirectional modulation of lever pressing behavior in an effort-dependent manner.

eLemur: A cellular-resolution 3D atlas of the mouse lemur brain

eLemur provides a 3D cellular-resolution brain atlas for the mouse lemur, enabling detailed anatomical and cellular analysis to support neuroscience research.

Real-time visualization of mRNA synthesis during memory formation in live animals

The paper uses a genetically-encoded RNA indicator to visualize Arc mRNA dynamics in live animals during memory formation and retrieval, revealing rapid turnover in hippocampal neurons and stable expression in retrosplenial cortex neurons.

Topographic connectivity and cellular profiling reveal detailed input pathways and functionally distinct cell types in the subthalamic nucleus

The paper maps connectivity and identifies functionally distinct cell types in the subthalamic nucleus using mouse and human data.

All-optical imaging and patterned stimulation with a one-photon endoscope

The paper introduces a new system for simultaneous calcium imaging and optogenetic stimulation in freely moving mice, demonstrating its ability to image and activate specific neurons and recreate behavior.
