This study shows prefrontal astrocytes encode reward contingencies and adapt to changes in reward associations, influencing conditioned behavior.

This paper develops a head-fixed ethanol self-administration model in mice, demonstrating reliable ethanol-seeking behavior and relapse-like reinstatement of lever pressing.

This study uses two-photon calcium imaging to analyze corticostriatal neuron activity in mice during heroin self-administration and relapse, identifying distinct neuronal ensembles and their role in drug-seeking behaviors.

The paper identifies specialized neuronal ensembles in the dmPFC that encode reward-related information during conditioning, showing differential emergence and stabilization across learning.

This study shows capillary pericytes influence blood flow but with slower kinetics than upstream cells, and their removal increases blood flow.

This paper describes a new experimental assay allowing mice to self-administer drugs while head-restrained, enabling simultaneous multiphoton imaging of neural activity during drug use and relapse.

The paper identifies two transitional mural cell types in adult mouse cortex with distinct -smooth muscle actin levels and morphological features.
