The paper investigates the differential roles of PACAP and glutamate in parabrachial neurons in shaping pain and stress responses, showing distinct effects on injury-induced hypersensitivity and inflammation-induced pain.

The paper investigates how GalR1-expressing neurons in the vPFC and vHC differentially affect attention and impulse control, finding region-specific activity patterns linked to executive behaviors.

The paper investigates how hippocampal input to prefrontal VIP interneurons changes with activity and affects spatial working memory task learning in mice.

This study investigates the role of somatostatin neurotransmission in prefrontal cortical circuits during learning, showing it shapes configural representations and network dynamics related to salient outcomes.

This study examines how cortical neurons respond to mild TBI, identifying ATF3 as a marker for stress-responsive neurons and showing that layer V neurons die while layer II/III neurons survive.

This paper identifies distinct roles of dopamine D3 and D1 receptors in regulating motivation and reinforcement in the nucleus accumbens, showing compartmentalized signaling within the same cell type.

The paper shows that vmPFC Dyn neurons suppress defensive behaviors by releasing dynorphin in response to threats and promoting fear-related network states.

This paper investigates how the dynorphin/kappa-opioid receptor system modulates excitation-inhibition balance in prefrontal cortical circuits through pathway-specific mechanisms.

The paper characterizes striatal projection neuron heterogeneity in mice using single-nuclei multi-omics and spatial mapping, revealing distinct subtypes with unique receptor expression and disease risk contributions.

This study shows that RapGEF2 is required for cAMP-dependent ERK activation and synaptic potentiation in hippocampus, linking it to context-dependent fear conditioning and cognitive processes.

This study identifies a novel cAMP-NCS-Rapgef2-ERK-Egr-1/Zif268 pathway in D1 dopamine receptor neurons of the nucleus accumbens that is essential for cocaine-induced locomotor sensitization and conditioned place preference.
