Select properties of supramammillary input to adult-born dentate gyrus neurons

This study identifies a distinct subpopulation of supramammillary nucleus neurons that provide inhibitory modulation to adult-born dentate gyrus neurons, enhancing pattern separation.

Activity-induced weakening of hippocampal input to prefrontal VIP interneurons reshapes inhibitory microcircuit function: implications for spatial working memory task acquisition

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

Sub-second striatal dopamine dynamics assessed by simultaneous fast-scan cyclic voltammetry and fluorescence biosensor

The paper evaluates dLight photometry for measuring dopamine dynamics in the dorsolateral striatum, showing it can detect dopamine increases and transient kinetics during cocaine exposure and conditioning.

Ventral Tegmental Area GABA, glutamate, and glutamate-GABA neurons are heterogenous in their electrophysiological and pharmacological properties

The paper identifies electrophysiological and pharmacological differences among VTA glutamate, glutamate-GABA, and GABA neurons using a double transgenic mouse model.

A diencephalic circuit for opioid analgesia but not positive reinforcement

The paper identifies a diencephalic circuit involving the lateral habenula and lateral preoptic area that mediates opioid analgesia without reinforcement.

An amygdalo-parabrachial pathway regulates pain perception and chronic pain

The paper identifies a CeA-LPB pathway that regulates pain perception and shows its suppression in chronic pain.
