Distinct dynamics and intrinsic properties in ventral tegmental area populations mediate reward association and motivation

The paper identifies distinct functional roles of VTA dopamine subpopulations in reward association and motivation using electrophysiology and optogenetics in mice.

Temporal scaling of dopamine neuron firing and dopamine release by distinct ion channels shape behavior

This study shows that Kv4.3 and BKCa1.1 ion channels regulate dopamine neuron firing and release on different time scales, influencing distinct phases of reinforced behavior in mice.

A midbrain dynorphin circuit promotes threat generalization

The paper identifies KOR/Dyn signaling in the midbrain as promoting threat generalization, showing an inverted U relationship between threat intensity and discrimination.
