Depression of substantia nigra dopamine transmission is driven by retrograde neurotensin release and is enhanced by methamphetamine self-administration

Christopher W. Tschumi, Ramaswamy Sharma, William B. Lynch, Amanda Lea Sharpe, Michael J. Beckstead

The paper shows that neurotensin release from dopamine neurons drives long-term depression of D2R synaptic currents, which is enhanced by methamphetamine self-administration.

Ventral tegmental area astrocytes orchestrate avoidance and approach behavior

J. A. Gomez, Jessica Perkins, Gerard M. J. Beaudoin, N. B. Cook, Salma Quraishi, Erin A Szoeke, Thangamani Kannan, Christopher W. Tschumi, Matthew J. Wanat, Asif Mirza Maroof, Michael J. Beckstead, Paul A. Rosenberg, Carlos A. Paladini

This study shows that VTA astrocytes regulate avoidance behavior by modulating local GABA neuron activity, which inhibits dopamine neurons and blocks reward preference.
