eLife assessment
Yonk and colleagues provide a valuable and timely study showcasing the role of thalamostriatal inputs on learning and action selection. In particular, they provide solid evidence that posterior medial thalamic nucleus (POm) neurons are activated during reward expectation and arousal. A clearer conceptual assessment of the overall function of this circuit, together with sharper analyses of calcium responses and thalamic specificity, in terms of viral spread and striatal target, may further increase the impact of the study.
