  This useful study employs optogenetics, genetically-encoded dopamine and serotonin sensors, and patch-clamp electrophysiology to investigate modulations of neurotransmitter release between striatal dopamine and serotonin neurons - a topic of interest to neuroscientists studying the basal ganglia. The results suggest that the dopamine and serotonin systems operate largely in parallel, with the activation of serotonin neurons resulting in a small, transient dopamine release. The authors suggest that this interaction occurs via glutamate release in the ventral tegmental area, findings that are closely related to previous work. Some conclusions are incomplete requiring larger samples-sizes and controls.

  eLife Assessment

  This useful study uses brain stimulation and electroencephalography to study speech-gesture integration. It investigates the role of frontotemporal regions in integrating linguistic and extra-linguistic information during communication, focusing on the inferior frontal gyrus and posterior middle temporal gyrus. Reliance on activation patterns of tightly-coupled brain regions over short timescales leads to incomplete support for the study's conclusions due to conceptual and methodological limitations.

  This study identifies astrocyte-intrinsic mechanisms by which the LRRK2 G2019S, a mutation linked to familial Parkinson's disease, disrupts synaptic integrity in the anterior cingulate cortex. The findings are convincing, as they rely on a comprehensive set of in vivo and in vitro genetic, biochemical, proteomic, and electrophysiological approaches. They are important because of their translational value, being validated in both mouse models and post-mortem human samples.
