While the basal ganglia have long been thought to mediate learning through dopamine-dependent striatal plasticity, their regulation of motor thalamus plays an unexpected and critical role in reinforcement.
Dopamine neurons make novel glutamatergic connections to striatal cholinergic interneurons in the lateral dorsal striatum that are mediated by metabotropic glutamate receptors coupled to TrpC channels.
M2 cortex-dorsolateral striatum circuit is functionally altered in Huntington's disease and, by boosting its activity, we reverse symptoms at behavioral, physiological, and morphological level in symptomatic mice.
Optical recordings reveal previously unknown neuromodulator dynamics in the striatum during animal movements that suggest a new interpretation of the underpinnings of bradykinetic movements exhibited in Parkinson's Disease patients.
Behavioral, pharmacological, optogenetic, electrophysiological and computational analyses suggest that the anterior dorsal striatum is a causal node in the network responsible for evidence accumulation.
The first comprehensive map of all excitatory inputs to the mouse striatum is presented and used to define and demarcate striatal subdivisions, including a previous unappreciated novel subdivision in the posterior striatum.
