Thalamus orchestrates local acetylcholine-dependent dopamine release in the learning striatum
By onThalamic input can trigger dopamine release in the striatum during motor learning, likely reflecting action vigor rather than motor error. Changes in this mode of dopamine release may contribute to motor and non-motor symptoms of PD.

By onPavlovian Conditioning Protocols for Mouse Behavioral Studies Derived from Fushiki et al 2024.
Cryo-EM structure of soluble VPS13C suggests its regulation by a conformational switch and by calmodulin
By onStructural studies of the Parkinson's protein VPS13C provide a molecular basis for understanding its function and regulation.
Q-DOAS: A Proximity Quenching Assay for Real-Time Detection of Early Protein Aggregation Events
By onWe describe Q-DOAS, a plate-reader assay that quantifies protein self-assembly in real time via proximity-quenching of a single, site-specifically conjugated dye (BODIPY-TMR), and which allows quantification of pre-amyloid oligomers.
