What is the neural basis of attractive #SerialDependence? This study shows that a previous decision is reactivated during both sensory encoding and #DecisionMaking, creating a 2-stage “repulsive-followed-by-attractive” past-present interaction process @plosbiology.org 🧪 plos.io/42JCYmq
Schematic of the two-stage operational mechanism for serial dependence. The past-trial goal-based report (upper panel), stored in distinct mnemonic formats in the sensory (purple box) and prefrontal cortex (green box) (middle panel), is reactivated during present-trial information processing (lower panel). The past–present interactions occur in two stages: early repulsion and late attraction.

The cerebellum is known to control limb movements; does it also control the tongue? @rezashadmehr.bsky.social &co reveal how the #cerebellum controls the #tongue in marmosets, highlighting the role of #PurkinjeCells in terminating tongue movement at the target @plosbiology.org 🧪 plos.io/4lCK9Wj
Marmosets produced dexterous tongue movements during recordings from the cerebellar vermis. Left: Subjects made saccades to visual targets and received a small amount of food as reward via one of two tubes placed obliquely to the mouth. In the task-relevant licks, they directed their tongue to the edge of the tube to harvest food near the tip (trajectories 2, 4), or inside the tube to harvest food that was deeper (trajectories 1, 5). In task irrelevant licks, they groomed their face (trajectory 3). Top right: Subjects chose to work for consecutive trials, making saccades and allowing the food to accumulate, then harvested their cache in bouts of licking. Bottom right: The authors employed silicon probes to record from lobule VI and VII of the vermis.
