Horizontally Tiled Network of Cortico-Basal Ganglia Modules Performs Reinforcement Learning

This study demonstrates that reinforcement learning can be achieved through horizontal signal transmission between horizontally tiled cortico-basal ganglia modules, leveraging differences in basal ganglia pathway projection ranges.

Rhythm Receptive Fields in Striatum of Mice Executing Complex Continuous Movement Sequences

The paper investigates rhythm receptive fields in the striatum of mice performing complex movements, finding neurons sensitive to movement rhythm parameters and highlighting their role in motor coordination.

Recognition memory: familiarity signals increase selectively in the lateral entorhinal cortex following hippocampal lesions

This study shows that hippocampal lesions increase lateral entorhinal cortex activity during familiarity judgments, suggesting HIP modulates LEC in recognition memory.

Mutations in CalDAG-GEFI Lead to Striatal Signaling Deficits and Psychomotor Symptoms in Multiple Species Including Human

This study identifies CalDAG-GEFI mutations causing psychomotor symptoms and bleeding in multiple species, revealing conserved signaling deficits in striatal function.
