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.

The paper investigates how dopamine and astrocytic calcium activity coordinate during behavioral breaks in mice, showing dopamine drives astrocytic activity and affects learning.

The paper identifies striosomal pathways that target substantia nigra dopamine neurons, with opposite effects on movement compared to canonical pathways.

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.
