Dimensionality reduction approaches on functional MRI data reveal that human reward-based motor learning emerges from dynamic changes in functional brain network interactions among sensorimotor, attention, and default mode networks.

Neurons in the midbrain superior colliculus of free-flying echolocating bats represent 3D sensory space, and the depth tuning of single neurons is modulated by an animal's active sonar inspection of physical objects in its environment.
State anxiety alters the dynamics of beta oscillations during reward-dependent motor learning, thereby impairing proper updating of motor predictions when learning in unstable environments.
