DOI: 10.1007/s00221-017-5088-z

Abstract: We previously examined adaptive changes of eye–hand coordination during learning of a visuomotor rotation. Gazes during reaching movements were initially directed to a feedback cursor in early practice, but were gradually shifted toward the target… read more here.

DOI: 10.1016/j.neuron.2017.09.051

Abstract: Dopamine neurons in the SNc play a pivotal role in modulating motor behavior via striatum. Here, we show that the same dopamine neuron that targets striatum also sends a direct branch to the optic tectum (superior colliculus).… read more here.

DOI: 10.1038/s41598-018-31174-2

Abstract: Humans can adapt their motor commands in response to alterations in the movement environment. This is achieved by tuning different motor primitives, generating adaptations that can be generalized also to relevant untrained scenarios. A theory… read more here.

DOI: 10.1038/s41598-021-84767-9

Abstract: Proprioceptive training is a neurorehabilitation approach known to improve proprioceptive acuity and motor performance of a joint/limb system. Here, we examined if such learning transfers to the contralateral joints. Using a robotic exoskeleton, 15 healthy,… read more here.
