Changes in spatial generalization during human motor adaptation
This project seeks to use novel methods to quantify incremental changes in generalization across directions during human motor adaptation. Subjects adapt to haptic force field perturbations of varying spatial complexity while receiving both visual and proprioceptive feedback.

Learning to reach with reward-based feedback
In this study, we compare the effect of reward feedback & sensory feedback on trial-by-trial adaptation in subjects as they learn to reach in new environments. The available feedback conditions are combinations of reward, visual, & proprioceptive signals.

Adaptation to visuomotor perturbations
This project is studying the human ability to adapt to visuomotor perturbations in simple and complex environments. Previous work has also included a study of the effect of error relevance on adaptation to visuomotor rotation and gain.

Electrocorticography patterns of motor adaptation in a non-human primate
(in collaboration with Dr. Moran's lab)
We trained a monkey to perform motor tasks while subject to a perturbing viscous force, as in previous human studies. By simultaneously recording local field potential activity from its cortex and comparing them to the kinematic data, we hope to identify patterns in neural activity that correspond to the process of motor adaptation.
