The notion of internal models has become central to the study of visually guided reaching.
Armed with this theoretical framework, researchers are gleaning insights into long-standing …

When planning target-directed reaching movements, human subjects combine visual and
proprioceptive feedback to form two estimates of the arm's position: one to plan the reach …

When planning goal-directed reaches, subjects must estimate the position of the arm by
integrating visual and proprioceptive signals from the sensory periphery. These integrated …

Although multisensory integration has been well modeled at the behavioral level, the link
between these behavioral models and the underlying neural circuits is still not clear. This gap …

Most voluntary actions rely on neural circuits that map sensory cues onto appropriate motor
responses. One might expect that for everyday movements, like reaching, this mapping …

The sensory signals that drive movement planning arrive in a variety of 'reference frames',
and integrating or comparing them requires sensory transformations. We propose a model in …

Proprioception—the sense of the body's position in space—is important to natural movement
planning and execution and will likewise be necessary for successful motor prostheses and …

Recent studies have employed simple linear dynamical systems to model trial-by-trial
dynamics in various sensorimotor learning tasks. Here we explore the theoretical and practical …

Optogenetics has revolutionized neuroscience in small laboratory animals, but its effect on
animal models more closely related to humans, such as non-human primates (NHPs), has …

While optogenetics offers great potential for linking brain function and behavior in nonhuman
primates, taking full advantage of that potential will require stable access for optical …
