Evidence for a dichotomy between the planning of an action and its on-line control in
humans is reviewed. This evidence suggests that planning and control each serve a …

Motor cortex in the primate brain was once thought to contain a simple map of the body's
muscles. Recent evidence suggests, however, that it operates at a radically more complex …

Populations of cortical neurons flexibly perform different functions; for the primary motor
cortex (M1) this means a rich repertoire of motor behaviors. We investigate the flexibility of …

The cortical population code is pervaded by activity patterns evoked by movement, but it
remains largely unknown how such signals relate to natural behavior or how they might …

We show that while a primate chooses between two reaching actions, its motor system first
represents both options and later reflects selection between them. When two potential …

The motor cortical substrate associated with reaching was studied as monkeys moved their
hands from a central position to one of eight targets spaced around a circle. Single-cell …

In the macaque monkey ventral premotor cortex (F5),“canonical neurones” are active when
the monkey observes an object and when the monkey grasps that object. In the same …

What aspects of movement are represented in the primary motor cortex (M1): relatively low-
level parameters like muscle force, or more abstract parameters like handpath? To examine …

A major hurdle to clinical translation of brain–machine interfaces (BMIs) is that current
decoders, which are trained from a small quantity of recent data, become ineffective when …

Finger-tapping tasks are one of the most common paradigms used to study the human motor
system in functional neuroimaging studies. These tasks can vary both in the presence or …
