Previous studies have shown that intracortical activity can be used to operate prosthetic
devices such as an artificial limb. Previously used neuronal signals were either the activity of …

Significant variability in firing properties of individual neurons was observed while two
monkeys, chronically implanted with multielectrode arrays in frontal and parietal cortical …

The spiking of neuronal populations in motor cortex provides accurate information about
movement parameters. Here we show that hand movement target and velocity can be …

Large, chronically implanted arrays of microelectrodes are an increasingly common tool for
recording from primate cortex and can provide extracellular recordings from many (order of …

Previous studies have suggested that complex movements can be elicited by electrical
stimulation of the motor cortex. Most recording studies in the motor cortex, however, have …

1. Several neurophysiological studies of the primary motor and premotor cortices have
shown that the movement parameters direction, distance, and target position are correlated …

Movement representation by the motor cortex (M1) has been a theoretical interest for many
years, but in the past several years it has become a more practical question, with the advent …

The relationship between spiking activities in motor cortex and movement kinematics has
been well studied in neurologically intact nonhuman primates. We examined the …

Now that recordings of multiple, individual action potentials are being made with chronic
electrodes, it seems that previous work showing simple encoding of movement parameters …

Interactions among groups of neurons in primary motor cortex (MI) may convey information
about motor behavior. We investigated the information carried by interactions in MI of …
