Oscillations in local field potentials of the primate motor cortex during voluntary movement.

Local field potential oscillations in primate cerebellar cortex during voluntary movement.

Sustained oscillations of 13-18 Hz were observed in local field potentials (LFPs) in the cerebellar cortex of a behaving monkey. These oscillations, which appeared to be generated in the granular cell layer, were particularly prominent in the paramedian lobule. The oscillatory activity decreased during drowsiness or extreme arousal and occurred most often when the animal was immobile but alert....

RAPID COMMUNICATION Local Field Potential Oscillations in Primate Cerebellar Cortex During Voluntary Movement

Pellerin, Jean-Pierre and Yves Lamarre. Local field potential joint. During training, the animal learned to perform a flexion of the elbow in response to an auditory cue (400 Hz, 35 dB, 100 oscillations in primate cerebellar cortex during voluntary movement. J. Neurophysiol. 78: 3502–3507, 1997. Sustained oscillams). The movements had to reach a preset amplitude (usually 107) within a specified...

Neural discharge and local field potential oscillations in primate motor cortex during voluntary movements.

The role of "fast," or gamma band (20-80 Hz), local field potential (LFP) oscillations in representing neuronal activity and in encoding motor behavior was examined in motor cortex of two alert monkeys. Using chronically implanted microwires, we simultaneously recorded LFPs and single or multiple unit (MU) discharge at a group of sites in the precentral gyrus during trained finger force or reac...

Local field potentials in primate motor cortex encode grasp kinetic parameters

Reach and grasp kinematics are known to be encoded in the spiking activity of neuronal ensembles and in local field potentials (LFPs) recorded from primate motor cortex during movement planning and execution. However, little is known, especially in LFPs, about the encoding of kinetic parameters, such as forces exerted on the object during the same actions. We implanted two monkeys with microele...
