Human functional anatomy of visually guided finger movements.
The functional anatomy of visually guided movement was investigated in 18 normal subjects performing visuomotor tracking tasks during positron emission tomography imaging. Tracking a moving target with the index finger defined a network of focal responses of relative cerebral blood flow (relCBF) located in the primary motor cortex, dorsal parietal cortex, precuneate cortex, supplementary motor ...
متن کاملSensory Population Decoding for Visually Guided Movements
We have used a new approach to study the neural decoding function that converts the population response in extrastriate area MT into estimates of target motion to drive smooth pursuit eye movement. Experiments reveal significant trial-by-trial correlations between the responses of MT neurons and the initiation of pursuit. The preponderance of significant correlations and the relatively low redu...
متن کاملDelay-induced transitions in visually guided movements.
We investigated phase dynamics of sinusoidal forearm tracking with delayed visual feedback. To this end we introduced two data analysis tools which enabled us to find several delay-induced transitions between qualitatively different regimes. Our results show that the investigation of delay-induced transitions of the phase dynamics in tracking movements provides us with insights into the underly...
متن کاملKinematics of Visually-Guided Eye Movements
One of the hallmarks of an eye movement that follows Listing's law is the half-angle rule that says that the angular velocity of the eye tilts by half the angle of eccentricity of the line of sight relative to primary eye position. Since all visually-guided eye movements in the regime of far viewing follow Listing's law (with the head still and upright), the question about its origin is of cons...
متن کاملBrain activation during smooth-pursuit eye movements.
A potential application of studying eye movements with functional MRI (fMRI) is to examine patient populations with known eye movement dysfunction, but the reliability with which normal subjects demonstrate activity in specific brain regions has not been established. To date, fMRI studies of smooth-pursuit eye movements have used relatively small numbers of subjects and have been restricted to ...
