摘要
The accuracy of somatosensory saccades defined by proprioceptive cues with and without an additional tactile stimulus was investigated over a wide range of stimulus amplitudes in 16 normal subjects. The present results confirm that somatosensory saccades are less accurate and more variable than visual saccades. Accuracy was minimal for saccades directed to hand distances of 40-50 deg and increased for larger stimulus amplitudes. The additional application of a tactile cue on the fingertip was not found to influence the accuracy of somatosensory saccades significantly. (C) 2001 Elsevier Science Ltd. All rights reserved.
