Neck proprioception and spatial orientation in cervical dystonia.
Neck muscle vibration is known to influence body orientation and posture during locomotion and stance in normal subjects. To verify the hypothesis that neck proprioceptive input can be misinterpreted in patients with cervical dystonia (CD), lateral continuous vibration was applied to the sternocleidomastoid muscle during both stepping-in-place and quiet stance, with eyes closed. The orienting r...
متن کاملNeck Proprioception Shapes Body Orientation and Perception of Motion
This review article deals with some effects of neck muscle proprioception on human balance, gait trajectory, subjective straight-ahead (SSA), and self-motion perception. These effects are easily observed during neck muscle vibration, a strong stimulus for the spindle primary afferent fibers. We first remind the early findings on human balance, gait trajectory, SSA, induced by limb, and neck mus...
متن کاملOptokinetic stimulation influences the disturbed perception of body orientation in spatial neglect.
The effect of optokinetic stimulation on the disturbed perception of body orientation in three patients with right brain damage and spatial neglect was examined. The patients were asked to direct a laser point to the position which they felt lay exactly "straight ahead" of their bodies' orientation. Without stimulation they localised the body's sagittal midplane markedly to the right of the obj...
متن کاملComplex interactions between spatial, orientation, and motion cues for biological motion perception across visual space.
Human observers are adept at perceiving complex actions in point-light biological motion displays that represent the human form with a sparse array of moving points. However, the neural computations supporting action perception remain unclear, particularly with regards to central versus peripheral vision. We created novel action stimuli comprised of Gabor patches to examine the contributions of...
متن کاملPerception of Auditory Motion Affects Language Processing
Previous reports have demonstrated that the comprehension of sentences describing motion in a particular direction (toward, away, up, or down) is affected by concurrently viewing a stimulus that depicts motion in the same or opposite direction. We report 3 experiments that extend our understanding of the relation between perception and language processing in 2 ways. First, whereas most previous...
