Zusammenfassung

We used event-related lateralizations of the EEG (ERLs) and reversed vision to
study visuomotor processing with conflicting proprioceptive and visual
information during pointing. Reversed vision decreased arm-related
lateralization, probably reflecting the simultaneous activity of left and right arm
specific neurons: Neurons in the hemisphere contralateral to the observed action
were probably activated by visual feedback, neurons in the hemisphere
contralateral to the response side by the somatomotor feedback. Lateralization
related to the target in parietal cortex increased, indicating that visual to motor
transformation in parietal cortex required additional time and resources with
reversed vision. A short period of adaptation to an additional lateral
displacement of the visual field increased arm-contralateral activity in parietal
cortex during the movement. This is in agreement with the Clower et al.
study (1996), which showed that adaptation to a lateral displacement of the
visual field is reflected in increased parietal involvement during pointing.
Key words: EEG, event-related lateralizations, reversed vision, pointing
