EEG coherence during mental rotation of letters, hands and scenes.
The purpose of the present study was to investigate differences in the electrocortical synchronization pattern during mental rotation of three different object categories as well as six different rotation angles. Therefore, event-related coherence of the electroencephalographic (EEG) activity between selective frontal and parietal electrode pairs of ten subjects was measured during the performa...
متن کاملInhibition of motor-related activation during a simple reaction time task requiring visuomotor mental rotation.
The present study investigated whether differences in reaction time (RT) between movements initiated to a visual cue (directly cued) versus movements initiated to a location other than the visual cue (indirectly cued) arise because of varying levels of inhibition within the motor system during response preparation. Unlike typical visuomotor mental rotation (VMR) experiments, this study employed...
متن کاملHuman motor cortex activity during mental rotation.
The functional role of human premotor and primary motor cortex during mental rotation has been studied using functional MRI at 3 T. Fourteen young, male subjects performed a mental rotation task in which they had to decide whether two visually presented cubes could be identical. Exploratory Fuzzy Cluster Analysis was applied to identify brain regions with stimulus-related time courses. This rev...
متن کاملMental rotation of congenitally absent hands.
We compared motor imagery performance of normally limbed individuals with that of individuals with one or both hands missing since birth (i.e., hand amelia). To this aim, 14 unilaterally and 2 bilaterally amelic participants performed a task requiring the classification of hands depicted in different degrees of rotation as either a left or a right hand. On the same task, 24 normally limbed part...
متن کاملTask-specific strategies of mental "rotation" of facial representations.
ed, coded, and/or incomplete reflection of the object itself. Mental transformations are viewed as operations on the structure of a propositional network that lead to changes in the way the representation can be used. Investigators have attempted to devise procedures that would permit inferences as to whether analog or propositional processing is being used in mental rotation tasks, despite the...
