T2-sequence with contrast inversion: diagnostic value in the investigation of gray matter heterotopias.

abstract：:Sex differences in event-related potentials were examined in 23 women and 24 men during a mental rotation task. We found an early (130-400 ms) and a late (400-700 ms) ERP mental rotation effect. The late rotation effect, which is thought to indicate the onset of the cognitive process of mental rotation, emerged about ...
