Asymmetry of the human brain.

The inner and the outer structures of symmetrical and asymmetrical brains were studied by dissection and special preparation performed on 400 brains extracted from skulls whose types had been previously determined. The brain structures are retracted at the side of the occipitopetalia, while they are in a rather lateral and anteroposition at the side of the temporoparietopetalia and the frontopetalia. The appearance of the skull and of the brain structures was studied at various levels on heads of living humans by means of computerised axial tomography.
