Updates to Study Attributes

Findings was changed:

Normal sulcation and operculisation.

OperculisationFurther covering of the insular cortex by the temporal lobe.

SulcationFirst image: the precentral and postcentral sulci (dotted arrows) are now present on either side of the central sulcus (solid arrow).Middle image: further development of the cingulate fissure (straight arrows) and collateral sulcus (curved arrow).Last image: cingulate fissure (dotted line) is in this case well seen on the sagittal series, with continuation into the marginal sulcus (curved arrow).  The parieto-occipital (straight arrow) and calcarine (dotted arrow) fissures are also well depicted on this slice.
