A. A lot of wrinkles seems to have more to do with what makes humans smarter than lower animals than with what might have made Einstein smarter than you. In normal human brains, large grooves, called fissures; small ones, called sulci, and outward folds, called gyri, follow a standard plan from person to person.uman intelligence appears to be related to the branching of brain cells and the formation of complex links between them, not the shape of the platform where the links take place. Only in a rare disease called lissencephaly (''smooth brain'') is a lack of complex brain folding linked to mental deficiency.
MRI scan showing the characteristic smooth brain of an individual with lissencephaly. Lissencephaly is a set of rare brain disorders where the whole or parts of the surface of the brain appear smooth. The word lissencephaly is derived from the Greek Î»Î¹ÏÏÏÏ lissos meaning smooth and encephalos meaning brain. It is caused by defective neuronal migration during the 12th to 24th weeks of gestation resulting in a lack of development of brain folds (gyri) and grooves (sulci). It is a form of cephalic disorder.
