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.
View. comments. Scientists think they have discovered the switch in the brain that tells our bodies when to go to sleep. The discovery, made by neurologists at Oxford University, could pave the way for a treatment to combat sleep disorders such as insomnia.cientists discover the 'switch' that tells the brain to go sleep. 1  Switch works by regulating neurons in the brain when the body is tired. 2  They demonstrated the theory on fruit flies, creating insomniac insects. 3  Scientists believe there is a similar group of neurons in the human brain.
