The foramen ovale is used as the entry point into the skull when conducting a Percutaneous Rhizotomy using either radio-frequency ablation, balloon compression or glycerol injection. These are performed to treat trigeminal neuralgia. In the procedure, the electrode is introduced through the cheek of an anesthetized patient and radiologically ...

Since the skull ossifies over the brain during infant development, external craniological means could be used to diagnose the internal states of the mental characters Through careful observation and extensive experimentation, Gall believed he had established a relationship between aspects of character, called faculties , with precise organs in ...
[264] [265] As brain size increased, this altered the size and shape of the skull, [266] from about 600 cm 3 in Homo habilis to an average of about 1520 cm 3 in Homo neanderthalensis. [267] Differences in DNA, gene expression, and gene–environment interactions help explain the differences between the function of the human brain and other ...
With the skull as the holotype specimen, they were grouped into a new genus and species as Sahelanthropus tchadensis, the genus name referring to the Sahel, and the species name to Chad. These, along with Australopithecus bahrelghazali , were the first discoveries of any fossil African great ape (outside the genus Homo ) made beyond eastern and ...
The skull roof is thickened. There are also very large fenestrae (window-like openings) in the skull, which are found in many dinosaurs and reduce skull weight. One of these is a large triangular antorbital fenestra in the side of the snout. The eye socket behind it is rather high.
The brain, estimated to be over 5,000 years old, was found in the skull of a 12 to 14-year-old girl. Although the brains were shriveled, they were well preserved due to the climate found inside the cave. [131] Early philosophers were divided as to whether the seat of the soul lies in the brain or heart.
The skull is much narrower than long, [7] reaching its greatest width just behind the eyes (the postorbital bar). [8] The anterior portion is "bluntly triangular". [8] In lateral view, the skull reaches its highest point at the rear of the skull table. [9] "The external nostrils overlie the internal nares". [8]
