An introductory psychology, with some educational applications . Fig. 4. The human brain viewed from above. Tlie cerebral hemispheres completely cover the rest of the brain 42 AN mTRODUCTORY PSYCHOLOGY important part of the brain.

Thehemispheres are divided into lobes, the frontal lobes in thefront part of the skull cavity, the temporal lobes abovethe ears, the parietal lobes about the crown of the Fig. 5. Median longitudinal section of the human brain A, B, C, D, L, convolutions of the median surface of the cerel)rum ; E, F, the cerebellum, showing in the plane of section the inner White matter and the outer gray matter; H, the pons Varolii; K, the medulla and the occipital lobes at the back part where the skullbegins to curve in toward the neck. The position of thegreat fissures or deep canals of the surface of the braincan best be learned from the diagram. It will be seen thatthe fissure of Sylvius separates the temporal lobe fromthe frontal and the parietal, while the fissure of Rolando isbetween these two latter. See Fier. 7. THE NERVOUS SYSTEM 43 The cerebrum. The cerebrum is a most complex anddelicate organ. Its cortex is the great receiver of stimula-tions from the sensory tracts, the great dispatcher of currentsalong the motorcourses, while, evenmore important, itsneurones are the greatconnecting factors be-tween the sensory andthe motor larger part of thece
