Inner layer of the BRAIN are of 3 types: 1)FORE-BRAIN = PROSENCEPHALON 2) MID-BRAIN = MESENCEPHALON 3) HIND-BRAIN = RHOMBENCEPHALON 1)FOREBRAIN: It is divided into 3parts a) OL-FACTORY LOBE: Function: SMELL,TASTE b) CEREBRAL HEMISPHERE/ CEREBRUM It is the largest part of the brain Function: READING, MEMORY, INTELLIGENCE, THINKING c) DIENCEPHALON/ THALAMENCEPHALON Function:** It controls the metabolic activities of the body. **It contains the nerve centres for TEMPERATURE REGULATION,HUNGER,THIRST, EMOTIONS. 2) MID-BRAIN It is divided into
