1. THE HUMAN BRAIN

2. 3.5 pounds of gelatinous material at the root of everything we do/are

3. Characterized by sulci (sulcus) and gyri (gyrus) – sulcus—valley – gyrus—peak

4. Divided into hemispheres—right and left—via the longitudinal fissure Cerebrum and cerebellum Cerebrum divided into four lobes

6. Frontal lobe—thinking and motor movement Parietal lobe—incoming sensory information Occipital lobe—vision Temporal lobe—memory and audition

8. Right hemisphere from the left side sulci and gyri corpus callosum thalamus hypothalamus pituitary

9. medulla pons cerebellum spinal cord amygdala hippocampus

11. Another way to talk about the brain is in terms of development. ONTONGENY RECAPITULATES PHYLOGENY HINDBRAIN MIDBRAIN FOREBRAIN

12. HINDBRAIN—oldest part; buried deep in brain tissue; processes vital functions; consists of the medulla, the pons and the cerebellum MIDBRAIN—next oldest; processes visual and auditory information; consists of the thalamus and other smaller structures

13. FOREBRAIN—newest part; cortex and limbic system structures; processes thinking, feelings and motor activity; consists of the four lobes, hypothalamus, amygdala, hippocampus and others

14. THERE ARE 100 TRILLION NEURONS IN THE BRAIN WHAT IS A TRILLION?
