  1. Agenda – January 17, 2012 • Quiz #2 on Nervous System • “Drugs, Inc” Video Clips • Notes: Structure and Function of the Brain

  2. Adult Human Brain • Largest and most complex mass of nervous tissue in the human body • Weighs approximately • Divided into 4 major regions:

  3. Cerebral Cortex Cerebral Cortex Features of the Cerebrum • Cortex – • Gray matter is made up of • Responsible for muscle control, sensory perception, thought, etc. • The • White matter is composed of • White matter functions to http://www.bioon.com/book/biology/whole/image/1/1-6.tif.jpg

  4. Features of the Cerebrum • The cerebrum is divided into 4 main lobes • Longitudinal Fissure – • Transverse Fissure – • Sylvian/Lateral Fissure – • Central Sulcus –

  7. Frontal Lobe • The Frontal Lobe of the brain is located deep to the Frontal Bone (forehead) of the skull. • It plays an integral role in the following functions: (Investigation: Phineas Gage) Investigation (Phineas Gage) Modified from: http://www.bioon.com/book/biology/whole/image/1/1-8.tif.jpg

  8. Specialized Regions of the Frontal Lobe • Primary Motor Cortex (PrecentralGyrus) – • Broca’s Area – • Broca’s Aphasia – • Olfactory Bulbs–

  10. Parietal Lobe • The Parietal Lobe of the brain is located deep to the Parietal Bone of the skull. • It plays an integral role in the following functions: Modified from: http://www.bioon.com/book/biology/whole/image/1/1-8.tif.jpg

  11. Specialized Regions of the Parietal Lobe • PostcentralGyrus / Primary Sensory Area – • Somatosensory Association Cortex – • Primary Gustatory Cortex –

  12. Occipital Lobe • The Occipital Lobe of the brain is located at the anterior of the cerebrum. • Its primary function is the Modified from: http://www.bioon.com/book/biology/whole/image/1/1-8.tif.jpg

  13. Temporal Lobes • The Temporal Lobes are located at the sides of the cerebrum. • They function in the following: • Specialized area of the temporal lobe: Wernicke's area • Associated with the • Located in • Wernicke’s aphasia - Modified from: http://www.bioon.com/book/biology/whole/image/1/1-8.tif.jpg
