Astrocytes (a type of glial cell) make up the BBB 9/28/10 Parts & Functions of the Brain Cerebral Cortex most of the brain, split up into 4 areas: 1. Frontal Cortex behavior and higher functioning 2. Parietal Cortex sensory info 3. Temporal Cortex - hearing 4. Occipital Cortex - vision Cerebellum under the cerebrum responsible for 9/28/10 Parts & Functions of the Brain Hippocampus involved in LEARNING and MEMORY (short term to long term) Amygdala involved in EMOTIONAL or painful MEMORIES Thalamus RELAY FOR ALL SENSORY INFO EXCEPT OLFACTORY 9/28/10 Should be familiar with this slide 9/28/10 Example Questions: Which part of the brain is NOT involved in control of motion? A. Pons B. Primary Motor Cortex C. Cerebellum D. Thalamus E. Brocas area Which of the following areas in the cerebrum is most likely to be affected if a person can visualize and hear a word but cannot speak the word? 9/28/10 Example Questions: Destruction of which of the following would result most immediately in death of the individual? A. Medulla Oblongata B. Primary Motor Cortex C. Cerebellum D. Thalamus E. Brocas area Damage to ventral root will most likely affect: A. Descending signals in the spinal cord Ascending signals in the spinal cord 9/28/10 Lecture 2: The Neuron Chapter 5 & 8 9/28/10 Main points to know : The Neuron (Parts and Functions) Glial Cells Should know the electrical terms Know the main ions involved and Equilibrium Potentials 9/28/10 Neuron...
