9. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Our Genetic Inheritance: Genes & DNA The nucleus of every cell contains genes, which carry the code for hereditary transmission. These genes are arranged along chromosomes (strands of paired DNA).

10. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Our Genetic Inheritance: Genes & DNA Tongue-curling is one of the few traits that depends on a specific dominant gene.

12. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Our Genetic Inheritance  Evolutionary Psychology: studies how natural selection and adaptation help explain behavior and mental processes

13. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Our Genetic Inheritance: Gene-Environment Interaction Environmental factors interact with genetic factors to influence many traits. For example, early malnourishment may affect height and cognitive abilities

14. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Pause and Reflect: Why Study Psychology? Understanding neurogenesis, neuroplasticity, and stem cells helps make us better informed consumers of scientific research and more knowledgeable participants in political debates. Can you explain why?

15. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Neural Bases of Behavior Our nervous system consists of neurons (nerve cells that receive and conduct electrical impulses from the brain).

16. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Neural Bases of Behavior: The Structure of a Neuron

17. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Neural Bases of Behavior: Neural Communication Step 1: Resting polarized membrane has more positively charged ions outside of axon, yielding net negative charge inside.

18. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Neural Bases of Behavior: Neural Communication (Continued) Step 2: Depolarization occurs when voltage-controlled channels open following sufficient stimulation from surrounding neurons, allowing sodium ions in.

19. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Neural Bases of Behavior: Neural Communication (Continued) Step 3: Resting potential is restored as sodium ions flow to neighboring area and potassium ions flow out.

20. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Neural Bases of Behavior: Neural Communication (Continued) Summary: Sequential process of depolarization, followed by repolarization, continuously moves the action potential down the axon.

21. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Neural Bases of Behavior: Neural Communication (Continued) Between neurons, communication occurs through transmission of neural information across a synapse by neurotransmitters (chemicals released by neurons that alter activity in other neurons).

22. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Receiving neurons receive multiple messages from other neurons. These multiple messages then determine if an action potential occurs or not. Neural Bases of Behavior: Neural Communication (Continued)

23. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Neural Bases of Behavior: Neural Communication (Continued) Note how the axon terminals of sending neurons almost completely cover the cell body of the receiving neuron.

24. ©John Wiley & Sons, Inc. 2008 Carpenter/Huffman: Visualizing Psychology Neural Bases of Behavior: Applying Psychology to Everyday Life Key neurotransmitters: Serotonin Acetylcholine (ACh) Dopamine (DA) Norepinephrine (NE) Epinephrine (adrenaline) GABA (gamma aminobutyric acid) Endorphins
