1. Brain Structure

2. HINDBRAIN structures in the top part of the spinal cord, controls basic biological functions that keep us alive.

3. MEDULLA controls blood pressure, heart rate, and breathing

4. PONS connects the hindbrain with the mid and forebrain, also involved in the control of facial expressions

5. CEREBELLUM portion of the lower brain that coordinates and organizes bodily movements for balance and accuracy

6. MIDBRAIN between the hind and forebrain, coordinates simple movements with sensory information

7. FOREBRAIN controls what we think of as thought and reason

8. THALAMUS portion of the lower brain that functions primarily as a central relay station for incoming and outgoing messages from the body to the brain and the brain to the body

9. HYPOTHALAMUS portion of the lower brain that regulates basic needs (hunger, thirst) and emotions such as pleasure, fear, rage, and sexuality

10. AMYGDALA AND HIPPOCAMPUS two arms surrounding the thalamus, important in how we process and perceive memory and emotion

11. THE LIMBIC SYSTEM The Hypothalamus, Amygdala and Hippocampus- are grouped together and called because they all deal with aspects of emotion and memory

12. CENTRAL NERVOUS SYSTEM brain and spinal cord

13. PERIPHERAL NERVOUS SYSTEM - all other nerves

14. SOMATIC NERVOUS SYSTEM - controls voluntary movements

15. AUTONOMIC NERVOUS SYSTEM - controls involuntary movements

16. SYMPATHETIC NERVOUS SYSTEM - speeds things up prepares body for fight or flight

17. PARASYMPATHETIC NERVOUS SYSTEM - brings the body back to normal

18. CEREBRAL CORTEX - covers the lower brain controls mental processes such as thought

19. FRONTAL LOBES contains the motor strip and frontal association area

20. MOTOR STRIP band running down the side of the frontal lobe that controls all bodily movements

21. PARIETAL LOBES area that contains the sensory strip

22. OCCIPITAL LOBES area that interprets visual information

23. TEMPORAL LOBES area responsible for hearing and some speech functions

24. HORMONES chemical regulators that control bodily processes such as: emotional responses growth sexuality

25. PITUITARY GLAND the master gland of the body that activates other glands and controls the growth hormone

26. THYROID GLAND controls and regulates the speed of bodily processes called metabolism

27. ADRENAL GLANDS glands that release the hormone that causes excitement in order to prepare the body for an emergency

28. ADRENALINE chemical that prepares the body for emergency activity by increasing blood pressure, breathing rate, and energy level

29. ABSOLUTE THRESHOLDS minimum stimulation necessary to detect a stimulus 50% of the time candle flame from 30 mi watch ticking from 20 ft wing of a bee falling on check from height of ½ inch single drop of perfume in three-room apartment one teaspoon of sugar in two gallons of water

30. SIGNAL DETECTION THEORY absolute thresholds vary depending on experience, motivation, expectation, alertness (sister hearing baby cry)

31. SUBLIMINAL any signal below threshold (by definition you will detect it some % of time)

32. DIFFERENCE THRESHOLD the minimum difference that a person can detect between two stimuli

33. WEBER’S LAW to perceive a difference, two stimuli must differ by a constant minimum percentage (rather than a constant amount)
