9. Electroencephalogram Records Temporal Activity of the Brain

10. Recording Event-Related Potentials from Infants 19-month-old7-month-old

11. Structural Damage shown w/MRI Functional Damage shown w/PET Diseased Brains - Brain Tumor

12. MRI Showing Fatal Stroke Spread of Blood

13. Wernikie’s AphasiaBroca’s Aphasia

14. Organizing Principles in the Brain

15. Front of the BrainBack of the Brain

16. Organizing Principles in the Brain 1. Different areas have different functions. 2. Despite the specialization, no brain area performs only one function. 3. The brain represents the world in maps. 4. All incoming sensory information goes through a switchboard first.

17. Most Recently Evolved Part of Human Brain - Cerebral Cortex Gyri Sulcus

18. Different areas have different functions.

19. Lateral Surface of the Brain

20. Occipital Lobe Functions:

21. Occipital Lobe Dysfunctions:

22. Temporal Lobe Functions:

23. Temporal Lobe Dysfunctions:

24. Medial Temporal Lobe Hippocampus and Memory Hippocampus Temporal Lobe Frontal Lobe

25. ACh Pathways involved in Alzheimer’s Disease Memory Structure Also find general atrophy of cortical tissue

26. Ventral Temporal Lobe Object Identification Fusiform Gyrus Prosopagnosia - Visual Agnosia - (“A convoluted red form with a linear green attachment.”)

27. Parietal Lobe Functions:

28. Parietal Lobe Dysfunctions:

29. Parietal Lesions – Contralateral Neglect Series of self-portraits by German artist Anton Raderscheidt over 8-months period of time

30. Frontal Cortex Functions:

31. Frontal Cortex Dysfunctions:

32. OrbitoFrontal Cortex Functions:

33. OrbitoFrontal Cortex Dysfunctions:

34. OrbitoFrontal Cortex The Story of Phineas Gage

35. OrbitoFrontal Cortex: Drugs and Reward Non-user Cocaine Addict No DoseCocaine Dose

36. Motor Strip - Sends Outgoing Motor Commands

37. Somatosensory Strip – Receives Incoming Sensory Info

38. These Areas are Organized with Maps

39. The Brain Represents the World in Maps. Motor Homunculus Somatosensory Homunculus

40. Artist’s Rendering of the Homunculus

41. Medial Cut through Human Brain There’s More than Meets the Eye!

42. Corpus Callosum – Connects two Hemispheres

43. The Limbic System: Managing Emotions Cingulate Cortex Amygdala Hippocampus

44. Evolutionarily Older Parts of the Brain Controlling Homeostasis Hindbrain Midbrain Pons Medulla

45. Sensory Relay Station – the Thalamus Thalamus

46. Managing Motivations/Drives – the Hypothalamus Hypothalamus

47. Ventricles of the Human Brain – Contain Cerebral Spinal Fluid (CSF)

49. Hydroencepahlus – Swelling of the Ventricles

50. Anatomy of a Neuron Incoming Message Outgoing Message

51. Action Potential of a Neuron – Sending the Message via Electrical- Chemical Signals

52. Synapses – Communication between Neurons
