  1. dreaming brain dreams, we all experience them yet.
  2. How much do we actually understand about them?
  3. There is yet to be much more research done on
  4. dreams because they are relatively still very mysterious what dreams
  5. are not as crucial for researchers.
  6. Disease states, for example, dreams themselves are very interesting and
  7. understanding them better.
  8. Could help patients with PTSD in which they have recurring
  9. nightmares. This presentation will attempt to help you better understand
  10. what is happening in the brain when we dream and
  11. if dreams have a purpose according to better understand dreams,
  12. we have to take a look at the brain areas
  13. that are active when dreaming.
  14. Additionally, it's important to note that dreaming mainly occurs during
  15. rem sleep, although the prefrontal cortex is mainly inactive, The
  16. venture, medial prefrontal cortex and the parietal occipital temporal junction
  17. are active and dreaming and are thought to actually help
  18. produce dreams.
  19. You could see the ventral medial prefrontal cortex in blue
  20. on the picture on the left and the three look
  21. dumb junction circled in red on the right.
  22. Additionally, the limbic system, motor cortex and visual spatial regions
  23. are active.
  24. one dreaming in the limbic system specifically black and colleagues
  25. discover the important role of the basal lateral in Magdala
  26. and dreaming.
  27. They compared control patients to people with her bitch with
  28. disease. This disease causes leeches in the amygdala, which you
  29. can see in the picture on the right.
  30. The top picture is a brain of a healthy brain
  31. compared to the pictures underneath the patient allegiance to the
  32. amygdala. So patients that have damaged their Magdala had less
  33. unpleasant and emotionally negative dreams, more positive emotions shorter, simpler
  34. and less intense threats in their dreams, which you can
  35. see demonstrated in the graphs below.
  36. And this is because the Magdala plays a role in
  37. the intensity of emotions and dreams interestingly dreaming of a
  38. movement actually elicits activation in the sensory motor cortex which
  39. is labeled below in the dark blue and red.
  40. So Dressler and colleagues asked lucid dreamers to clench their
  41. fists while dreaming because lucid dreamers can relatively control their
  42. dreams and their aware that they're dreaming.
  43. This led to increased blood flow and oxygenation to the
  44. sensory murder area.
  45. However, the dreamers did not clench their fists in real
  46. life because of the brain stem inducing muscle paralysis, which
  47. actually helps you not act out your dreams in real
  48. life. So pictures see shows up from MRI scans of
  49. the dreamer clenching their fists and how I activated the
  50. sensory motor cortex in comparison to picture a in which
  51. the person clench their fist when they were awake.
  52. So what about the functions of dreams?
  53. Well, Malinowski and Horton found that earlier in the night
  54. dreams help consolidate our episodic memory and they're more focused
  55. on our recent waking memories.
  56. While later in the night dream content is more emotional
  57. and bizarre memory and emotions tied together because rem sleep
  58. consolidates emotional memories.
  59. So walker described dreaming as overnight overnight therapy because there
  60. is no your adrenaline, which is an anxiety related molecule.
  61. This helps your dreams to sort through the heavy emotions
  62. that you experience throughout the day.
  63. Dreaming also plays a role in creativity and problem solving.
  64. So in summary um dreaming, it's an emotional processing and
  65. it activates the limbic system in sensory motor area.
  66. These studies help broaden our knowledge on dreams.
  67. However future studies need to focus on how to better
  68. improve research on dream content and it's possible roles in
  69. therapy. Thank you so much for listening and hearing my
  70. sources.
