00:01 - 00:05
dreaming brain dreams, we all experience them yet.
00:06 - 00:07
How much do we actually understand about them?
00:08 - 00:09
There is yet to be much more research done on
00:09 - 00:13
dreams because they are relatively still very mysterious what dreams
00:13 - 00:14
are not as crucial for researchers.
00:14 - 00:18
Disease states, for example, dreams themselves are very interesting and
00:18 - 00:19
understanding them better.
00:19 - 00:21
Could help patients with PTSD in which they have recurring
00:22 - 00:25
nightmares. This presentation will attempt to help you better understand
00:25 - 00:27
what is happening in the brain when we dream and
00:27 - 00:31
if dreams have a purpose according to better understand dreams,
00:31 - 00:33
we have to take a look at the brain areas
00:33 - 00:34
that are active when dreaming.
00:35 - 00:38
Additionally, it's important to note that dreaming mainly occurs during
00:38 - 00:42
rem sleep, although the prefrontal cortex is mainly inactive, The
00:42 - 00:45
venture, medial prefrontal cortex and the parietal occipital temporal junction
00:45 - 00:48
are active and dreaming and are thought to actually help
00:48 - 00:48
produce dreams.
00:49 - 00:51
You could see the ventral medial prefrontal cortex in blue
00:52 - 00:54
on the picture on the left and the three look
00:54 - 00:56
dumb junction circled in red on the right.
00:57 - 01:00
Additionally, the limbic system, motor cortex and visual spatial regions
01:01 - 01:01
are active.
01:01 - 01:06
one dreaming in the limbic system specifically black and colleagues
01:06 - 01:08
discover the important role of the basal lateral in Magdala
01:09 - 01:09
and dreaming.
01:10 - 01:12
They compared control patients to people with her bitch with
01:12 - 01:15
disease. This disease causes leeches in the amygdala, which you
01:15 - 01:17
can see in the picture on the right.
01:17 - 01:20
The top picture is a brain of a healthy brain
01:20 - 01:23
compared to the pictures underneath the patient allegiance to the
01:23 - 01:27
amygdala. So patients that have damaged their Magdala had less
01:27 - 01:32
unpleasant and emotionally negative dreams, more positive emotions shorter, simpler
01:32 - 01:34
and less intense threats in their dreams, which you can
01:35 - 01:36
see demonstrated in the graphs below.
01:37 - 01:39
And this is because the Magdala plays a role in
01:40 - 01:47
the intensity of emotions and dreams interestingly dreaming of a
01:47 - 01:50
movement actually elicits activation in the sensory motor cortex which
01:50 - 01:52
is labeled below in the dark blue and red.
01:55 - 01:58
So Dressler and colleagues asked lucid dreamers to clench their
01:58 - 02:01
fists while dreaming because lucid dreamers can relatively control their
02:01 - 02:02
dreams and their aware that they're dreaming.
02:03 - 02:06
This led to increased blood flow and oxygenation to the
02:06 - 02:06
sensory murder area.
02:07 - 02:09
However, the dreamers did not clench their fists in real
02:09 - 02:12
life because of the brain stem inducing muscle paralysis, which
02:13 - 02:15
actually helps you not act out your dreams in real
02:15 - 02:18
life. So pictures see shows up from MRI scans of
02:18 - 02:21
the dreamer clenching their fists and how I activated the
02:21 - 02:24
sensory motor cortex in comparison to picture a in which
02:24 - 02:26
the person clench their fist when they were awake.
02:27 - 02:29
So what about the functions of dreams?
02:29 - 02:31
Well, Malinowski and Horton found that earlier in the night
02:32 - 02:36
dreams help consolidate our episodic memory and they're more focused
02:36 - 02:37
on our recent waking memories.
02:38 - 02:40
While later in the night dream content is more emotional
02:41 - 02:44
and bizarre memory and emotions tied together because rem sleep
02:44 - 02:45
consolidates emotional memories.
02:47 - 02:50
So walker described dreaming as overnight overnight therapy because there
02:50 - 02:53
is no your adrenaline, which is an anxiety related molecule.
02:54 - 02:56
This helps your dreams to sort through the heavy emotions
02:57 - 02:58
that you experience throughout the day.
02:59 - 03:02
Dreaming also plays a role in creativity and problem solving.
03:04 - 03:08
So in summary um dreaming, it's an emotional processing and
03:08 - 03:11
it activates the limbic system in sensory motor area.
03:12 - 03:13
These studies help broaden our knowledge on dreams.
03:14 - 03:16
However future studies need to focus on how to better
03:16 - 03:19
improve research on dream content and it's possible roles in
03:19 - 03:23
therapy. Thank you so much for listening and hearing my
03:23 - 03:23
sources.
