Thank you We sneak And here's your shmoop du jour

00:06

brought to you by rapid eye movement or r e

00:08

m not the same thing as shifty eye movement a

00:11

k something you really shouldn't do in a police lineup

00:14

Okay here's our question which had falling scientists conducted research

00:18

that led to our understanding of the effects of ram

00:20

sleep deprivations on here A potential answers for stuff comes

00:25

freud who were sure you know for his work in

00:27

psycho analysis the unconscious the ego super ego in about

00:31

a million other things with varying degrees of weird sexual

00:33

nous attached to him But he's also well known for

00:36

his work on dream analysis In short freud believed dreams

00:39

aim to keep the sleeper asleep by fulfilling all of

00:42

their wishes that would otherwise awaken them Weird yes but

00:46

we expect nothing less from freud Still he's not our

00:48

answer John allen hobson and robert mccarley meanwhile are best

00:53

known for their research on rapid eye movement sleep and

00:55

their theory explaining the cause of dreams The two essentially

00:59

argue that dreams are vaguely cohesive narratives formed by the

01:03

brain as a response to the activation of biochemical an

01:06

electrical charges that occurred during sleep called the activation synthesis

01:10

theory it directly opposes the aforementioned freudian view and instead

01:14

suggest the dreams are for the most part random thinks

01:17

this simply is the brain's effort to synthesize the random

01:19

signals triggered during rem sleep But it doesn't deal with

01:22

sleep deprivation so it doesn't fit the bill Ernest hartman

01:25

however harks back to a more freddie and understanding of

01:28

dreams A psychoanalyst himself hartman emphasized dreams as a mode

01:32

of connection making He thought that dreams carried meaning were

01:36

useful in therapy and ultimately served in drawing connections between

01:40

memories and experiences We consciously would not still nothing to

01:44

a sleep deprivation So he's not our dream answer That

01:49

leaves us with a william charles dement a sleep researcher

01:53

best known for his focus on sleep deprivation sleep disorders

01:57

sleep apnea and narcolepsy Well dement conducted research in which

02:01

he prevented participants from experiencing a full cycle of rem

02:04

sleep and then examining what happened to their sleep cycles

02:08

He found that immediately after being deprived of ram cycle

02:11

sleep the participants cycles increased from ninety minutes to one

02:14

hundred twenty minutes Funny we had a dream That was

02:17

the right answer right before ah mellower Yellow word dream 00:02:21.51 --> [endTime] interrupted
