13. neural correlates of dreams Flashcards
what was the study on the neural correlates of dreams?
- sought to identify specific brain regions and neural patterns associated with both the occurrence of dreams and their content
- The activity in the posterior cortical hot zone was particularly prominent when the dreams included vivid sensory experiences, such as seeing people or scenes.
- different types of dream content were associated with specific neural patterns
- The findings imply that the posterior cortical hot zone may play a critical role in generating conscious experiences in both wakefulness and sleep.
what is the problem with the study on the neural correlates of dreams
no one can replicate it
so do we have the neural correlates of dreaming?
no… we still can’t look at someone’s brain and tell if they are dreaming.
But there’s obviously some regularities in terms of global brain activations.
the study on dream recallers vs non recallers: what did they find
those who remember dreams have difference in brain activation.
Ability to remember dreams is linked with ability for memory encoding
Mind reading: imagination. If you’re somebody that is able to generate vivid imagery, much more likely to remember dreams.
what did hobson want to do
Hobson wanted to disprove freud. saying dreams are just biological. dreams are meaningless
what did solms think
Solms started neuropsychoanalysis. He says no contradiction between brain science and psychoanalysis. He says no no, freuds is not totally irrelevant.
what is the theory of hobson
activation synthesis hypothesis
Activation of the brain. You experience something like dreams. But Hobson says it has nothing to do with anything. We make sense of it afterwards.
what is a dream according to hobson
Epiphenomenon of REM sleep: Phenomenon that is not real. Just brain doing its thing in sleep.
neuropsychoanalysis
putting together psychoanalysis and neuroscience
what solms proposed linked with rem sleep and dreaming
rem sleep and dreaming are 2 dissociate processes
He would say: yes rem sleep seems like a really good time to be dreaming. But you can have rem sleep without dreams and dreams without rem sleep.
what part of the brain did solms say was needed for dreams?
prefrontal cortex
what is the main motivator of your dreams according to mark solms
Your affective emotional life
what is the covert rem theory of Nielsen
aims to reconcile the hobson and solms theories.
elements of REM sleep are found during other sleep stages and may be correlated with mental activity. the idea that maybe rem is not a perfectly distinct stage but rather a continuum of qualities and elements
what happened in the study where participants were sleep deprived from rem sleep specifically
they rated their dream much more dream like
