The Activation Synthesis Theory Flashcards
What stage of sleep do we dream?
REM sleep
What is the pons?
A section of the brainstem that operates as a message system.
What is the limbic system?
Part of the brain responsible for functions like memory, behaviour, and emotions.
What do the pons do while we are sleeping?
The pons send electrical signals through the brain.
What do the neurones released do in the brain?
They stimulate the cerebral cortex, which tries to make sense of the activity.
What does the theory say causes us to dream?
The effort it requires to give the brain activity meaning makes us dream.
What does the theory say makes dreams so obscure?
The firing of neurones is very random so it can be very hard to attach a meaning to them.
What are some criticisms of the Activation Synthesis Theory?
The theory is very reductionist, dreams often follow patterns which does not fit with the idea that activity is random, those with brain damage still dream even if their pons no longer produce signals.
