Brain regions involved in dreaming:
The thalamus is a brain region that relays sensory and motor signals to the cerebral cortex and is active in creating images and information during REM sleep. The amygdala, part of the limbic system, plays a role in memory and emotional learning, and is involved in processing emotions in dreams during REM sleep.

Brain regions involved in dreaming: outcomes5 objectives
- The thalamus is a brain region that relays sensory and motor signals to the cerebral cortex and is active in creating images and information during REM sleep. The amygdala, part of the limbic system, plays a role in memory and emotional learning, and is involved in processing emotions in dreams during REM sleep.
- Hobson and McCarley's activation-synthesis theory of dreaming includes concepts such as the blockade of sensory input, blockade of motor output, random activation of neural circuits, and the synthesis of this activity in the cerebral cortex.
- Support for Hobson and McCarley's activation-synthesis theory comes from studies showing the bizarre nature of dream content, such as findings from Williams et al.
- A counterargument to Hobson and McCarley's activation-synthesis theory is that some dreams appear to have personal meaning and do not seem to be random.
- Applying the activation-synthesis theory of dreaming to new situations involves understanding how this theory can explain various dream experiences.
