Respuesta :
Despite his motor cortex being active, Paul's body does not act out the running motions because his brainstem has functionally paralyzed him due to a) REM.
REM sleep is that time of sleep when only the motor cortex of the CNS is active whereas the brainstem is resting. In this state, a person can perceive information but his body cannot act on the actions that are perceived by the brain. This is because the afferent neurons are not functioning during this time.
In the scenario mentioned in the question, Paul is scared and his motor cortex can perceive this information and give the message of running. But due to being in REM sleep, his brainstem will not allow any body movement.
