If there is no observed change in muscle tension, palpation is used to further assess if a contraction is present. The AIM model and Activation Synthesis Theory did not hypothesize how the neural activation of forebrain neurons actually produces dreams. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.

Wikipedia explains that information processing theory is the concept that human beings actually process information that goes into the brain. (3) The reverse reaction has an activation energy greater than 50 kJ/mol. Our brains have thousands of neural connections between memories—too many to remember them all—and that dreaming is part of "pruning" those connections. After researching and delegating we have concluded that the activation synthesis dream theory is more accurate than Freud's wish fulfilment theory. activation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport.
