Its nodes represent well-established biological facts combined with observations of the overall behaviors of the system. The model is based on comparing and contrasting brains, computers, and neural networks. It defines a framework for understanding the relationships between the brain and the mind. It can serve both as a starting point for developing Artificial Intelligence applications for all levels of mental activities and as a guide in the search for biological correlates of observed behaviors.

However, the actual withdrawal is based on additional information. If the hand
approached the hot object from above, it will be withdrawn upward. If it
approached the object from below, the withdrawal will be downwards. Other than
the cue, the system has also considered the history of the event. This information
may have been encoded as certain motor neurons being active. The reflex
caused the activation of neurons that control antagonistic movements. In all these
cases, the action ...
