Different behavior patterns can be created by interactions of one or more pattern generators - in response to light touch, the sea slug, Tritonia, exhibits reflexive withdrawal of the body away from the stimulus (i.e. the sea slug “cringes”). However, a stronger mechanical stimulus induces the release of serotonin from specific neurons within the central nervous system and subsequent swimming behavior (i.e., an escape response). Both withdrawals of the body and swimming are driven by the same central pattern generator circuitry. This illustrates which important characteristic of central pattern generators? A. Model central pattern generators are not as complex as their real-world counterparts. B. Their rhythmic output is an emergent property of the neural network. C. Their output is not fixed but can be modified
