To understand the relationship between memory storage sites in the brain and learned changes in behavior, the learned behavior must be characterized. However, even simple types of learning may be quite complex. Repeated elicitation of the Tritonia swim produced multiple changes in the response. Several types of acquisition curves were observed in a single experiment depending on the response component measured. Habituation (response decrement) and iterative enhancement (response facilitation) occurred simultaneously in different swim components. The acquisition curve for one component could be modulated by stimulus strength. Because the Tritonia swim neural network is well studied, it may be possible to causally relate experience-dependent behavioral changes to the underlying memory trace in this marine mollusk.
