Habituation and dishabituation of the gill-withdrawal reflex in Aplysia

WebThe gill-withdrawal reflex of Aplysia can be habituated not only by harmless stimulation of the siphon, but also sensitized by painful stimuli administered in the tail region. In the course of sensitization, the experience of an unpleasant or harmful stimulus brings the nervous system into a state of heightened sensitivity to reflexive stimuli ...

WebMar 27, 1970 · A behavioral reflex mediated by identified motor neurons in the abdominal ganglion of Aplysia undergoes two simple forms of shortterm modification. When the gill-with-drawal reflex was repeatedly evoked by a tactile stimulus to the siphon or mantle shelf, the amplitude of the response showed marked decrement (habituation). WebMar 28, 2006 · The molecular mechanisms contributing to implicit memory storage have been most extensively studied for the gill- and siphon-withdrawal reflex of Aplysia ( Kandel, 2001 ). As is true for other types of defensive reflexes, the gill- and siphon-withdrawal reflex can be modified by several different forms of implicit learning.
