Aplysia Gill and Siphon Withdrawal Reflex

Aplysia Gill And Siphon Withdrawal Reflex

The Aplysia gill and siphon withdrawal reflex (GSWR) is an involuntary, defensive reflex of the sea hare Aplysia californica, a large shell-less sea snail or sea slug. This reflex causes the sea hare's delicate siphon and gill to be retracted when the animal is disturbed.

Aplysia californica is used in neuroscience research for studies of the cellular basis of behavior including: habituation, dishabituation, and sensitization, because of the simplicity and relatively large size of the underlying neural circuitry.

Eric Kandel, recipient of the Nobel Prize in Physiology or Medicine in 2000 for his work with Aplysia californica, was involved in pioneering research into this reflex in the 1960s and 1970s.

Famous quotes containing the words gill, withdrawal and/or reflex:

    Culture is a sham if it is only a sort of Gothic front put on an iron building—like Tower Bridge—or a classical front put on a steel frame—like the Daily Telegraph building in Fleet Street. Culture, if it is to be a real thing and a holy thing, must be the product of what we actually do for a living—not something added, like sugar on a pill.
    —Eric Gill (1882–1940)

    A separation situation is different for adults than it is for children. When we were very young children, a physical separation was interpreted as a violation of our inalienable rights....As we grew older, the withdrawal of love, whether that meant being misunderstood, mislabeled or slighted, became the separation situation we responded to.
    Roger Gould (20th century)

    The theatre is the involuntary reflex of the ideas of the crowd.
    Sarah Bernhardt (1845–1923)
