Gill-withdrawal reflex
WebThe gill-withdrawal reflex circuit relies heavily on two different populations of neurons: the glutamatergic sensory neurons that receive somatosensory information from the skin of the siphon, and the motor neurons that control the muscles of the gill. By using two different tiny glass pipettes, they could impale these neurons, inducing action ...

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 … See more Nonassociative learning is a change of the behavior of an animal due to an experience from specific kinds of stimuli. In contrast to associative learning the behavioral change is not caused by the animals learning … See more A two-component reflex is triggered when a weak or moderate stimulus is applied to the siphon or the mantle shelf. These two components … See more • Bristol, A.S., Marinesco, S., & Carew, T.J. (2004). Neural Circuit of Tail-Elicited Siphon Withdrawal in Aplysia. II.

WebFurthermore, activity in identified MNs may vary in response to a uniform stimulus and is not a good predictor of gill behavior. Immunohistochemical staining in gill and siphon … WebPain in invertebrates is a contentious issue. Although there are numerous definitions of pain, almost all involve two key components.First, nociception is required. This is the ability to detect noxious stimuli which evokes a reflex response that moves the entire animal, or the affected part of its body, away from the source of the stimulus. The concept of …
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. Web0 out of 1 points Question 8 If sensitization of the gill-withdrawal reflex is heterosynaptic, which would occur? Answers: a Touching the mantle will not cause a gill-withdrawal response. b. Touching the siphon will not cause a gill-withdrawal response. c. Touching the mantle will cause a gill-withdrawal response d. Touching the tail will not ...
