Repeatedly touching the siphon ends in habituation of the gill withdrawal reflex, and a weaker gill withdrawal. This habituation was because of a decreased release of glutamate from the siphon sensory neuron onto the gill motor neuron. Activation of the sensory neuron causes release of glutamate onto the motor neuron that controls the gill, binding to glutamatergic receptors and causing an EPSP response in the motor
Vape E-Liquid neuron. The gill-withdrawal reflex circuit depends closely on two totally different populations of neurons: the glutamatergic sensory neurons that obtain somatosensory info from the pores and skin of the siphon, and the motor neurons that control the muscles of the gill.
When a stimulus, akin to a hungry predator (or an experimenter’s paintbrush), grazed the siphon, the Aplysia would reflexively withdraw their gill, as if to guard this vital organ by shrinking away from the menace. Although there was a robust gill withdrawal reflex following the one poke, Kandel and colleagues noticed that after repeated pokes to the siphon, the gill withdrawal reflex got weaker. 1.
