MEDIATOR FOR K ION CHANNEL OF APLYSIA NEURON, CONTAINING HYDROGEN PEROXIDE

摘要

PURPOSE: A K ion channel mediator of a sensory neuron of aplysia containing hydrogen peroxide is provided. A sensory neuron system of aplysia using the K ion channel mediator can be provided as a model for the study of memory and learning. CONSTITUTION: The mediator for K ion channel of a sensory neuron of aplysia contains hydrogen peroxide. In the K ion channel, a hydrogen-induced depolarization is inhibited by tetraethylammonium(TEA). The concentration of hydrogen peroxide in the range of 0.01 to 10mK induces hyperpolarization within 1hr and contributes to the increase of membrane conductance. The aplysia is an Aplysia kurodai captured in a costal area of The East Sea of Korea.
