Specifics of selective sensitivity of the neuronal electro sensitive membrane to low frequency sinusoidal stimulation


, : Specifics of selective sensitivity of the neuronal electro sensitive membrane to low frequency sinusoidal stimulation. Fiziologicheskii Zhurnal SSSR Imeni I M Sechenova 69(3): 335-342

A difference in sensitivity of the mollusk [Lymnaea stagnalis] neuron to intracellular injection of sinusoidal current (1-10 Hz; 5 .times. 10-10-5 .cntdot. 10-9 A) was found. Activity completely ceased at certain frequency-amplitude characteristics of the current (windows of blocked activity) and increased at other frequency-amplitude parameters (windows of growing activity). This may be due to some properties of the neuron's electrosensitive membrane: the specifics of the voltage-current characteristics, membrane capacity as well as the property known as force-duration relationship. The importance lies in the dependence of the hyperpolarization of the neuron upon the amplitude and the frequency of the sinusoidal irritant.
