Specificity of the selective sensitivity of electrosensitive neuron membranes to low-frequency sinusoidal stimulation

Specificity of the selective sensitivity of electrosensitive neuron membranes to low-frequency sinusoidal stimulation

A difference in sensitivity of mollusk's neuron to intracellular injection of sinusoidal current (1-10 Hz; 5.10(-10)--5.10(-9) A) was found as well as the complete cessation of activity at certain frequency--amplitude characteristics of the current ("windows" of blocked activity) and an increasing activity at other frequency--amplitude parameters of the current ("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 key importance lies in the dependence of the hyperpolarization of the neuron upon the amplitude and the frequency of the sinusoidal irritant.

Informed consent has traditionally focused on treatment-related issues. However, since the mid-1990s, courts have debated whether informed consent should be stretched to accommodate other concerns. For example, some courts have considered whether...
