[Temperature dependence of the electrical activity of wasp cardiac function].

Changes in the temporal structure and amplitude of electrical fluctuations connected with the heart function were revealed by the electrophysiological method. In the range of optimum temperatures, high- and low-amplitude impulses are predominantly generated. Their amplitudes differ approximately by a factor of three. Hypo- and hyperthermia stimulate pauses in heart function. Their duration increases with the unfavorable effect of temperature. During the activation of heart function, high-amplitude fluctuations are predominantly generated. In cold torpor, all forms of electric activity stop, whereas in the active state they are resumed.
