Abstract

Generation of the activity pattern characteristic of the Br type cell (cell RPal) located in the right parietal ganglion of Helix pomatia L. was found to be temperature dependent. It displayed bursting activity only between 12 and 30° C. Below 12°C and above 30°C the burst generation disappeared and the spike distribution became continuous. With increasing temperature the duration of impulses and the interspike interval decrease. At different temperatures not only the places of maxima of the interspike interval histograms are different, but also the character of the curves describing the spike distribution changes. With increasing temperatures the duration both of the bursts and of the interburst intervals is shortened. The parameters of potential generation depend not only on the absolute value of the temperature but also on the actual value and speed of its change.
