[Effect of temperature on the spontaneous rhythmic activity of the neurons in the spinal centers of the frog lymphatic hearts].
Spontaneous rhythmic bursts of impulses were recorded from motoneurons related to posterior lymphatic hearts in 10th and/or 11th ventral roots of isolated frog spinal cord in vitro at the temperature of 1 degree C to 28 degrees C. The burst frequency varied from 10-12/min (at 1-3 degrees C) to 50-70/min (at 26-28 degrees C). The mean burst frequency for the 5-15 degrees C range was 2.5 +/- 0.22. High temperature sensitivity of neurons in spinal centers for lymphatic hearts of frogs may be an efficient mechanism for temperature adaptation of these poikilothermic animals.
