Protoplasmic Streaming of a Slime Mold, Physarum Polycephalum* Ii . Theoretical Treatment 01~ the Electric Potential Rhythm by Uichiro Kishimoto

Abstract

The electric potential difference (1 to 15 Inv.) between two loci of the slime mold connected with a strand of protoplasm changes rhythmically with the same period (60 to 180 seconds) as that of back and forth protoplasmic streaming along the strand. When atmospheric pressure at a part of the plasmodium is increased (about 10 cm. H~O), the dectric potential… (More)
