Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

Electrophysical Generation of Pulse and Plateau Potentials in Paramecium

AUTHORS: Yumi Takizawa, Atsushi Fukasawa

Download as PDF

ABSTRACT: This paper presents electrophysical potential generation in paramecium of unicellular organism. Modelling and analysis are done by equivalent electrical circuit in equations. Activity is composed of electrical three zones and two depletion layers induced in the cytoplasm. Analysis was done on space-time dynamic motion of charges (ions). Electrical equivalent circuit of activity and active cell are given. Characteristics analysis is done for amplifier and oscillator. Positive pulse and its variations as negative pulsed, positive plateaus are realised in this modelling.

KEYWORDS: Paramecium, positive and negative potential generation, positive pulse, swimming directions, Ca2+ and K+ charges (ions)
