Stimulus generalization to different levels of illumination in Paramecium caudatum" (2008). Theses and Dissertations. Paper 1190. This study was conducted to determine if paramecia (P. caudatum), unicellular organisms, could exhibit stimulus generalization as do mammals and other multicellular organisms. Paramecia were placed in a trough that was divided into two equal portions, one light and o...

Introduction: Response to morphine and role of Nitric Oxide (NO) on expression of morphine response has been studied in vertebrates. But, little evidence is provided in the matter in earlier invertebrates. This investigation for the first time evaluated the effect of NO on expression of morphine potency in Paramecium caudatum. Methods: Animal after isolation from natural media and specific i...

ARAMECIUM bursaria is one of the most widely distributed of P the species of Paramecium, though it does not as a rule occur in such large numbers in a given region as does sometimes Paramecium caudatum. It occurs commonly amid growing vegetation in the quiet parts of pools, ponds or streams. It does not flourish in regions in which the water is foul or there is much decaying vegetation. ’ The s...

The clone of the ciliated protozoan Paramecium caudatum has the immaturity period of about 60 fissions and the lifespan of about 600 fissions. These life cycle figures have been depicted through laboratory experiments that allow continuous cell divisions for hundreds, which never occur in nature. We here constructed the nature-mimicking model culture that alternated the log- and stationary phas...

Our goal is to control microorganisms as microscale smart robots for various applications. In this paper, we introduce two approaches: a novel visual feedback control system for Paramecium cells and a dynamics model of Paramecium galvanotaxis (intrinsic reaction to electrical stimulus) for procise actuation. In the former part, we propose a microrobotic control system of cells using high-speed ...

Understanding and quantifying the temperature dependence of population parameters, such as intrinsic growth rate and carrying capacity, is critical for predicting the ecological responses to environmental change. Many studies provide empirical estimates of such temperature dependencies, but a thorough investigation of the methods used to infer them has not been performed yet. We created artific...
