The effect of synthetic & natural choline on phototaxis response in Dugesia dorotocephala

Abstract

Planarians provide a unique model organism for studying the effects of cognitive enhancers like choline bitartrate. This study aims to investigate the efficacy of varying concentrations of choline bitartrate in improving conditioning and neuroplasticity in planarians. We hypothesize that higher concentrations of choline bitartrate will enhance planarian learning through faster conditioning and increased locomotion response to stimuli. However, results show that an increase in choline did not significantly enhance conditioning, supporting the null hypothesis.
