title: "Decision"-making in bacteria: chemotactic response of Escherichia coli to conflicting stimuli.
abstract: Motile bacteria presented simultaneously with both attractant and repellent respond to whichever one is present in the more effective concentration. Apparently bacteria have a processing mechanism that compares opposing signals from the chemoreceptors for positive and negative taxis, sums these signals up, and then communicates the sum to the flagella.
