TY - JOUR T1 - <em>Drosophila</em> Mutants that Are Motile but Respond Poorly to All Stimuli Tested: Mutants that have a large defect in interaction with stimuli or in executive function JF - bioRxiv DO - 10.1101/045062 SP - 045062 AU - Lar Vang AU - Julius Adler Y1 - 2016/01/01 UR - http://biorxiv.org/content/early/2016/03/21/045062.abstract N2 - Adult Drosophila melanogaster fruit flies were placed into one end of a tube near to repellents (benzaldehyde and heat) and away from the other end containing attractants (light and a favored temperature). They escaped from the repellents and went to the attractants. Motile mutants that failed to do that were isolated. They did not respond to any external attractants tested or external repellents tested. In addition, they did not respond well to internal stimuli like hunger, thirst, and sleep. Some possibilities for explaining the deficiency: They may be considered defective in decision making that results from faulty interaction with the sensing mechanism, or, alternatively, the mutants may be defective in executive function. The mutants failed at both 34°C and, in one case studied, at room temperature. ER -
