Abstract
The genetics and neurochemistry of locomotor activity inDrosophila have received increasing attention, although no precise relationship has been formulated, and researchers have not always distinguished the various forms of activity. In the present research, using the dopamine-deficientTyr-1 mutant, we demonstrate that it is possible to operationally define and provide separate measures of spontaneous activity and reactivity and have also isolated a third, distinct, category of locomotor activity which we term “stimulated” activity. Our data indicate thatTyr-1 mutants do not differ from isogenic wild-type flies with respect to spontaneous activity or reactivity but that they do display significantly higher stimulated activity levels. It is suggested that low levels of dopamine inTyr-1 may result in increased stimulated activity rather than spontaneous activity as previous research has suggested.
