Are circadian clocks in antennal neurons necessary and sufficient for olfaction rhythms in Drosophila?
Antennal neurons are both necessary and sufficient for olfaction rhythms, which demonstrates for the first time that a peripheral tissue can function as an autonomous pacemaker in Drosophila. These results reveal fundamental differences in the function and organization of circadian oscillators in Drosophila and mammals and suggest that components of the olfactory signal transduction cascade could be targets of circadian regulation.
Results offer support for the idea that lack of autobiographical memory specificity mediates the known relationship between rumination and poor problem-solving.
