Brain activity at 70-80 Hz changes during olfactory stimulation protocols in Drosophila.

Oscillatory and synchronized activities in the mammalian brain have been correlated with the execution of complex cognitive tasks. Similar oscillations have been observed in local field potentials (LFPs) in flies, in this case correlated with different attentional states. To further test the signifi...
