Spatial and temporal cellular memory traces regulate behavior. A diagram illustrating how odor information flowing through the olfactory circuit can be regulated by distinct brain regions to create a conditioned behavioral response. Behavior is posited to be regulated by multiple regions of the brain, with different regions participating during various time windows. AL, antennal lobe; LH, lateral horn; MB, mushroom bodies; DPM, dorsal paired medial; ??, unknown downstream integrator/effector neurons. The light-gray rectangle indicates the period of activity of the PN memory trace, the medium-gray rectangle the period of activity of the DPM neuron memory trace, and the black rectangle the period of the MB memory trace. Presumably, other memory traces not yet discovered participate during period not covered by these three memory traces.
