Apoptosis

MB= mushroom bodies, AL= antennal lobes, OL = optic lobes, CC= central complex, SEZ= subesophageal zone RCB= remainder of the central brain. Brain region cells reflects the number of cells per brain region based on a subset of sampled brains (see methods for details). Proportion X (followed by brain region) reflects the amount of that brain region available for counting. Brain region prop indicates the proportion of apoptotic cells of each region scaled by the number of cells per region and the proportion of that region sampled. Brain region prop + 0.001 adds a constant for non-zero values. Log brain region prop are the log transformed values of brain region prop +0.001.
