Age affects the metabolic rate of insect brain.
Brains of adult insects can be isolated and studied in vitro. In female blowflies the oxygen uptake of the brain is age dependent. A steady increase is followed by a precipitous decrease around the middle of the little span. These changes are accompanied by alterations of mitochondrial structure and deposits of lipofuscin-like material.
