  1. Brains of littermates of the indicated ages and genotypes were fixed in 4%PFA and weighed. The weights of duplicate brains of the same age and genotype were averaged when possible. Wet weights showed an 11–24% increase at the indicated ages. No standard deviation was determined because the values are derived from a ratio but an increase was consistent in all brains analyzed.
