“The MRI analyses have particularly allowed us to fine tune our understanding of the hormonal and social mechanisms that control these variations in volume of the nerve structures”, Jacques Balthazart explains. “The possibility of obtaining successive images of the brain of the same subject before and after an experimental manipulation is indeed a major advantage. Moreover, it allows us to greatly reduce the number of experimental animals that have to be sacrificed.”
