To begin to understand how Hoxb8 might control grooming behavior, Greer and Capecchi first analyzed where the gene was expressed in the brains of adult mice.

"Scientists can now devise experiments to learn the role...... So, we thought we might have a serious problem in demonstrating that this deletion caused epilepsy." The scientists found that due to hearing loss, these mice lose their susceptibility to seizure during maturation and, thus, would not respond to seizure-inducing sound.
