Nullizygous mice may show reduced chemically-elicited analgesia, susceptibility to seizures, increased anxiety, and altered behavioral responses to nicotine or a new environment. Homozygotes for any of several knock-in alleles exhibit altered nervous system physiology and/or sensitivity to nicotine.
