The mu-opioid receptor and the evolution of mother-infant attachment: theoretical comment on Higham et al. (2011).

Behavioral neuroscience - 1 Apr 2011

Curley James P

Abstract excerpt

Genetic variation at a single nucleotide polymorphism (SNP) in the mu-opioid receptor gene (OPRM1) of both humans and rhesus macaques Macaca mulatta has been associated with differential affinity to the endogenous ligand beta-endorphin as well as alterations in pain sensitivity, drug and alcohol dependence, and social behaviors. The new study by Higham et al. (2011) presented in the current issue of this journal...
