Fatherhood affects dendritic spines and vasopressin V1a receptors in the primate prefrontal cortex

Yevgenia Kozorovitskiy , Maria Hughes , Kim Lee & Elizabeth Gould

Like human fathers, male marmosets help raise their young, yet the ways in which fatherhood influences the brain remain largely unknown. We show that first-time and experienced marmoset fathers have enhanced density of dendritic spines on pyramidal neurons in prefrontal cortex as compared to non-fathers.
