The proportion of the cortical sheet characterized by dense myelination (%Myelin). The left graph shows the %Myelin in female and male voles exposed to HC (white) or LC (black) amounts of parental care. The %Myelin in LC females was significantly lower than in HC females. The right graph shows the %Myelin in female and male voles treated with saline (gray), OT (white), or OTA (black). There were no differences between any of these groups. *, significantly different from other group within the same sex
