Figure 6.

The proportion of the cortical sheet occupied by the primary visual cortex (%V1). The left graph shows the %V1 in female and male voles exposed to HC (white) or LC (black) amounts of parental care. There are no differences between any of these groups. The right graph shows the %V1 in female and male voles treated with saline (gray), OT (white), or OTA (black). The %V1 of females treated with OT was significantly higher than females treated with saline or OTA, as well as males treated with OT. *, significantly different from other group within the same sex. †, significantly different from opposite sex within the same treatment group
