B Representative examples of GFP-labeled presynaptic boutons. Scale bars: 2.5 μm. C Quantification of presynaptic bouton density and weighted size in the mPFC (PL and IL). Mock: n= 57 axons from 6 mice; ZIKV: n= 63 axons from 7 mice. D Quantification of presynaptic bouton weighted size in the mPFC (PL and IL). Mock: n= 2974 boutons from 6 mice; ZIKV: n= 3486 boutons from 7 mice. Data information: All data were presented as mean ± SEM. *P<0.05, **P<0.01, Two-tailed unpaired t-test unless described otherwise.
