Sofosbuvir prevents memory loss in animals that survive ZIKV infection. Animals that survived from ZIKV neonatal infection, untreated or pretreated with sofosbuvir, were kept and tested for behavioural sequelae in learning and memory after 60 days. The time to find the platform, according to MWM test, was assessed. Trial in the absence of the platform was conducted (A) (*P < 0.05, Student’s t test). In panel A, latency represents the time spent exploring the quadrant where the platform was located before removal, and the data are expressed as the means ± SEM (n = 5 to 8 per experimental group). Aversive memory was evaluated by freezing behaviour 24 h post-training session, whereas mice were allowed to explore the aversive environment during 180 s followed by two foot shocks (0.6 mA, 3 s) (B). In panel B, latency represents the time spent without movement (freezing) during 180 s, and the data are expressed as the means ± SEM (n = 5 to 8 per experimental group).
