• Sleep deprivation (SD) reduces novel object/location recognition memory scores.
• SD also decreases the expression of synaptophysin, synapsin I and PSD-95 protein.
• Caffeine and modafinil improve novel object recognition memory during SD.
• Caffeine/modafinil ameliorate the reduced synaptic protein expression during SD.
We aimed to evaluate the effect of caffeine/modafinil on sleep deprivation (SD) induced alterations in recognition memory and synaptic proteins. The data revealed a beneficial effect of caffeine/modafinil against deficit in the familiar object retrieval performance and object exploration ratio after 48 h SD. Caffeine treatment prevented the SD induced down-regulation of synaptophysin and synapsin I proteins with no change in PSD-95 protein in hippocampus. However, modafinil administration improved the down-regulation of synaptophysin, synapsin I and PSD-95 proteins in hippocampus. Hence, caffeine/modafinil can serve as counter measures in amelioration of SD induced consequences at behavioural and protein levels.
