Impact of Chronic Oral Administration of Silver Nanoparticles on Cognitive Abilities of Mice

To assess the effect of silver nanoparticles on mice cognitive abilities, daily, up to 4-month period, experimental were administrated with solution. Accumulation in brain was assessed by neutron activation analysis. Cognitive abilities before and after administration evaluated Morris water maze behavioral test. No significant differences amounts accumulated found between capable incapable animals. Silver accumulation animals 4-months experiment higher than 2-months for both groups. In main test at control points 2 4 months no statistically parameters treks
