behavior/neurological
• in contextual fear-conditioning test, mice show less freezing behavior in the 30 min and 24 hours after training
• mice treated with clonazepam show rescue of impaired context-dependent fear conditioning
• in the elevated-plus maze, mice enter the open arms less frequently and spend less time in the open arms
• mice spend less time in the center of the open field
• mice travel more in the open field
• mice exhibit increased circling behavior
• in the open field social interaction test, mice spend less time interacting with the caged stranger mouse
• in the three-chamber social preference test, mice show no preference for the stranger mouse over an inanimate object
• mice treated with clonazepam, a positive allosteric modulator of the GABA-A receptor, show rescue of impaired social behaviors in the open arena and three-chamber test and this effect is reversed after 1 week clearing period

nervous system
• frequency of spontaneous EPSCs in hippocampal CA1 and prefrontal cortex slices is increased
• treatment with clonazepam leads to a decrease in frequency of spontaneous EPSCs, without change in amplitude
• frequency of spontaneous IPSCs in hippocampal CA1 and prefrontal cortex slices is reduced
• treatment with clonazepam increases spontaneous IPSC amplitude in the hippocampal CA1 region, but not frequency
