Dr. Anne Marie Brady
The locus coeruleus (LC) and the amygdala are two areas of the brain involved in anxiety. Benzodiazepines, such as diazepam, decrease anxiety behaviorally. Histological data using cFos also supports diazepam’s role in reducing anxiety, through possible regulation by the LC and amygdala. It was hypothesized that a dose-dependent decrease in anxiety after administration of 0, 0.5 and 1.0 mg/kg of diazepam would be seen both on the elevated plus maze and open field after repeated testing and on anxiety-induced cFos expression in both the LC and amygdala. No significant effects of dose were seen behaviorally or in the number of activated cells, suggesting either these areas do not influence anxiety or that different experiments are needed to see their effects.
