Adrenocortical response to open-field test in rats with anterodorsal thalami nuclei lesion.
The influence of limbic anterodorsal thalami nuclei (ADTN) on adrenocortical activity and on emotional reactivity were investigated in male and female rats. The emotional reactivity was evaluated by means of the open-field test and the corticoadrenal function by means of plasma and adrenal corticosterone concentration. The results demonstrate that ADTN lesion does not affect the behavioural patterns in the open-field test on the 29th and 30th day after lesion nor adrenal response when animals are exposed to a novel situation.
