چکیده انگلیسی
Differences in the c-fos expression of CA1, CA3, BL Amygdala, LS and BNST were found between the short- or long-context groups with a pre-exposure before cued conditioning. Ce Amygdala showed no differences in the c-fos expression labeling. We reported the hippocampal c-fos activation during the cued fear conditioning acquisition. Specifically, the CA1 activation could be related with the context-US processing during the CS-US association acquisition, which might prove that the CS-US associations cannot be made without an integrated context participating. The results showed that a long-context exposure prior to cued conditioning produces an inhibition of the CR (freezing), and this phenomenon is related with a specific c-fos expression in CA1, CA3, BL Amygdala, LS and BNST during the fear acquisition.
