The image below is the same as the image above, except that two arrows that have been added: a yellow arrow and a purple arrow. Some mice were killed at the time indicated by the yellow arrow (after 1.5 days in their home cage), and some mice were killed at the time indicated by the purple arrow (immediately after receiving foot shocks in Context B). The brains of the sacrificed mice were then stained with an antibody that recognizes cFos. Would you expect to see more cFos expression in the hippocampi of mice sacrificed at the time indicated by the yellow arrow or at the time indicated by the purple arrow.
