A little curiosity goes a long way.

In an fMRI study of four people, more context changed where and how semantic information was represented and improved the signal-to-noise ratio of brain responses. Models built using stimuli with little context did not generalize well to natural language.

In mice, reactivating hippocampal CA1 cells linked to social defeat reduced social interaction. Reactivating cells linked to a neutral context did not have the same effect.
