Rhythmic light stimulation elicits multiple concurrent neural responses that separably shape human perception

As you listen to a story, the meaning of each word you hear relates to the meaning of prior words. But how? We operationalized semantic distance, and identified brain regions that correspond to this rolling summary measure during naturalistic listening. #neuroscienceoflanguage
Check out our preprint (linked again here: osf.io/preprints/ps...) where we measured neural sensitivity to changes in semantic space while listening to a podcast. Not only do we look at word-to-word but larger chunks too (2-gram, 5-gram, 10-gram) to examine meaning construction at multiple levels.
