Professor and cognitive neuroscientist. Functional neuroimaging of concept representation and language-based communication.
Using an encoding model based on 65 experiential features to describe each individual concept, we found that, in both sets of regions, the model could decode both kinds of concepts, even when it was trained with concepts in one category and tested with concepts in the other.

Studies of individuals with brain injury and functional neuroimaging experiments appeared to indicate that concepts for events ("wedding", "storm") and for concrete objects ("spoon", "horse") were partially represented in mutually exclusive brain regions. #neuroscience

We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires.

Two side-by-side brain activation maps. Predicted versus observed activation maps for the contrast between event words and object words.
Different kinds of concepts—from concrete objects to social events—can be decoded from brain activity based on the same interpretable code:

Really enjoyed my weekend read on 𝐚𝐜𝐭𝐢𝐯𝐞 𝐟𝐢𝐥𝐭𝐞𝐫𝐢𝐧𝐠: local recurrence amplifies natural input patterns and suppresses stray activity. This review beautifully argues that sensory cortex itself is a site of memory and prediction. Food for thought on hallucinations!
