How does the brain make meaning?
We study concepts, language, and the neural systems that let us understand the world.
01 / Research
Meaning is a whole-brain achievement.
DeLab investigates the brain bases of language, especially meaning and semantics. We ask how concepts are represented, how language draws on perception and action, and what changes when these systems are affected by disease or injury.
Our current questions ↓Concepts & semantics
How are concepts represented and processed in the brain? We examine the relation between conceptual knowledge and perception–action systems.
Language in the wild
We study how the brain processes time, space, action, metaphor, and naturalistic language.
Brain health & recovery
Our work examines semantic processing in stroke and Parkinson’s disease, with an eye toward improving outcomes.
NeuroAI
Brains and language models, in conversation.
We study what large language models can reveal about human conceptual knowledge—and where their representations meaningfully diverge from the brain.
How we work
From behavior to brain networks.
We connect complementary methods to answer questions at multiple levels of analysis.
- Functional MRI fMRI
- Lesion-symptom mapping
- Transcranial stimulation TMS / tDCS
- Computational modeling
- Behavioral studies
