Semantic Cognition Lab
Welcome to the Semantic Cognition Lab
Our team investigates how concepts and language meaning are encoded in the brain. We use functional brain imaging (fMRI and MEG), transcranial magnetic stimulation, and behavioral assessment of neurological patients and healthy participants. A current focus of our work is the application of fMRI, semantic modeling and machine learning techniques to investigate how word meaning is represented in high-level association areas of the cortex and how these representations relate to sensory-motor and affective neural systems. The ultimate goal is to elucidate the representational code for conceptual knowledge, leading to advancements in artificial intelligence and brain-machine interface technology, as well as to a deeper understanding of the language and memory deficits caused by neurological disorders.
We are part of the Medical College of Wisconsin, affiliated with the Department of Neurology, the Joint Department of Biomedical Engineering, the Neuroscience Research Center, and the doctoral programs in Neuroscience and Biophysics.

Featured studies
A neural map of word meaning
We asked which areas of the cerebral cortex represent information about the meanings of words. Previous studies had indicated that large portions of the temporal, parietal, and frontal lobes participate in processing language meaning, but it was unknown which regions actually encoded information about individual word meanings.
The stuff of thought
In this study, we addressed the question of how the contents of our thoughts – concepts, ideas, beliefs – are related to the physical world that we experience through our senses by evaluating six different models of concept representation.
