Friedmann Pulvermueller

Freie Universität Berlin
Participates in 2 items

Friedemann Pulvermueller is Professor of Neuroscience of Language and Pragmatics and Head of the Brain Language Laboratory of the Freie Universität Berlin. His main interest is in the neurobiological mechanisms enabling humans to use and understand language. His team accumulated neurophysiological, neuroimaging and neuropsychological evidence for category-specific semantic circuits distributed across a broad range of cortical areas, including modality-specific ones, supporting correlation-based semantic learning and grounding mechanisms. His focus is on active, action-related mechanisms crucial for symbol understanding.

Large Language Models & Multimodal Grounding

Neural networks can be used to increase our understanding of the brain basis of higher cognition, including capacities specific to humans. Simulations with brain-constrained networks give rise to conceptual and semantic representations when objects of similar type are experienced, processed and learnt. This is all based on feature correlations. If neurons are sensitive to semantic features, interlinked assemblies of such neurons can represent concrete concepts. Adding verbal labels to concret...
