Neurocomputation: Theory and brain-grounded neurocomputational modelling

About

We use neuroanatomically and neurophysiologically inspired network models to address questions about language and cognition. These networks mimic the structure and connectivity of the language areas and sensorimotor systems of the human cortex to model language learning and breakdown due to lesions. The networks help explain established knowledge about specific neurocognitive and –linguistic brain activations and offer new experimental predictions to be addressed in neuroimaging experiments or patient studies.

Projects

MatCo - Material Constraints Enabling Human Cognition

The new project "MatCo-Material Constraints Enabling Human Cognition" will start in autumn.

The project “MatCo” led by Prof Pulvermüller at the Freie Universität Berlin will use novel insights from human neurobiology translated into mathematically exact computational models to find new answers to long-standing questions in cognitive science, linguistics and philosophy. Models replicating structural differences between human and non-human primate brains will help delineate mechanisms underlying specifically human cognitive capacities. Key experiments will validate critical model predictions and new neurophysiological data will be applied to further improve the biologically-constrained networks.

This project is founded by the European Research Council (ERC).

Matters of Activity (MoA)

Why are humans capable of acquiring a large number of symbols, and what are the neural material features critical for this extraordinary ability? Here we will explore the material basis of symbols in the human brain by means of brain-inspired neural models constrained by cortical neuroanatomy, function and obeying well-established neuroscience principles (see figure). The subproject »exploring the material basis of symbols« aims to explain the cognitive activity (language, symbols, thought) by the structural features of the underlying neural matter present in the human brain, with the ultimate goal to generate brain simulator mimicking essential symbol processing functions with its application to specific healthy and patient brains.
Over and above neurocomputational simulations, neuroimaging and neuropsychological studies (using EEG, TMS, and/or fMRI) will be carried out to determine the neurobiological correlates of linguistic-conceptual and visual-gestalt-like symbolic processes in the human brain. Results will be compared with predictions generated by the neurocomputational model.

BABEL: Bio-inspired Architecture for Brain Embodied Language – Berlin part

Previous research in behavioural and cognitive neuroscience demonstrates a close link between the brain systems for language, action and perception. These parallel developments in behavioural and computational neuroscience, as well as in cognitive robotics and in neuromorphic engineering constitute a timely opportunity to synergistically integrate the interdisciplinary methods and approaches from these fields with the aim of furthering the scientific and technological progress in language pro-cessing in natural and artificial cognitive systems. The project proposes the interdisciplinary integration of new brain imaging experiments, of neuro-anatomical computational and neuromorphic studies, and of humanoid robotics experiments in order to characterise the brain mechanisms supporting language learning in an embodied and pragmatic (situated) context, and to design and test novel brain-inspired neural technologies for action and language learning experiments with interactive intelligent systems such as humanoid robots.
