Model-based therapy in aphasia – behavioural and neural effecs


02/2007-07/2010               Model-based therapy: Behavioural modulation in the language network

The project at RWTH Aachen University was funded by the BMBF (grant 01GW0662 to Walter Huber) as part of a larger collaborative project with the Universities of Kiel and Freiburg (Mechanisms of brain reorganisation of the language network, PI Cornelius Weiller, Neurocenter at Freiburg University).
Persons with aphasia after stroke and due to dementia received intensive lexical therapy of their word finding disorders. Therapy-induced changes of brain activation were determined considering fMRI-measurements before versus after therapy, and these were again compared to according activation changes in healthy participants.

The habilitation thesis offers an overview of the publications of this and other projects 2007-2011.
