Research: brief description

The overreaching research topics of Jesper Mogensen are the neurocognitive organization and reorganization of the normal and injured/disease affected brain as well as neuroplasticity (with special emphasis on experience-associated neuroplasticity). These topics are addressed utilizing a broad spectrum of experimental as well as theoretical approaches. Experimental approaches include an extensive use of animal models (with special emphasis on traumatic brain injury and cognitive/behavioural processes associated with problem solving). But the experimental work also includes human studies addressing normal neurocognitive processes and the consequences of brain injury as well as the posttraumatic processes associated with cognitive and neural reorganizations. At the theoretical level the development and utilization of the neurocognitive REF (Reorganization of Elementary Functions) model has been in focus. The point of departure when developing the REF-model was the apparent contradictions between functional localization and posttraumatic functional recovery (e.g. Mogensen & Malá, 2009). The REF-model has, however, subsequently been developed into a more general account of neurocognitive mechanisms in both the normal and injured brain (e.g. Mogensen, 2014, 2015). Furthermore, a next step has been taken by applying the mechanisms described by the REF-model to the areas of perception and conscious awareness – leading to the development of the REFCON-model (e.g. Overgaard & Mogensen, 2014, 2015). Ongoing research is presently developing REF-model based neurocognitive modelling (including mathematical modelling) of additional neurocognitive domains. Thus, the REF-model not only provides a novel basis for the understanding of and clinical developments within neurorehabilitation (especially of patients suffering acquired brain injury) – it also provides a novel approach to the understanding of neurocognitive organization and reorganization of the normal brain. Additionally, the development of the REF and REFCON models represent examples of the ways in which basic research primarily conducted in animal models provides insights which in a translational manner creates a novel approach to and understanding of both pathological and normal processes in humans.

 

In parallel to the above-described theoretically and modelling-oriented projects the research of Jesper Mogensen includes a broad spectrum of more “applied research”-oriented projects. Numerous research lines address issues related to the development of therapeutic methods within the area of acquired brain injury. Some research lines address the development of novel pharmacological agents (novel application of pre-existing drugs (such as erythropoietin (EPO)) and the development of newly synthesized agents as pharmaceutical agents). Other research lines address the utilization of activation-based methods (such as physical exercise) as well as various types of environmental enrichment in the therapeutic interventions after acquired brain injury. The optimal timing and intensity of posttraumatic cognitive rehabilitative training constitute another research line. In collaboration with clinical units (for instance the member units of ReCBIR (Research Centre for Brain Injury Rehabilitation – of which Jesper Mogensen is the Director)) Jesper Mogensen address a number of the same issues in brain injured patient-populations. As research coordinator for the Centre of Rehabilitation of Brain Injury, Jesper Mogensen presently heads and coordinates clinical studies developing and evaluating clinical therapeutic methods in brain injured patients.

 

The mentioned collaborations within ReCBIR are far from the only collaboratively organized research activities of Jesper Mogensen. Two prominent examples of such activities are the University of Copenhagen Centre of Excellence ProGram (of which Jesper Mogensen is co-PI) and the interdisciplinary research organization (with Jesper Mogensen as PI) DINEA (Danish Integrative Neurorehabilitation Alliance). The research of ProGram focuses on the neurocognitive mechanisms of linguistic processes with special emphasis on grammar. The theoretical basis of this research is an integration of on the one hand a newly developed linguistic theory of grammar and on the other hand the REF-model. The research of DINEA constitutes highly interdisciplinary (ranging from philosophy via cognitive science and cognitive neuroscience to neuroimaging and molecular biology) studies of the neurocognitive organization of the brain. The theoretical basis for the research of DINEA is the REF and REFCON models.
