Research: brief description
Hana Mala Rytter (publishing as Hana Mala) is Associate Professor in cognitive neuroscience and neuropsychology at the Department of Psychology, University of Copenhagen. Her research focuses on brain organization and reorganization in response to brain injury and brain injury rehabilitation. She has an extensive knowledge and expertise in modeling of cognitive functions through the use of animal models including project design, project management, data analysis and dissemination. As part of the Unit for Cognitive Neuroscience (UCN), Department of Psychology, she has supervised and coordinated parallel research projects, and functioned as ‘lab manager’. She holds a certificate in Laboratory Animal Science complying with the FELASA category C requirements. Her current research focus is on combinatory treatment effects on recovery after brain injury, effects of pharmacological support, and on the mapping of functional architecture related to brain structures (in particular the prefrontal cortex and the hippocampus) and neurotransmitter systems (such as acetylcholine and dopamine). The cognitive domains of special interest to her are spatial memory and problem solving, together with executive functioning. The animal modelling approach is complemented by planned future studies into the human navigational strategies.
Hana Mala Rytter has experience with Health Technology Assessment (area: brain injury rehabilitation) and systematic grading of research literature as well as performing systematic review of literature regarding cognitive rehabilitation after brain injury. She also has experience with applied clinical neuropsychological research including project design, management, data analysis and dissemination. In the years 2011-2014, she has been responsible for research design, data analysis and dissemination of the type I-II study investigating the effect of specialized, interdisciplinary treatment of the persistent post-concussive syndrome. She is currently writing up the results from this study and preparing its sequel, a national multi-centre, type III trial.
Hana Mala Rytter functions currently as Chair of Expert committee for the Association of Brain Injured, Denmark. She has been a member of several committees providing feedback to the Danish authorities in the health and social domain on the treatment standards and guidelines relative to the survivors of brain injury.
