On Thursday 21 October at 14:00, Timo Lehmann Kvamme defends his PhD dissertation entitled "Neurofeedback control of the neural correlates of multisensory perception".
A new Ph.D. project from Aarhus University investigates “neurofeedback”, a psychophysical process in which brain activity is measured in real-time and presented to the individual thereby allowing them to self-regulate their own brain activity with resulting effects on behavior and cognition.
The defense will describe an attempt to use real-time MEG-neurofeedback to alter the ratio of alpha activity between the different hemispheres in the parietal cortex. We reveal that this MEG-neurofeedback training can alter multisensory experiences in the sound-induced flash illusion task, but that the effect depended on the prior trial’s multisensory congruency, consistent with a Bayesian causal inference account of multisensory integration.
In a review of empirical neurofeedback studies, the prevailing conception that neurofeedback can reveal causal links between brain activity and cognitive functions was investigated. We argue that this inference may not always be valid and that neurofeedback may also indirectly affect cognitive processes via changes in other brain activities.
The extent to which individuals are aware of the purpose of the neurofeedback experiment was investigated using a novel contingency awareness questionnaire. Results indicated that some subjects can gain a degree of awareness of the purpose of experimental purposes thereby questioning whether clinical neurofeedback studies can be performed in a double-blinded manner.
The summary is written by the PhD student.
The defence is public and takes place in Store Anatomisk Auditorium, Building 1232, Aarhus University, Wilhelm Meyers Allé 3, 8000 Aarhus C. Please read the attached press release for more information.
