Summary

Prevalence of chronic subjective tinnitus is rising with age and associated with maladaptive oscillatory changes in auditory as well as non-auditory regions of the brain such as the insula and the anterior cingulate cortex which are known to be key points within the salience and distress networks of the brain.Thus, we are conducting a clinical trial by implementing those auditory as well as non-auditory regions into a tomographical neurofeedback Training (ToNF) -protocol. Prior to 12 electroencephalography (EEG) -based ToNF-trainings with 36 older participants using standardized Low Resolution Electromagnetic Tomography Software (sLORETA, Pascual-Marqui 2002), participants' brains will be measured using structural magnet resonance imaging (sMRI) in order to identify potential structural markers for training success (e.g. cortical thickness). Training success will be measured by oscillatory change via EEG before and after the training period as well as by means of follow-up measures. Furthermore, a comprehensive battery of behavioral and psychometric standardized self-report questionnaires will be applied. Based on this multifocal (Insula, dorsal anterior cingulate cortex \& auditory cortex) ToNF we expect oscillatory changes resulting in decreased tinnitus symptoms such as perceived loudness and distress.

Conditions

• Tinnitus, Subjective

Interventions

Type	Name	Description
OTHER	tomographic EEG Neurofeedback Training	EEG-Electrodes are placed on the patients head to record the brain activity, EEG-recordings are processed by the standardized Low Resolution Brain Electromagnetic Tomography algorithm (sLORETA) to calculate the frequency spectrum in the auditory cortex, the insula and the anterior cingulate cortex and deliver feedback for the patient
