INTRODUCTION: The determination of the tinnitus pitch-match (PM) frequency is not straightforward but an important audiological assessment recommended for clinical and research purposes. We evaluated repetitive recursive matching using an iPod-based matching procedure as a method to estimate a patient's PM frequency without audiometric equipment. METHODS: One hundred and seventeen patients with chronic tonal tinnitus (uni- and bilateral tinnitus) measured their tinnitus in 10 sessions using a se...

Abstract Tinnitus describes the perception of a sound without external source and is characterized by high comorbidity, e.g. depression. In many studies, tinnitus patients were compared to healthy controls while a comorbid psychiatric diagnosis was an exclusion criterion. Consequently, patients with severe tinnitus and psychiatric comorbidity were often neglected. In the current study, we tried to fill this gap and compared four groups including two control groups: (1) chronic tinnitus patients ...

The present study used resting state MEG whole-head recordings to identify how chronic tonal tinnitus relates to altered functional connectivity of brain’s intrinsic cortical networks. Resting state MEG activity of 40 chronic tinnitus patients and 40 matched human controls was compared identifying significant alterations in intrinsic networks of the tinnitus population. Directed functional connectivity of the resting brain, at a whole cortex level, was estimated by means of a statistical compari...

Previous neuroimaging studies have shown that sounds can be discriminated due to living-related or man-made-related characteristics and involve different brain regions. However, these studies have mainly provided source space analyses, which offer simple maps of activated brain regions but do not explain how regions of a distributed system are functionally organized under a specific task. In the present study, we aimed to further examine the functional connectivity of the auditory processing pat...

Abstract Chronic tinnitus, a symptom of high prevalence, is a persistent hearing sensation in the absence of an external sound source. Recent electrophysiological studies indicate that tinnitus generation is to a high degree the result of maladaptive plasticity in the central auditory pathway. The pitch of the tinnitus sensation can be assessed by performing a pitch matching procedure. In the most frequent “tonal tinnitus” type pure tones are used as test stimuli. However, in the case of tonal t...

Objective Dysphagia is a frequent and outcome-relevant complication of various neurological disorders, whose treatment options are still limited. Lately, neuromodulatory treatment devices have come into focus to enhance adaptive plasticity in the cortical swallowing network. However, performing neurophysiological and functional imaging studies to investigate these novel neurostimulation techniques for the treatment of neurogenic dysphagia in severely affected patients is difficult. Therefore, ba...

Information in the cortex is encoded in spatiotemporal patterns of neuronal activity, but the exact nature of that code still remains elusive. While onset responses to simple stimuli are associated with specific loci in cortical sensory maps, it is completely unclear how the information about a sustained stimulus is encoded that is perceived for minutes or even longer, when discharge rates have decayed back to spontaneous levels. Using a newly developed statistical approach (multidimensional clu...
