Recognizing speech in background noise is a strenuous daily activity, yet most humans can master it. An explanation of how the human brain deals with such sensory uncertainty during speech recognition is to-date missing. Previous work has shown that recognition of speech without background noise involves modulation of the auditory thalamus (medial...
The subcortical sensory pathways are the fundamental channels for mapping the outside world to our minds. Sensory pathways efficiently transmit information by adapting neural responses to the local statistics of the sensory input. The longstanding mechanistic explanation for this adaptive behaviour is that neural activity decreases with increasing...
Data analysis workflows in many scientific domains have become increasingly complex and flexible. To assess the impact of this flexibility on functional magnetic resonance imaging (fMRI) results, the same dataset was independently analyzed by 70 teams, testing nine ex-ante hypotheses. The flexibility of analytic approaches is exemplified by the fac...
Sensory thalami are central sensory pathway stations for information processing. Their role for human cognition and perception, however, remains unclear. Recent evidence suggests an involvement of the sensory thalami in speech recognition. In particular, the auditory thalamus (medial geniculate body, MGB) response is modulated by speech recognition...
Comprehending speech in noise is a difficult daily activity, yet humans master it with the help of a complex neuronal decoding system spread over the cortical hierarchy. Sensory thalami are central sensory pathway stations on this hierarchical ladder. Recent studies have shown that the left ventral auditory thalamus (ventral medial geniculate body:...
Sensory thalami are central sensory pathway stations for information processing. Their role for human cognition and perception, however, remains unclear. Recent evidence suggests a specific involvement of the sensory thalami in speech recognition. In particular, the auditory thalamus (medial geniculate body, MGB) response is modulated by speech rec...

Contrast healthy controls (HC) minus recovered dysphagic patients (FWE-corrected, p < 0.05).
Neurogenic dysphagia frequently occurs after stroke and deglutitive aspiration is one of the main reasons for subacute death after stroke. Although promising therapeutic interventions for neurogenic dysphagia are being developed, the functional neuroanatomy of recovered swallowing in this population remains uncertain. Here, we investigated 18 patie...
In this study, functional magnetic resonance imaging is utilised to explore activation maps of the human auditory pathway in response to stimuli with different ITD and IPD. The goal of this study is to identify the relevant structures in the human auditory pathway, and in particular to disentangle the cortical and the brainstem contribution.

Swallowing consists of a hierarchical sequence of primary motor and somatosensory processes. The temporal interplay of different phases is complex and clinical disturbances frequent. Of interest was the temporal interaction of the swallowing network. Time resolution optimized functional magnetic resonance imaging was used to describe the temporal s...
Nach einem Schlaganfall kommt es haufig zu Schluckstorungen, die in der Akutphase selten
erkannt werden, doch fur die Patienten lebensbedrohlich sein konnen. Wissenschaftler
versuchen, mithilfe funktioneller Bildgebung das Ratsel der Schluckstorungen zu luften –
ein schwieriges Unterfangen bei aspirationsgefahrdeten Patienten. Das Ziel der Forschun...
Early work on representational specificity and recent findings on temporomandibular joint (TMJ) movement representation raise doubts that a specific swallow representation does exist. Additionally, during cortical stimulation TMJ movements and swallowing show a high overlap of representational areas in the primary motor cortex. It has thus been hyp...
Simultaneous reflection masked thresholds (RMTs) were measured for 3 normal-hearing (NH) and 3 hearing-impaired (HI) subjects as a function of reflection delay. All stimuli were presented diotically and dichotically, using a 200 ms long broadband noise (100-50000 Hz) as input signal. For 55 dB-SL direct sound level, NH-listeners showed a binaural s...

I've heard that task complexity, or the effect of difficulty during two different tasks are only seen cortically in fMRI studies, and that subcortical differences between two tasks that differ in difficulty aren't found. Can anybody give me some examples of such studies, and better yet, are there contradictory studies, i.e. studies showing task complexity in subcortical structures, especially the thalamus?
Does anybody know what the average duration of a vowel to vowel formant transition is compared to a consonant to vowel transition?
I'm looking for literature on dyslexics troubles with consonants. I found this one http://www.sciencedirect.com/science/article/pii/0010027795006974 that found that dyslexics confused /t∫a/ with /∫a/ and /pa/ with /fa/ significantly more than did controls.
Does anybody know of any others?
I was recently wondering why I haven't encountered this kind of study before. Since a lot of people record resting state data, wouldn't it be easy to just compare two groups with many subjects: lefties and righties? It might actually give a decent answer to why we have to mention how many left handers we have in our 20 or so subject studies, or why we should avoid having a mix of the two, or even a mix of genders. It would be great if, for example 50 lefties were compared to 50 righties in an rs-paradigm.
