Potential fMRI correlates of 40-Hz phase locking in primary auditory cortex, thalamus and midbrain

I Steinmann, A Gutschalk - Neuroimage, 2011 - Elsevier
MEG and BOLD fMRI are both related to post-synaptic activity, but not all components of the
MEG appear to be equally reflected by the BOLD response. To evaluate potential BOLD …

[HTML][HTML] Detection of transcranial alternating current stimulation aftereffects is improved by considering the individual electric field strength and self-rated sleepiness

Stimulus dependence of contralateral dominance in human auditory cortex

A Gutschalk, I Steinmann - Human brain mapping, 2015 - Wiley Online Library
The auditory system is often considered to show little contralateral dominance but physiological
reports on the contralateral dominance of activity evoked by monaural sound vary widely…

Sustained BOLD and theta activity in auditory cortex are related to slow stimulus fluctuations rather than to pitch

I Steinmann, A Gutschalk - Journal of Neurophysiology, 2012 - journals.physiology.org
Human functional MRI (fMRI) and magnetoencephalography (MEG) studies indicate a pitch-specific
area in lateral Heschl's gyrus. Single-cell recordings in monkey suggest that …

[HTML][HTML] Reduced alpha amplitudes predict perceptual suppression

E Poland, A Bhonsle, I Steinmann, M Wilke - Scientific Reports, 2021 - nature.com
The amplitude of prestimulus alpha oscillations over parieto-occipital cortex has been shown
to predict visual detection of masked and threshold-level stimuli. Whether alpha activity …
