    Behavioural data, illustrated separately for each experimental condition (H50, H100, T50, T100).

    <p>Upper half: Subjective ratings on the dimensions arousal, valence, anxiety, and authenticity. Higher values indicate higher arousal, but positive valence. Lower half: Skin conductance data (range-corrected values). Error bars indicate the standard error of mean (SEM). #NS.SCR: mean number of non-stimulus specific skin conductance reactions; AMP.NS.SCR: mean amplitude of non-stimulus specific skin conductance reactions. * p < 0.05. ** p < 0.01</p

    Correlation analyses.

    <p>Scatterplots display correlations between the estimated beta values in the right anterior insular cortex (MNI coordinates (x = 39, y = 15, z = 3)) and AMP.NS.SCR (range-corrected) in response to H100 (a), subjective arousal ratings for H100 (b), and the Anxiety Sensitivity Index (c). Pearson correlation coefficients (R) are given in the plots. Estimated ß-values for the four regressors of interest (H50, H100, T50, T100) were extracted and added so that the t-contrast H50+H100 > T50+T100 was replicated, i.e. difference values were entered into correlation analyses. ** p < 0.01 (Bonferroni-corrected).</p

    Design of the heartbeat paradigm.

    <p>Upper half: Illustration of the block design structure (four conditions with four blocks of stimulation each, separated by 30 s baseline periods). Order of blocks was randomized across subjects. Lower half: Temporal sequence within one condition, using the example of the heartbeat condition. Hearts illustrate the heartbeat condition; clefs illustrate the sinus tone condition.</p

    Peak voxel and sub regions from the conjunction analysis of the task induced deactivation (TID) during run 1 and relative sAA increase immediately prior to scanning.

    <p>Peakvoxel from the conjunction analysis are based on a voxelwise p<0.005, uncorrected and a minimum cluster size of k = 30. MTG: middle temporal gyrus; STG: superior temporal gyrus; SFG: superior frontal gyrus; MFG: medial frontal gyrus.</p

    <p>Error bars indicate SEM. T0  =  training phase; Prep.  =  MRI preparation (subjects were placed on the MRI table, get goggles, headphones, headcoil, ect.); R1  =  Run 1; Struct.  =  high resolution structural scan; R2  =  Run 2. **p<0.01.</p
