(a) Whole-brain T1-weighted study template showing the anatomical localisation of the hypothalamus. (b) Anatomical mask of the hypothalamus. (c) Brain activity was recorded during alternating …
Complete set of specific spatially independent components as used for connectivity-based analyses in this study. Not shown are six components that were identified as noise.
(a) Anatomical subdivisions of the human hypothalamus as based on post-mortem anatomical studies (Dudás, 2013). Left: Hypothalamic regions in ventro-caudal direction. Right: Hypothalamic zones in …
(a–e) Left: Individual hypothalamic centres derived from functional connectivity presented as mixture model thresholded probability maps. Centre: Normalised spectral BOLD signal changes (n = 22, …
Left: Cardiovascular centres in the hypothalamus defined by functional connectivity (Figure 2). (a) right anterior right LH/SON; (b–c) bilateral tuberal LH/SON; (d) tuberal PVN; (e) arcuate nucleus. …
Segmentation is based on a masked independent component analysis of functional MRI data. The components were coloured to highlight the anatomical subdivisions of the human hypothalamus (Figure …
(a–e) First column: Individual cardiovascular hypothalamic regions presented as mixture model thresholded probability maps as derived from the main analysis (Figure 2). Second column: matched …
(a–e) Left: Individual cardiovascular hypothalamic regions presented as mixture model thresholded probability maps. Right: functional connectivity maps of the respective region, calculated using …
(a–e) Individual hypothalamic centres derived from functional connectivity presented as mixture model thresholded probability maps. These five centres fulfilled both criteria for cardiovascular …
(a) Three of the five hypothalamic cardiovascular centres derived from functional connectivity (Figure 2), namely PVN/PH (top), anterior LH/SON (middle), and arcuate nucleus (bottom) were also …
(a) Hypothalamic component encompassing the paraventricular nucleus and the posterior hypothalamic area. (b) Detail of the connectivity changes of (a) during LBNP that includes the rostral …

Note that the reference scans for unwarping (Reference SE (no SMS; AP and PA)) are the same sequence but with inverted phase encoding direction. Hence, they are summarised in one table here. However, both sequences need to be acquired for estimating the susceptibility induced field.
