We provided a quality-control database for the
resting-state data of the young-adult human connectome project. We showed how
to exploit the database to select subjects/scans with opposite noise
characteristics, suitable for benchmarking denoising pipelines.

correlations between a subset of the extracted QC metrics. The correlation
matrix was obtained considering the whole HCP dataset.
Figure 3. The box plots show the
distributions of some representative QC metrics for the two
samples of LM and HM subjects (n=250 in each sample). The criteria for sample
definition was based on the extreme values of the CensFDDVARS distribution (first

After breath training,
the treatment IMT shows less activation clusters with less activation strength
compared to the sham IMT. Our results agree with previous meditation studies including breathing training, showing
that DMN is deactivated and network gets more organised and localised

We investigate if brain coherence reduction is a modality-specific effect, by comparing BOLD signal during rest and a continuous auditory or visual task. Our results suggest that task-induced reduction in brain coherence occurs only in default-mode and hetero-modal brain regions.

reduced. Language network and dorsal-visual network were identified during AS
and VS, respectively. Maps were thresholded at a voxel threshold of p <

The results described demonstrate that locus coeruleus (LC) activation is associated with switching between brain states. Consequently, they provide potential insight into LC functionality and its relationship with latent brain states.
Figure 2. Latent brain states identified from the HMM. Compared to the other states, S1 shows increased DMN activity while S2 shows increased DAN and SN activity. S3 appears to be a transition state consistent with that presented in literature11, and S4 is prevalent during the squeeze blocks of the paradigm. DMN - default mode network; FPCN - fronto-parietal control network; DAN - dorsal attention network; SN - salience network; LC - locus coeruleus.

Aberrant dynamic FNC is a fundamental feature of brain dysfunction in cirrhotic patients without OHE, which is associated with neurocognitive decline. Dynamic FNC analysis may be a promising avenue in generating new insights into cirrhosis-related neuropathological processes.
Figure 2. Left column indicates the FNC matrices of States 1-4, with the number of windowed FNCs in every state, the corresponding percentage, as well as the number of participants from every group who entered into the state. Right column represents the visualization of functional network connectivity in each state. The functionalconnectivity matrix was screened using a threshold of 0.1 to display all independent components of functional networks. HC, healthy control; PA, cirrhotic patient.

Hemifacial spasm (HFS) is a motor disorder. The
purpose of this study was to investigate the functional alterations of the cortical-striatal
network in HFS using resting-state fMRI. To sum up, these data suggest that HFS may lead to an alteration of
neural activity of the cortical-striatal
loop.
Fig. 1: Differences of the
cortical-striatal FC in patients with HFS compared to healthy controls. The FC
between striatal subregions and both motor and emotion-related cortex was
statistically different between the two groups (GRF correction, voxel P < 0.005,
cluster P < 0.05). The yellow dots in the brain represent the seeds of
striatal subregions. The red regions represent the increased FC between seeds
and cortexes, while the blue areas represent a decreased FC. The color bar
