As a key oscillatory activity in the brain, thalamic spindle activities are long believed to support memory consolidation. However, their propagation characteristics and causal actions at systems level remain unclear. Using functional MRI (fMRI) and electrophysiology recordings in male rats, we found th...
We used Magnetic Resonance Imaging (MRI) data of the Human Connectome Project (HCP), U100 dataset (HCP900 data release), which includes 100 unrelated healthy adults (“h-HCP” dataset, 36 females; mean age = 29.1 ± 3.7 years)65. All experiments were reviewed and approved by t...

相反,在相对年轻的双侧颞叶癫痫患者中使用静息态功能MRI,Liao及其同事在发作间期观察到了更随机的拓扑结构。可能不仅癫痫表型,而且连接测量的模态也部分解释了其中的一些差异。事实上,由于当前的结果是基于功能连接网络的功能MRI和结构连接网络的弥散...
Figure 4. Viewed from the side, a short bore MRI is half the length of a standard MRI, which means your whole body does not have to be inside the scanner, just the area being imaged. Open MRI:this machine is designed more like a bagel sliced in half rather than a donut hole. It ...
and the LMS method was applied to compare between groups and time points. Box charts present the dispersion and the shape of the data distribution for the test value in the compared populations. The length of the bars is equal to the quarter range (Q1–Q3) of the data, the tips of the...
Nevertheless, DCE-MRI is not routinely used in cSVD studies due to practical impediments (long scan time, exogenous contrast), lack of widespread expertise, and technical and physiological complexities and confounds [100], [101]. There are few studies of BBB permeability change over time in ...
Scan time and frame length were designed according to the radiotracer characteristics. Dynamic PET frames were realigned using AIR 5.2.5[67]. T1- and T2-weighted structural MRI were acquired on four different Siemens scanners with standard parameters. All structural MRIs (T1 and T2) were un...

Functional networks were reconstructed using fMRI data from the same individuals. fMRI volumes were corrected for physiological variables, including regression of white matter, cerebrospinal fluid, and motion. fMRI time series were...
INT is commonly investigated in cellular4,24and systemic1,12,13,14,22,25,26granularity levels. On a systemic level, Hasson and colleagues1,12,26,27operationalize INT using functional connectivity during task state. They define temporal receptive windows as “the length of time before a response...
