Figure S2.Flowchart for the construction of a weighted functional connectivity network (FCN).(1)We extracted the time series from resting-state fMRI data using a prior anatomically automatic labeling(AAL)template(including AAL-90 an...
split-half亚组在拓扑组织上功能连接网络和结构连接网络都是相似的.目视检查显示,这些亚组的连接模式相似.此外,比较两个健康对照亚组(hc1和hc2),我们观察到加权网络显著相关(aal-90功能连接网络和结构连接网络分别为r = 0.9495和aal-1024功能和结构连接网络分别为r = 0.9659;r = 0.8795和r =...
The sections below are organized according to the phases of the scientific method. First, we consider observations that motivate research on sex differences in human brain anatomy. We organize these observations into four groups: (1) concepts from evolutionary theory (i.e., potential distal causes ...
Brain-age gap in non-LAC datasets Using the same data split ratio, we trained and tested the models in non-LAC datasets. As shown in Figs. 2b and 3b, our models predicting brain age yielded considerable goodness of fit (fMRI: R2 = 0.40, P < 0.001, f2 = 0.67; EEG: ...
As in most peptides, a signal peptide is first split off to produce proghrelin, which is then cleaved by a protein convertase into the active peptide and a fragment, from which obestatin is derived (see the chapter on obestatin in this section of the book). For every step, there is a...
Cellular compartmentation of metabolism: Labeling patterns of glutamate and glutamine. (A) Magnetic resonance spectroscopy (MRS) has the advantage that labeled carbons can be identified and the extent of their labeling quantified in brain in vivo, thereby allowing real-time assessment of metabolic ...
Since the left half of the brain controls the comprehension and expression of (non-emotional) language, split-brain patients are unable to name objects placed in the left hand, and they fail to report the presence of a moving or stationary stimulus in the left half of their visual fields (...
While the link between brain structure and function remains an ongoing challenge, the prevailing hypothesis is that the structure-function relationship may itself be gradually decoupling from unimodal to transmodal cortex. However, this hypothesis is con
Replay, first identified in the rodent hippocampus during sleep1,2, has subsequently been observed during wakeful rest and while on-task, and is now considered to serve a broad spectrum of cognitive functions13,14. Initial studies suggested that replay (during sleep) plays a crucial role in co...
(a) For leave-one-out cross-validation the functional connectivity (S) was computed for every subject i and these data were split into a training and a test set. (b) Calculation of an FSIQ-weighted group connectivity matrix (M) to enhance differences in intelligence-related features in the...
