“…We converted all of the corresponding electrodes to the standard Montreal Neurological Institute (MNI) coordinates using a probabilistic estimation method. 32,33 We estimated the anatomical labels according to the Association between central obesity and EF as assessed by stroop task performance MNI coordinates of all the corresponding electrodes, and found that the activated channels were located above the bilateral FPA (CH6 and 11 for the left, CH13 and 16 for the right), bilateral DLPFC (CH5 and 7 for the left, CH14 and 15 for right) and bilateral VLPFC (CH3 and 4 for the left, CH19 and 20 for the right). Based on the concentration change of oxy-Hb during the Stroop task, we calculated the oxy-Hb interference in these brain regions.…”

Recent studies have suggested a link between executive function (EF) and obesity. Studies often adopt body mass index (BMI), which re°ects the distribution of subcutaneous fat, as the sole marker of obesity; however, BMI is inappropriate to distinguish central obesity, which indicates the centralized distribution of visceral fat. Visceral fat compared with subcutaneous fat represents greater relative lipid turnover and may increase the risk of cognitive decline in older adults. However, the relationship between EF and central obesity is largely unknown, particularly in young adults. Therefore, we used waist circumference (WC) as a marker of central obesity and investigated di®erent sensitivities between BMI and WC in the brain function. A total of 26 healthy young adults (aged 18-25 years; 42% female) underwent functional near-infrared spectroscopy assessments. EF was assessed using the Stroop task, which is a classical measurement of EF. A signi¯cant Stroop e®ect was observed in the behavioral and hemodynamic data. In addition, we observed that behavioral interference on the Stroop task varied much more in subjects with higher BMI and WC than those subjects with lower. Elevated BMI and WC were associated with a decreased hemodynamic response during the Stroop task speci¯cally in the prefrontal cortex (PFC). Compared to BMI, WC was more closely connected with inhibitory control and revealed right lateralized PFC activation. Our¯ndings suggest that WC is a reliable indicator of brain function in young adults and propose a relationship between EF and central obesity.

“…To have an accurate human brain template for use with AVC, we chose a subject-averaged brain template (i.e., ICBM 152) 31 along with the AAL 116 template 32 to mark the brain ROIs. Thus, the graph formation was guided by the anatomical structure of the brain.…”

“…First, the predesigned ICBM152 brain template including 176,192 voxels was generated using the MRI structure scan, an average brain image taken from 152 subjects. 31 The size of the brain template was 229 × 192 × 192 mm 3 . A careful segmentation was performed to separate the scalp, skull, gray, and white matters.…”

Automated voxel classification used with atlas-guided diffuse optical tomography for assessment of functional brain networks in young and older adults

Abstract. Atlas-guided diffuse optical tomography (atlas-DOT) is a computational means to image changes in cortical hemodynamic signals during human brain activities. Graph theory analysis (GTA) is a network analysis tool commonly used in functional neuroimaging to study brain networks. Atlas-DOT has not been analyzed with GTA to derive large-scale brain connectivity/networks based on near-infrared spectroscopy (NIRS) measurements. We introduced an automated voxel classification (AVC) method that facilitated the use of GTA with atlas-DOT images by grouping unequal-sized finite element voxels into anatomically meaningful regions of interest within the human brain. The overall approach included volume segmentation, AVC, and cross-correlation. To demonstrate the usefulness of AVC, we applied reproducibility analysis to resting-state functional connectivity measurements conducted from 15 young adults in a two-week period. We also quantified and compared changes in several brain network metrics between young and older adults, which were in agreement with those reported by a previous positron emission tomography study. Overall, this study demonstrated that AVC is a useful means for facilitating integration or combination of atlas-DOT with GTA and thus for quantifying NIRS-based, voxel-wise resting-state functional brain networks.

Diffuse optical tomography (DOT) is a variant of functional near infrared spectroscopy and has the capability of mapping or reconstructing three dimensional (3D) hemodynamic changes due to brain activity. Common methods used in DOT image analysis to define brain activation have limitations because the selection of activation period is relatively subjective. General linear model (GLM)-based analysis can overcome this limitation. In this study, we combine the atlas-guided 3D DOT image reconstruction with GLM-based analysis (i.e., voxel-wise GLM analysis) to investigate the brain activity that is associated with risk decision-making processes. Risk decision-making is an important cognitive process and thus is an essential topic in the field of neuroscience. The Balloon Analog Risk Task (BART) is a valid experimental model and has been commonly used to assess human risk-taking actions and tendencies while facing risks. We have used the BART paradigm with a blocked design to investigate brain activations in the prefrontal and frontal cortical areas during decision-making from 37 human participants (22 males and 15 females). Voxel-wise GLM analysis was performed after a human brain atlas template and a depth compensation algorithm were combined to form atlas-guided DOT images. In this work, we wish to demonstrate the excellence of using voxel-wise GLM analysis with DOT to image and study cognitive functions in response to risk decision-making. Results have shown significant hemodynamic changes in the dorsal lateral prefrontal cortex (DLPFC) during the active-choice mode and a different activation pattern between genders; these findings correlate well with published literature in functional magnetic resonance imaging (fMRI) and fNIRS studies.
