Dense array electroencephalography ((d)EEG), which provides a non-invasive window for measuring brain activity and a temporal resolution unsurpassed by any other current brain imaging technology¹, ² is being used increasingly in the study of social cognitive functioning in infants and adults. While (d)EEG is enabling researchers to examine brain activity patterns with unprecedented levels of se...

Advances in human brain neuroimaging for high-temporal and high-spatial resolution will depend on localization of Electroencephalography (EEG) signals to their cortex sources. The source localization inverse problem is inherently ill-posed and depends critically on the modeling of human head electromagnetics. We present a systematic methodology to analyze the main factors and parameters that af...

Learning is not a unitary phenomenon. Rather, learning progresses through stages, with the stages reflecting different challenges that require the support of specific cognitive processes that reflect the functions of different brain networks. A theory of general learning proposes that learning can be divided into early and late stages controlled by corticolimbic networks located in frontal and ...

perception of quality of life (QOL) of institutionalized older adults tend to decline with the passage of time. Depression is the most commonly reported psychological problem among institutionalized older adults, ranging in prevalence from 22.2% to 81.8% (Chow et al., 2004; Demet, Taskin, Deniz, Karaca, & Icelli, 2002; Lin, Wang, & Huang, 2007; Mohd Aznan & Samsul, 2007). Osness and Mulligan (1...

Working memory (WM) is one of the most studied cognitive constructs. Although many neuroimaging studies have identified brain networks involved in WM, the time course of these networks remains unclear. In this paper we use dense-array electroencephalography (dEEG) to capture neural signals during performance of a standard WM task, the n-back task, and a blend of principal components analysis an...

BrainK is a set of automated procedures for characterizing the tissues of the human head from MRI, CT, and photogrammetry images. The tissue segmentation and cortical surface extraction support the primary goal of modeling the propagation of electrical currents through head tissues with a finite difference model (FDM) or finite element model (FEM) created from the BrainK geometries. The electri...

Electroencephalographic (EEG) oscillations in multiple frequency bands can be observed during functional activity of the cerebral cortex. An important question is whether activity of focal areas of cortex, such as during finger movements, is tracked by focal oscillatory EEG changes. Although a number of studies have compared EEG changes to functional MRI hemodynamic responses, we can find no pr...

This study assessed the diet quality and nutritional status of beneficiaries of Adolescent Girl scheme, a national programme targeted towards their nutrition/health needs. 209 girls (aged 11-21 years) from six rural blocks - Delhi (Alipur, Kanjhawala and Mehrauli), Haryana (Madhosinghana), Rajasthan (Deeg) and Uttar Pradesh (Fatehpur Sikri) comprised the sample. Weight and height were measured ...
