High-frequency oscillations (HFOs) are a promising biomarker for the epileptogenic zone. It has not been possible, however, to differentiate physiological from pathological HFOs, and baseline rates of HFO occurrence vary substantially across brain regions. This project establishes region-specific normative values HFOs high-frequency activity (HFA).Intracerebral stereo-encephalographic recordings with channels displaying normal nonlesional tissue were selected 2 tertiary epilepsy centers....

Aerosols resulting from the combustion of acetylene, wood, and JP-4 aviation fuels have been characterized in both laboratory larger field scales by activity as cloud condensation nuclei (CCN), total particle or (CN) count, ion chromatography (IC) on filter samples, morphology scanning electron microscopy. The CCN / CN ratio for a given aerosol sample is quantitative indicator ability to become involved atmospheric removal nucleation scavenging. On scales, this was range 0.2–1.0 wood...
Regional variations in oscillatory activity during human sleep remain unknown. Using the unique ability of intracranial electroencephalography to study situ brain physiology, this assesses regional electroencephalographic and creates first atlas using recordings from cycle.Intracerebral with channels displaying physiological nonlesional tissue were selected 91 patients 3 tertiary epilepsy centers. Sections non-rapid eye movement (stages N2 N3) rapid (stage R) cycle for nonoscillatory signal...
The Cuban Human Brain Mapping Project (CHBMP) repository is an open multimodal neuroimaging and cognitive dataset from 282 young middle age healthy participants (31.9 ± 9.3 years, range 18-68 years). This was acquired 2004 to 2008 as a subset of larger stratified random sample 2,019 La Lisa municipality in Habana, Cuba. exclusion criteria included the presence disease or brain dysfunctions. Participant data that being shared comprises i) high-density (64-120 channels) resting-state...
We present an extension to the Brain Imaging Data Structure (BIDS) for motion data. Motion data is frequently recorded alongside human brain imaging and electrophysiological The goal of Motion-BIDS make interoperable across different laboratories with other modalities in behavioral research. To this end, standardizes format metadata structure. It describes how document experimental details, considering diversity hardware software systems This promotes findable, accessible, interoperable,...
Neuroimaging has been facing a data deluge characterized by the exponential growth of both raw and processed data. As result, mining massive quantities digital collected in these studies offers unprecedented opportunities become paramount for today's research. neuroimaging community enters world "Big Data", there concerted push enhanced sharing initiatives, whether within multisite study, across studies, or federated shared publicly. This article will focus on database processing ecosystem...
Abstract The transport of reactive trace gases by stationary planetary scale waves has been investigated with the aid Matsuno's wave model (1970) and linear eddy equation derived from tracer continuity equation. It is shown that, for fluxes, K‐theory fields, as introduced Reed German (1965), may be defined. These become matrix fields when photochemical coupling effects are considered. flux a particular gas related to gradients mean concentrations other chemically coupled gases, well its own...
Data sharing is becoming more of a requirement as technologies mature and global research communications diversify. As result, researchers are looking for practical solutions, not only to enhance scientific collaborations, but also acquire larger amounts data, access specialized datasets. In many cases, the realities data acquisition present significant burden, therefore gaining public datasets allows robust analyses broadly enriched exploration. To answer this demand, Montreal Neurological...
Measurements of condensation nuclei (CN) and cloud (CCN) were obtained from aircraft penetrations controlled burns chaparral, pine forest, a JP‐4 (jet fuel) pool fire. Vegetative gave rise to large numbers CN, most which also CCN at supersaturation less than 1%. This is be contrasted with the much lower activity smoke only 1–2% under identical conditions. The field observations are consistent laboratory results conditions simulate natural clouds. implies that although droplets readily grow...
Nonseasalt sulfate (nss SO42-) mass concentrations, cloud condensation nuclei (CCN) number and droplet concentrations in warm cumulus stratocumulus clouds were simultaneously measured situ marine air masses on El Yunque peak Puerto Rico. Our results show that CNN (measured at 0.5% supersaturation) nss SO42- (in the range of ~ 400–1700 ng m-3) are significantly correlated this site. Droplet studied do not a discernible trend with 300–1400 m-3). In clouds, small increase concentration 300–1100...
Cloud condensation nuclei (CCN) measurements within stratus clouds that have involved droplet separation revealed a clear preference for activation on the with lowest critical supersaturations (Sc). When droplets of various sizes were separated from sample, consistent relationship between cloud size and nucleus Sc was discovered—large tend to grow large (low Sc) vice versa. Interpretation in terms modes mixing dry environment demonstrates homogeneous process.
The Tomographic Quantitative Electroencephalography (qEEGt) toolbox is integrated with the Montreal Neurological Institute (MNI) Neuroinformatics Ecosystem as a docker into Canadian Brain Imaging Research Platform (CBRAIN). qEEGt produces age-corrected normative Statistical Parametric Maps of EEG log source spectra testing compliance to database. This was developed at Cuban Neuroscience Center part first wave Human Mapping Project (CHBMP) and has been validated used in different health...
Abstract In January 2016, the Montreal Neurological Institute-Hospital (The Neuro) declared itself an Open Science organization. This vision extends beyond efforts by individual scientists seeking to release datasets, software tools, or building platforms that provide for free dissemination of such information. It involves multiple stakeholders and infrastructure considers governance, ethics, computational resourcing, physical design, workflows, training, education, intra-institutional...
Abstract We describe a model for stratospheric tracers in which transport consists of advection by the mean diabatic circulation and chemical eddy arising from longitudinal variations situ sources sinks. The ozone distribution is reproduced well all species show interesting with longitude. limitations are discussed; we speculate that most important these neglect transient contributions.
Analysis of "omics" data is often a long and segmented process, encompassing multiple stages from initial collection to processing, quality control visualization. The cross-modal nature recent genomic analyses renders this process challenging both automate standardize; consequently, users resort manual interventions that compromise reliability reproducibility. This in turn can produce versions datasets across storage systems. As result, scientists lose significant time resources trying...
