Article
Full-text available
Significant progress has been made with regard to the quantitative integration of geophysical and hydrological data at the local scale for the purpose of improving predictions of groundwater flow and solute transport. However, extending corresponding approaches to the regional scale still represents one of the major challenges in the domain of hydr...
Article
Full-text available
We critically examine the performance of sequential geostatistical resampling (SGR) as a model proposal mechanism for Bayesian Markov-chain-Monte-Carlo (MCMC) solutions to near-surface geophysical inverse problems. Focusing on a series of simple yet realistic synthetic crosshole georadar tomographic examples characterized by different numbers of da...
Article
Full-text available
The conflict monitoring model predicting higher anterior cingulate cortex (ACC) neuronal activity on incongruent trials has been recently challenged by a model predicting longer neuronal activity in incongruent trials characterized by longer RTs. To clarify this issue, brain dynamics were explored through event-related-potential (ERP) recordings du...
Article
Full-text available
Knowledge of the spatial distribution of hydraulic conductivity (K) within an aquifer is critical for reliable predictions of solute transport and the development of effective groundwater management and/or remediation strategies. While core analyses and hydraulic logging can provide highly detailed information, such information is inherently locali...
Article
Full-text available
Inhibitory control (IC), the ability to suppress inappropriate actions, can be improved by regularly facing complex and dynamic situations requiring flexible behaviors, such as in the context of intensive sport practice. However, researchers have not clearly determined whether and how this improvement in IC transfers to ecological and nonecological...
Article
Full-text available
Cardiorespiratory fitness is thought to be positively related to sustained attention. However, the underlying mechanisms of this relationship have yet to be fully elucidated. The objective of this study was to i) explore the relationship between cardiorespiratory fitness and sustained attention in 72 young adults (18–37 years old) and ii) provide i...

Human learning is an active and complex process. However, the brain mechanisms underlying human skill learning and the effect of learning on the communication between brain regions, at different frequency bands, are still largely unknown. Here, we tracked changes in large-scale electrophysiological networks over a 6-week training period during whic...
Article
Full-text available
During normal aging resting-state brain activity changes and working memory performance declines as compared to young adulthood. Interestingly, previous studies reported that different electroencephalographic (EEG) measures of resting-state brain activity may correlate with working memory performance at different ages. Here, we recorded resting-sta...
Article
Full-text available
Alterations of resting-state EEG microstates have been associated with various neurological disorders and behavioral states. Interestingly, age-related differences in EEG microstate organization have also been reported, and it has been suggested that resting-state EEG activity may predict cognitive capacities in healthy individuals across the lifes...
Article
Full-text available
Williams (WS) and Down (DS) syndromes are neurodevelopmental disorders with distinct genetic origins and different spatial memory profiles. In real-world spatial memory tasks, where spatial information derived from all sensory modalities is available, individuals with DS demonstrate low-resolution spatial learning capacities consistent with their m...
Article
Full-text available
Motor inhibitory control (IC), the ability to suppress unwanted actions, has been previously shown to rely on domain-general IC processes that are involved in a wide range of IC tasks. Nevertheless, the existence of effector-specific regions and activation patterns that would differentiate manual vs. oculomotor response inhibition remains unknown....
Article
Interindividual variations in the ability to perform visuospatial mental transformations have been investigated extensively, in particular through mental rotation tasks. However, the impact of early visual processes on performance has been largely ignored. To clarify this issue, we explored the time‐course of early visual processing (from 0 to 450...

We investigated changes in resting-sate EEG signal over learning periods. In particular, we recorded resting periods falling between task trials in order to systematically investigate changes in resting-state EEG signal over a period of learning. We respectively analyzed frequency and time domain in order to evaluate changes in power spectrum and p...
Conference Paper
Anxiety is associated with disruptions of the frontal-amygdala circuitry that induce biases in normal processing of sensory information. In particular, anxiety can increase attention towards potentially threatening stimuli, but also entrains broader attentional changes regardless of threat. Cortical origin of controlled attention is thought to be s...

Full-text available
The geostatistical integration of geophysical and hydrological data has significant potential for adequately characterizing heterogeneous aquifers. Although progress has been made in this regard, the proposed methods were so far mostly limited to the local scale. Recently, Ruggeri et al. (2013) proposed a two-step Bayesian sequential simulation (BS...

Conference Paper
Full-text available
In soil science, the hysteretic nature of the water retention curve plays an important role in describing a soil’s propensity to retain water and conduct fluid flow. However, hysteresis effects remain difficult to study and to quantify. Geophysical methods provide suitable and non-invasive tools that could be used for this purpose. For example, the...
Article
Deterministic inverse methods offer a robust and proven means of obtaining estimates of spatially distributed subsurface parameters from geophysical data. However, assessing the corresponding uncertainty in the parameters for the general non-linear inverse problem remains an ongoing research challenge. Recently, much work in geophysics and hydrolog...
Article
Significant progress has been made with regard to the quantitative integration of geophysical and hydrological data at the local scale. However, extending corresponding approaches to the regional scale still represents a major challenge, yet is critically important for the development of groundwater flow and contaminant transport models. To address...
Article
Significant progress has been made with regard to the quantitative integration of geophysical and hydrological data at the local scale. However, extending the corresponding approaches to the regional scale represents a major, and as-of-yet largely unresolved, challenge. To address this problem, we have developed a downscaling methodology based on a...
Conference Paper
In Earth sciences, it is common to image a target property using indirect low-resolution geophysical data. Downscaling low-resolution indirect data to the appropriate target resolution is a major issue in imaging. In this paper, we use a wavelet-based methodology to downscale the low-resolution geophysical images to high-resolution geological model...
