A new indwelling urethral catheter (amSafeX) to verify the position of its balloon within the bladder during inflation

Urology Video Journal
Introduction: Inserting a Foley catheter for urethral catheterization can lead to numerous iatrogenic injuries in patients, as it is difficult to ensure that the balloon is in the bladder during inflation.

The Neural Correlates of Consciousness and Attention: Two Sister Processes of the Brain

Frontiers in Neuroscience, 2019
During the last three decades our understanding of the brain processes underlying consciousness and attention has significantly improved, mainly because of the advances in functional neuroimaging techniques.

Multimodal contrastive learning on rs-fMRI to quantify whole-brain network recovery after hypothalamic hamartoma surgery

BioMedical Engineering OnLine
Introduction Epilepsy due to hypothalamic hamartoma (HH) is associated with epileptic encephalopathy and often requires surgical intervention, as medications are ineffective at reducing the seizures. However, the first step of disentangling the impact of

The Brain in (Willed) Action: A Meta-Analytical Comparison of Imaging Studies on Motor Intentionality and Sense of Agency

Frontiers in Psychology, 2019
Voluntary actions can be fractionated in different phenomena: from the emergence of intentions and the ensuing motor plans and actions, to the anticipation and monitoring of their outcomes, to the appreciation of their congruency with intentions and to ...

Extracting Weight of Evidence from p-Value via Bayesian Approach to Activation Likelihood Estimation Meta-Analysis

Brain Sciences
Background: p-values are ubiquitous in scientific research, yet they fundamentally fail to quantify the strength of evidence for or against competing hypotheses. This limitation is particularly problematic in neuroimaging meta-analyses, where researchers

Neural correlates of meditation: a review of structural and functional MRI studies

Frontiers in Bioscience-Scholar, 2020
Here, we review the neurophysiological and neuroimaging changes that mediation induces in structural and functional MRI. The available evidence from structural studies suggests that mediation impacts neuronal plasticity and the functional MRI suggest ...

The PRESTO technique for fMRI [PDF]

NeuroImage, 2012
In the early days of BOLD fMRI, the acquisition of T(2)(*) weighted data was greatly facilitated by rapid scan techniques such as EPI. The latter, however, was only available on a few MRI systems that were equipped with specialized hardware that allowed rapid switching of the imaging gradients.

SmartPhantom — an fMRI simulator [PDF]

Magnetic Resonance Imaging, 2006
Many informatics tools have emerged to process the voluminous and complex data generated by functional magnetic resonance imaging (fMRI). The interpretation of fMRI exams is largely determined by these tools. However, their performance is hard to evaluate because there is no independent means of calibration.
