Bayesian workflow for the investigation of hierarchical classification models from tau-PET and structural MRI data across the Alzheimer's disease spectrum

Author(s): Belasso CJ; Cai Z; Bezgin G; Pascoal T; Stevenson J; Rahmouni N; Tissot C; Lussier F; Rosa-Neto P; Soucy JP; Rivaz H; Benali H; ...

Background: Alzheimer's disease (AD) diagnosis in its early stages remains difficult with current diagnostic approaches. Though tau neurofibrillary tangles (NFTs) generally follow the stereotyp ...

Lactate's behavioral switch in the brain: an in-silico model

Author(s): Soltanzadeh M; Blanchard S; Soucy JP; Benali H;

It is well known that glucose serves as the main energy substrate for the brain, and emerging evidence emphasizes its involvement in both physiological processes and disease (traumatic brain injury, memory, epilepsy, etc.). Furthermore, the usefulness of ma ...

Integrating machine learning and digital microfluidics for screening experimental conditions

Author(s): Ahmadi F; Simchi M; Perry JM; Frenette S; Benali H; Soucy JP; Massarweh G; Shih SCC;

Digital microfluidics (DMF) has the signatures of an ideal liquid handling platform - as shown through almost two decades of automated biological and chemical assays. However, in the current state of DMF, we are still limited by the number of parallel biolo ...

Hierarchical Bayesian modeling of the relationship between task-related hemodynamic responses and cortical excitability

Author(s): Cai Z; Pellegrino G; Lina JM; Benali H; Grova C;

Investigating the relationship between task-related hemodynamic responses and cortical excitability is challenging because it requires simultaneous measurement of hemodynamic responses while applying noninvasive brain stimulation. Moreover, cortical excitab ...

Voice characteristics from isolated rapid eye movement sleep behavior disorder to early Parkinson's disease

Author(s): Jeancolas L; Mangone G; Petrovska-Delacrétaz D; Benali H; Benkelfat BE; Arnulf I; Corvol JC; Vidailhet M; Lehéricy S; ...

Background: Speech disorders are amongst the first symptoms to appear in Parkinson's disease (PD). Objectives: We aimed to characterize PD voice signature from the prodromal stage (isolated ra ...

An altered balance of integrated and segregated brain activity is a marker of cognitive deficits following sleep deprivation

Author(s): Cross NE; Pomares FB; Nguyen A; Perrault AA; Jegou A; Uji M; Lee K; Razavipour F; Ali OBK; Aydin U; Benali H; Grova C; Dang-Vu TT; ...

Sleep deprivation (SD) leads to impairments in cognitive function. Here, we tested the hypothesis that cognitive changes in the sleep-deprived brain can be explained by information processing withi ...

Multimodal 3D ultrasound and CT in image-guided spinal surgery: public database and new registration algorithms

Author(s): Masoumi N; Belasso CJ; Ahmad MO; Benali H; Xiao Y; Rivaz H;

Purpose: Accurate multimodal registration of intraoperative ultrasound (US) and preoperative computed tomography (CT) is a challenging problem. Construction of public datasets of US and CT images can accelerate the development of such image registration tec ...

X-Vectors: New Quantitative Biomarkers for Early Parkinson's Disease Detection From Speech

Author(s): Jeancolas L; Petrovska-Delacrétaz D; Mangone G; Benkelfat BE; Corvol JC; Vidailhet M; Lehéricy S; Benali H; ...

Many articles have used voice analysis to detect Parkinson's disease (PD), but few have focused on the early stages of the disease and the gender effect. In this article, we have adapted the la ...
