Are advanced methods necessary to improve infant fNIRS data analysis? An assessment of baseline-corrected averaging, general linear model (GLM) and multivariate pattern analysis (MVPA) based approaches [PDF]

open access: yesNeuroImage, 2023
In the last decade, fNIRS has provided a non-invasive method to investigate neural activation in developmental populations. Despite its increasing use in developmental cognitive neuroscience, there is little consistency or consensus on how to pre-process and analyse infant fNIRS data.

Statistical Analysis of fMRI Time-Series: A Critical Review of the GLM Approach [PDF]

open access: yesFrontiers in Human Neuroscience, 2011
Functional Magnetic Resonance Imaging (fMRI) is one of the most widely used tools to study the neural underpinnings of human cognition. Standard analysis of fMRI data relies on a General Linear Model (GLM) approach to separate stimulus induced signals ...

Second derivative General Linear Method in Nordsieck form

open access: yesJournal of Numerical Analysis and Approximation Theory, 2019
This paper considers the construction of second derivative general linear methods (SD-GLM) from hybrid LMM and their transformation to Nordsieck GLM. How the Runge-Kutta starters for the methods can be derived are given.

Improved cerebrovascular reactivity mapping using coherence weighted general linear model in the frequency domain

open access: yesNeuroImage, 2023
Cerebrovascular reactivity (CVR) is a prognostic indicator of cerebrovascular health. Estimating CVR from endogenous end-tidal carbon dioxide (CO2) fluctuation and MRI signal recorded under resting state can be difficult due to the poor signal-to-noise ...

Numerical Treatment of Hybrid Fuzzy Differential Equations Subject to Trapezoidal and Triangular Fuzzy Initial Conditions Using Picard’s and the General Linear Method

open access: yesComputation, 2022
We study hybrid fuzzy differential equations (HFDEs) under the Hukuhara derivative numerically using Picard’s and the general linear method (GLM). We use trapezoidal and triangular fuzzy numbers as the initial conditions. To demonstrate the efficiency of

Inter-subject correlation in fMRI: method validation against stimulus-model based analysis. [PDF]

open access: yesPLoS ONE, 2012
Within functional magnetic resonance imaging (fMRI), the use of the traditional general linear model (GLM) based analysis methods is often restricted to strictly controlled research setups requiring a parametric activation model.

Composite symmetric general linear methods (COSY-GLMs) for the long-time integration of reversible Hamiltonian systems [PDF]

open access: yesBIT Numerical Mathematics, 2018
The author constructs a class of efficient numerical integration methods for the long time integration of reversible Hamiltonian systems. The approach is based on a composition of one-step methods, yielding some symmetric general linear methods, and the primary goal is to obtain high order methods.
