Our sense of rhythm relies on orchestrated activity of several cerebral and cerebellar
structures. Although functional connectivity studies have advanced our understanding
of rhythm perception, this phenomenon has not been sufficiently studied as a function of
musical training and beyond the General Linear Model (GLM) approach. Here, we studied
pulse clarity processing during naturalistic music listening using a data-driven approach
(independent component analysis; ICA). Participants’ (18 musicians and 18 controls)
functional magnetic resonance imaging (fMRI) responses were acquired while listening
to music. A targeted region of interest (ROI) related to pulse clarity processing was
defined, comprising auditory, somatomotor, basal ganglia, and cerebellar areas. The ICA
decomposition was performed under different model orders, i.e., under a varying number
of assumed independent sources, to avoid relying on prior model order assumptions. The
components best predicted by a measure of the pulse clarity of the music, extracted
computationally from the musical stimulus, were identified. Their corresponding spatial
maps uncovered a network of auditory (perception) and motor (action) areas in an
excitatory-inhibitory relationship at lower model orders, while mainly constrained to the
auditory areas at higher model orders. Results revealed (a) a strengthened functional
integration of action-perception networks associated with pulse clarity perception hidden
from GLM analyses, and (b) group differences between musicians and non-musicians in
pulse clarity processing, suggesting lifelong musical training as an important factor that
may influence beat processing.

Functional connectivity of major depression disorder using ongoing EEG during music perception
Liu, Wenya; Zhang, Chi; Wang, Xiaoyu; Xu, Jing; Chang, Yi; Ristaniemi, Tapani; Cong, Fengyu (Elsevier BV, 2020)Objective The functional connectivity (FC) of major depression disorder (MDD) has not been well studied under naturalistic and continuous stimuli conditions. In this study, we investigated the frequency-specific FC of MDD ... -
Snowball ICA : A Model Order Free Independent Component Analysis Strategy for Functional Magnetic Resonance Imaging Data
Hu, Guoqiang; Waters, Abigail B.; Aslan, Serdar; Frederick, Blaise; Cong, Fengyu; Nickerson, Lisa D. (Frontiers Media, 2020)In independent component analysis (ICA), the selection of model order (i.e., number of components to be extracted) has crucial effects on functional magnetic resonance imaging (fMRI) brain network analysis. Model order ... -
