Longitudinal Dynamic fMRI Analysis of Music vs Singing Perception in Preterm Infants

2024

Abstract

Motivation: Instrumental music and singing differ due to the vocal component of the sung melody and present distinct neural processing pathways, though its developmental origins remain unclear. Goal(s): This study explores the early development of music vs singing brain processing. Approach: Dynamic PPI-CAPs approach was applied to longitudinal fMRI data of preterm infants at 33- and 40-weeks gestational age. Results: Singing elicited a stronger activation of salience and language-related networks, while music elicited limbic networks. Default-mode network and right temporal gyrus were elicited for both stimuli longitudinally. Visual network is also involved for both stimuli but only at term-equivalent age. Impact: This study explores the longitudinal early development of neural processing networks in the context of instrumental and vocal music stimuli and shows that preterm infants already present a specialized processing for these different stimuli.

Music psychology

Music psychology, or the psychology of music, may be regarded as a branch of both psychology and musicology. It aims to explain and understand musical behaviour and experience, including the processes through which music is perceived, created, responded to, and incorporated into everyday life. Modern music psychology is primarily empirical; its knowledge tends to advance on the basis of interpretations of data collected by systematic observation of and interaction with human participants.

Artificial neural network

Artificial neural networks (ANNs, also shortened to neural networks (NNs) or neural nets) are a branch of machine learning models that are built using principles of neuronal organization discovered by connectionism in the biological neural networks constituting animal brains. An ANN is based on a collection of connected units or nodes called artificial neurons, which loosely model the neurons in a biological brain. Each connection, like the synapses in a biological brain, can transmit a signal to other neurons.

Singing

Singing is the act of creating musical sounds with the voice. A person whose profession is singing is called a singer, artist or vocalist (in jazz and/or popular music). Singers perform music (arias, recitatives, songs, etc.) that can be sung with or without accompaniment by musical instruments. Singing is often done in an ensemble of musicians, such as a choir. Singers may perform as soloists or accompanied by anything from a single instrument (as in art songs or some jazz styles) up to a symphony orchestra or big band.
