Music stimulation of the auditory system has become a key interdisciplinary field of research involving neuroscience, molecular biology, psychology and cognitive science. Recent studies indicate that music is not only a cultural and emotional experience, but also a biological stimulus which can regulate neural activity, synaptic plasticity, and gene expression involved in brain function. This paper provides an overview of the connection between auditory stimuli (music) and its impact on neural plasticity genes, neurotransmission genes, memory genes and emotional regulation genes. Human and animal studies have shown that music exposure can affect the expression of immediate early genes (IEGs) like FOS, ARC and ZENK, and of neurotrophic factors like Brain-Derived Neurotrophic Factor (BDNF). These molecular changes lead to increased neural connectivity, better cognitive function, reduced stress and neuroprotection. Listening and musical training have been demonstrated to modify the transcriptomic pathway related to dopamine signaling, synaptic transmission and cortical plasticity. Further, CREB mediated signaling of prenatal and early developmental auditory stimulation to the hippocampus and to memory related pathways. Music is also shown to involve large-scale neural networks in functional imaging studies, including those of the auditory cortex, limbic system, hippocampus, and prefrontal cortex. This paper summarizes the available literature on music-induced neuroplasticity at the molecular level and examines the potential of music in therapeutic interventions for neurological and psychiatric diseases. The results suggest that music is a biologically impactful tool that can affect neural regulation of genes and functional brain adaption. In the future, combining genomics, neuroimaging, and auditory neuroscience could further elucidate the therapeutic potential of music-based interventions in improving cognitive health and neural recovery.
