Abstract

BACKGROUND AND OBJECTIVES

The aim of the study was to investigate the influence of musical practice on brain plasticity. BDNF (brain-derived neurotrophic factor) is a neurotrophin involved in neuroplasticity and synaptic function.

MATERIALS AND METHODS

We recruited 48 healthy subjects of equal age and sex (21 musicians and 27 non-musicians). All subjects were administered the AQ (Autism-Spectrum Questionnaire) and plasma levels (PLs) of BDNF, oxytocin (OT), and vasopressin (VP) were measured in the blood sample of every participant.

RESULTS

The difference between BDNF PLs in the two groups was found to be statistically significant (t = - 2.214, p = 0.03). Furthermore, oxytocin (OT) PLs and musical practice were found to be independent positive predictors of BDNF PLs (p < 0.04). We also found a negative correlation between BDNF PLs and AD (attention to detail) sub-scale score of AQ throughout the whole sample. Assuming BDNF PLs to be a marker of synaptic plasticity, higher PLs could be associated with the activation of alternative neural pathways: a lower score in the "attention to detail" sub-scale could imply greater flexibility of higher cerebral functions among musicians. Further researches should be conducted to assess the rehabilitative usefulness of these findings among patients affected by psychiatric disorders.
