Experience-Induced Plasticity in the Attention System in Healthy Adults Practicing Musical or Non-Musical Cognitivo-Motor Activity

The primary objective of this study was to investigate structural brain aging within the attentional system of singers and instrumentalists. Specifically, we examined cortical aging across three groups: amateur singers, amateur instrumentalists, and non-musician active controls. Data were collected from 109 healthy adults, divided as follows: 34 amateur singers (mean age = 61.62 ± 16.19 years; age range = 23–88; 65% female), 38 amateur instrumentalists (mean age = 52.47 ± 18.82 years; age range = 20–88; 32% female), and 37 controls (mean age = 55.57 ± 18.97 years; age range = 20–87; 49% female). We are sharing the aggregated dataset used for group-level statistical analyses, enabling others to replicate our findings or explore new analyses on cortical thickness data.
