Dual tasks (DTs) combining walking with a cognitive task can cause various levels of cognitive-motor interference, depending on which brain resources are recruited in each case. However, the activation and functional connectivity underlying interferences remain to be elucidated. Therefore, this study investigated neural correlation during different DT conditions 40 healthy young adults (mean age: 27.53 years, 28 women). The DTs included subtraction or N-Back tasks.
