Power Spectral Density (PSD) across conditions. The spectral power of one typical subject in each condition (ST = Single-Task walking; DT1 = Dual-Task walking while conversing; DT2 = Dual-Task walking while texting with a smartphone) and for each frequency band of interest (θ, α and β). Values are colour-coded and expressed in dB. Subject P.S. gave written informed consent for the publication of her data
