Figure 1From: Bottom-up driven involuntary attention modulates auditory signal in noise processingStimuli were presented in blocks of constant or random tone sequences. All of those tone sequences were either presented in silence or in noise. The length of the tone stimuli was 0.7 s, the ISI was randomized between 1.3 and 2.3 s. Exemplary sound files are attached to Additional file 1.Back to article page
