Abstract:Purpose
Detecting sound‐related activity using functional MRI requires the auditory stimulus to be more salient than the intense background scanner acoustic noise. Various strategies can reduce the impact of scanner acoustic noise, including “sparse” temporal sampling with single/clustered acquisitions providing intervals without any background scanner acoustic noise, or active noise cancelation (ANC) during “continuous” temporal sampling, which generates an acoustic signal that adds destructively to the scann… Show more
