Localization of the hand motor area by arterial spin labeling and blood oxygen level-dependent functional magnetic resonance imaging.

abstract：:Auditory steady-state responses (ASSRs) are evoked brain responses to modulated or repetitive acoustic stimuli. Investigating the underlying neural generators of ASSRs is important to gain in-depth insight into the mechanisms of auditory temporal processing. The aim of this study is to reconstruct an extensive range o...
