2007 NeuroImage  
In human auditory cortex, the temporal blood oxygen level-dependent (BOLD) response to auditory inputs, as measured by functional magnetic resonance imaging (f MRI), consists of at least two independent  ...  components: an initial transient and a subsequent sustained signal, which, on a different time scale, are consistent with electrophysiological human and animal response patterns.  ...  There are, however, only a few f MRI studies, that have segmented the blood oxygenation level-dependent (BOLD) signal in the time domain, although in auditory cortex the BOLD signal evoked by prolonged  ...

Right Hemispheric Laterality of Human 40 Hz Auditory Steady-state Responses

B. Ross, A.T. Herdman, C. Pantev
2005 Cerebral Cortex  
Thus, laterality of sustained response components (SF and ASSR) was distinct from that of transient responses. ASSR and SF are sensitive to stimulus periodicity.  ...  In summary, the results of the present studies demonstrate that asymmetric organization in the cerebral auditory cortex is already established on the level of sensory processing.  ...  ASSR laterality toward the RH might facilitate RH asymmetry for pitch processing based on the temporal periodicity of sound.  ...
