[Progress of generation mechanisms of auditory steady-state response].

The scalp-recorded auditory steady-state response (ASSR) is a periodically evoked potential in response to the stimulation with the acoustical property in the same period. The ASSR can be readily induced in comparison with transient responses for specific conditions. The clinical utility of ASSR may be unjustified for the ambiguity of the genesis. With the advance of relevant research, it is considered that the main generation hypotheses of the ASSR are conceived to be pertinent with the linear superposition or neural entrainment mechanism. Based on current findings and our contributions in this field, we introduce recent progresses of the two mechanisms with comments, and suggest the benefit of the rapid stimulation technology in this regard.
