Abstract

The recording of auditory steady state response (ASSR) has been expanded recently in audiological clinical practice, as a result of numerous advantages of this technique. Mainly it is generated by specific frequency acoustic stimulus and also for the possibility of automatic detection of response by applying statistic indicators. However the neural generators of multiple frequency ASSR has not been widely studied, and there is not clear consensus in the review reports about precise localization of neural generators of ASSR. The discussion of nature of ASSR generators is cause of severe controversy in scientific community. Many authors have been postulated that ASSR is generated as superposition of transient responses. Meanwhile others proposed that it is reflect the specific intrinsic neural rhythm activation and as a result is generated by specific neural sources. The present bibliographic review has been designed with the aim of critical analysis of studies that have been evaluated the brain sources of multiple frequency ASSR to define if there is or not any consensus about identification and characterization of ASSR generators. Also this review address to identification of feasibility to develop a new research for ASSR Sources localization applying novel inverse solution methods recently introduced in neurosciences.
