Re: Does noise mask exist in rat primary auditory cortex?

Hi Wichian,
I guess I did not make it clear.  I mean the percept of a completetone even partly covered by background noise, not oddball situation. It is similar to fill-in phenomena in visual perception in a way.  Youmay check the following paper, in which an example was shown.  Thanksfor your response.
