Subject: Literature on N1P2 complex (ACC) From: akartik1 narayanan <akartik1(at)YAHOO.COM> Date: Sun, 30 Jan 2005 07:20:38 -0800 Comments:DomainKeys? See http://antispam.yahoo.com/domainkeys--0-1109964300-1107098438=:90299 Content-Type: text/plain; charset=us-ascii Dear list members, I have undertaken my dissertation in Acoustic change complex (ACC). For a brief introduction: -- it is a N1P2 complex elicited by using a stimuli which has a cange in spectral envelope over a period of time or which fluctuates in its periodicity (amplitude). I have tried recording ACC for two stimuli, viz.|sh| and |shu| [stimulus duration: 250 msecs, instrument: IHS evoked potential system]. Althoughg the literature by Ostroff, Martin, Boothroyd (1998, 1999, & 2000), is indicative of a robust difference in overall N1P2 amplitude, but the classicasl response is not being observed. What could be the possible reason for this discrepancy. I would appreciate valuable suggestions from one & all. Please do also suggest if there has been any kind of previous research (literature available) undertaken on any of the relevant aspects of this research venture N.Kartik, E-mail: akartik1(at)yahoo.com, Postgraduate student (Audiology), All India Institute of Speech and hearing, Naimisham Campus, manasagangothri, Mysore - 570006, Karnataka, India.
