The Cognitive Auditory Evoked Potential (CAEP) - P300 has been used to measure and monitor neurophysiological modifications of the central auditory nervous system (Alonso & Schochat, 2009; Anderson, Baldridge & Stanford, 2011; Sassi, Matas, de Mendonça & de Andrade, 2011).
Given that P300 is an endogenous potential elicited by auditory discrimination when the subject consciously reacts to rare stimuli randomly presented between frequent stimuli (Musiek …show more content…
The N2 component is associated with perception, discrimination, recognition, and classification of an auditory stimulus and has multiple generators, among which is the supratemporal cortex (Musiek & Lee 2001). In this manner, P300 and N2 can be investigated in students with developmental dyslexia, once they present alterations in their phonological aptitudes (Alvarenga, Araújo, Ferraz & Crenitte, …show more content…
In relation to the use of CAEP as a tool to monitor the therapeutic evolution in dyslexic, Jucla, Nenert, Chaix e Demonet (2010) investigated the N170 and P300 components before and after intensives two-month training programs, one based on phonemic awareness and the other on visual and orthographic processing. The authors’ finds showed that training might modulate cortical activity in dyslexic children in a visual word recognition task and these results reflect the strong link between the reading skill improvements after
