Maturation of CAEP in infants and children: A review

Auditory sensory deficits in developmental dyslexia: A longitudinal ERP study

“…Furthermore, these group differences were observed in both test phases of the study. A common finding is that P1 latency in children decreases with age and increases with faster repetition rates (Gilley et al, 2005;Sussman et al, 2008;Wunderlich and Cone-Wesson, 2006). As Gilley et al (2005) point out, developmental changes in myelination, synaptic refinement and cortical fibre density underlie changes in P1 (and other components') latency and amplitude.…”

Enhancement of brain event-related potentials to speech sounds is associated with compensated reading skills in dyslexic children with familial risk for dyslexia

“…Infants reach the adult latency range of 140-170 ms by the age of 15 months (Barnet, Ohlrich, Weiss, & Shanks, 1975;. Both amplitude increases and decreases with age have been reported (Wunderlich & Cone-Wesson, 2006). Altogether, the reported developmental changes concerning the P2 response are relatively small.…”

“…It peaks at around 200-250 ms in young infants (Wunderlich & Cone-Wesson, 2006). Infants reach the adult latency range of 140-170 ms by the age of 15 months (Barnet, Ohlrich, Weiss, & Shanks, 1975;.…”

“…The P1 response originates from the secondary auditory cortex, more specifically from the lateral part of the Heschl's gyrus (LiegeoisChauvel, Musolino, Badier, Marquis, & Chauvel, 1994). N1 peaks in children at 100-150 ms with fronto-central distribution, with the latency decreasing with age (Bruneau & Gomot, 1998;eponien et al, 2002;Cunningham et al, 2000;Sharma, Kraus, McGee, & Nicol, 1997;Tonnquist-Uhlén, Borg, & Spens, 1995;Wunderlich & Cone-Wesson, 2006). N1 has been reliably detected in childhood with long ISIs (> 1 s) only, showing increase with age (e.g., eponien et al, 2002;Gilley, Sharma, Dorman, & Martin, 2005).…”

“…N2 peaks at latency around 300-550 ms in early infancy, and it declines to around 220-245 ms until preschool age (Wunderlich & Cone-Wesson, 2006). Amplitude also gradually decreases in school age, stabilizing by early adulthood (Cunningham et al, 2000;Tonnquist-Uhlén, 1996;Wunderlich & ConeWesson, 2006).…”
