“…These ERP findings suggested on reduced neural performance in processing early onset of auditory stimulus, auditory perception and auditory attention, respectively to N100, P200 and P300 ERP components. 22 Similar findings of electrophysiological ERP studies can be seen in recent studies such as Papagiannoupoulou and Lagopoulos (2017), Halliday et al, (2014), Maciejewska et al, (2013), that being simplified in Table 1 (Table 1). 23 i.…”

Dyslexia is a reading disorder defined as the consequences of sensory impairment which can be quite tricky in diagnosis, as many symptoms of dyslexia tend to overlap with learning disabilities such as specific language Impairment (SLI), dysgraphia, dyscalculia, and a few others. However, as research keeps on progressing, a consensus has been made suggesting that dyslexia is commonly attributed to the impairment of auditory and visual perception. This review paper intends to discuss the detailed progression of research focusing on auditory and visual perception among dyslexics.

“…Previous ERP studies on these individuals have shown mixed results. Though few authors have observed no latency difference in auditory late latency response (ALLR) using click stimulus except for P1 ( Purdy et al ., 2002), other studies suggest that individuals with LDs often have prolonged latency when compared with controls in all ALLR components ( Frizzo, 2015; Kumar & Gupta, 2014). The delay may be because of altered cortical functions ( Pinkerton et al ., 1989), short attention span ( Picton et al ., 1978), or deficits in auditory cortical information synchronization associated to auditory attention factors ( Leppänen & Lyytinen, 1997).…”

Cortical auditory evoked potentials and hemispheric specialization of speech in individuals with learning disability and healthy controls: A preliminary study

Background: Dichotic listening (DL) technique is a behavioral non-invasive tool which is used in studying hemispheric lateralization. Previous studies using behavioral DL have hypothesized that individuals with learning disabilities (LD) exhibit a lack of cortical specialization for processing speech stimulus. However, there is no event related potential (ERP) evidence, hence the main objective of the study is to explore hemispheric asymmetry using cortical auditory evoked potential (CAEPs) in normal hearing adults and also to compare the same in children with LD and healthy controls. Methods: CAEPs were recorded in 16 normal hearing young adults, eight right-handed children with LD and their age matched controls. Two stop constants (/Pa/ – voiceless, bilabial, stop: /Ta/ - voiceless, alveolar, stop) were chosen for this experiment and presented in each ear and dichotically in two different orders (/pa-ta/, /ta-pa/). ERPs were processed using a standard pipeline, and electrodes readings over the left and right hemispheres were averaged to create left and right regions of interest (ROI). The CAEPs were analyzed for mean amplitude and peak latency of P1-N1-P2 components. Results: The current study results suggest no statistically significant difference between the two stimulus in monaural condition and absence of order effect in dichotic condition. In healthy controls the CAEP latencies were shorter over the left hemisphere in both monaural and dichotic conditions in adults and control children. However, it was very evident that such a difference was lacking in children with LD. Conclusions: Hemispheric asymmetry can be detected using CAEPs for speech stimulus. The measures are consistent and void of stimulus or order effect. Taken together, the findings of current study, both monaural and dichotic condition illustrates the hemispheric differences in processing speech stimuli in normal hearers. Absence of latency differences between hemispheres in children with LD indicate a lack of hemispheric asymmetry.

“…Maturation of CNS depends primarily on the myelination of nerve fibers, which lead the signal to the corresponding cortical centres which generate the cortical evoked potentials (19). Moreover, early and developmental evaluation of auditory ERPs is a promising approach that may find application in monitoring the dynamics of some developmental disorders and diseases such as dyslexia, autism (3,8,14). Based on recent findings which were reviewed in this article, we suggest that CAEPs should become an integral part of clinical practice to evaluate children's auditory development.…”

“…central nervous system (CNS). Improper engagement and functioning of the higher auditory areas can lead to disorders such as the auditory processing deficit, dyslexia, or learning disability (3,8). Detection of the brainstem, early, and later evoked potentials, also called event-related potentials (ERPs), allow us to examine the subsequent stages of auditory stimulus processing.…”

This review article introduces the basic principles of infants’ neurophysiology, while summarizing the core knowledge of the anatomical structure of the auditory pathway, and presents previous findings on newborns’ neural speech processing and suggests their possible applications for clinical practice. In order to tap into the functioning of the auditory pathway in newborns, recent approaches have employed electrophysiological techniques that measure electrical activity of the brain. The neural processing of an incoming auditory stimulus is objectively reflected by means of auditory event-related potentials. The newborn’s nervous system processes the incoming sound, and the associated electrical activity of the brain is measured and extracted as components characterized by amplitude, latency, and polarity. Based on the parameters of event-related potentials, it is possible to assess the maturity of a child’s brain, or to identify a pathology that needs to be treated or mitigated. For instance, in children with a cochlear implant, auditory event-related potentials are employed to evaluate an outcome of the implantation procedure and to monitor the development of hearing. Event-related potentials turn out to be an irreplaceable part of neurodevelopmental care for high-risk children e.g., preterm babies, children with learning disabilities, autism and many other risk factors.
