“…The N100 ERP component reflects the auditory perception. Higher amplitude of the N100 component reflected the poor developmental perception of the auditory system 54 . One study found a higher amplitude of the N100 component in alexithymic subjects, and they interpreted that they have impairment of auditory perception 55 .…”

Objectives: We investigated the auditory cognitive and behavioral functions during 2nd and 3rd trimesters of pregnancy using event-related potentials (ERPs) and different neuropsychology tests, respectively. Methods: The ERPs were studied by using a 128-sensor net, and PAS/COWA, WCST, ZCT, RAVLTIM/RAVLTDR/RAVLTTS, and BDI were tested for neuropsychology assessment. Total 39 subjects were recruited for control group (G1, n=15, non-pregnant), 2nd trimester group (G2, n=12, 13-26 weeks gestation), and 3rd trimester group (G3, n=12, 26- 40 weeks gestation). Auditory oddball paradigm was used during ERP study. Subjects silently counted only the target stimuli with attention by ignoring standard stimuli. Value of the mean differences of the target and standard stimuli were measured across groups in 10-20 electrode systems. Results: The P50, N100, and P300 ERP components were analyzed. The G3 (at F7 and C3) and G2 (at T4) groups evoked the highest significant amplitudes in P50, and G3 (at Cz and Pz) and G1 (at F8 and T4) evoked the highest significant amplitudes of N100 with significantly prolonged latencies at Cz and O1 (in G1) and F8 (in G2). However, significantly higher amplitudes of P300 were found at Fz (in G3) and FP1 (G2) (G2>G3). On the other hand, neuropsychology tests revealed that G2 possessed the highest significant score in WCST and G1 in ZCT. The G3 performed poorly in all tests. Conclusion: We concluded that pregnant groups performed better in auditory (attention/memory) and executive function assessment. Moreover, the 2nd trimester group has better auditory cognitive function compared to the 3rd trimester group due to the effect of hormonal changes during pregnancy, which might be a positive influence during the pregnancy period.

“…The longest significant latencies were found in the control group in two areas (Cz and O1), and one area (F8) reflected significant longer latency in the 2 nd trimester group (Table 1). Taking the points from the previous interpretations 54,55 , we can say that the 3 rd trimester pregnant group has poor auditory perception.…”

“…Newborns' MMR, similarly to adults' MMN, reflects rather fine phonetic discrimination abilities, such as the ability to distinguish sounds coming from different sources, or the ability to detect both a change in speaker voice and in speech sound quality (9). This observation in healthy newborns indicates that the neonatal brain has a fully developed discriminatory capacity for sound stimuli (17), although its CNS structures are not yet fully mature (19)(20)(21). Newborns' MMR also indexes the ability to differentiate variations in auditory stimuli that are important for speech and language development (17).…”

“…ERP amplitude, on the contrary, seems to correlate with the number of neural structures involved in the response (number of synapses). Early developmental changes in the amplitude of the auditory ERP thus seem to depend mainly on gestational age, and less so on the amount of (extrauterine) auditory exposure (2,4,20,21).…”

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.

“…Previous studies of comatose patients’ reactivity showed that unconscious patients demonstrated higher responses to emotionally charged stimuli than neutral stimuli [ 1 - 3 ]. Some researchers found that unconscious patients or sleeping subjects responded to emotional stimuli such as their names or alarm sounds, whereas comparable neutral stimuli did not elicit any significant response [ 2 , 4 ].…”

Objective: The acoustic stimulation in consciousness patients may improve the diagnosis assessment and the effectiveness of rehabilitation procedures. We aimed to investigate the event-related potential (ERP) response to emotional auditory stimuli in comatose patients. Methods: We measured the nonlinear and linear electroencephalogram (EEG) features, prepared the acoustic analysis of stimuli parameters, and assessed the subjective emotional rates of stimuli characteristics. Results: Patients with better outcomes had recognizable ERP responses and significant changes of the nonlinear EEG features to emotional sounds, unlike patients with worse outcomes. The response of comatose patients was attributed to acoustical features of emotional sounds, whereas the EEG response of healthy subjects was associated with their subjective feelings. The comatose patients demonstrated the variable EEG activity for neutral and emotional sounds. Conclusion: Thus, the EEG reactivity followed the better outcome of comatose patients to emotional stimuli. The study assumed the substantial differences of emotional stimuli perception in the healthy and unconscious brain.
