“…The early responses can document how well sensory information is being received by the nervous system and how efficiently this information is being transmitted to the cerbral cortex. Extensive developmental normative studies are available for the early responses, which are used clinically in pediatric neurology (e.g., Picton, Taylor, & Durieux-Smith, 2005;Taylor, 1993a). The later ERPs have not been studied as extensively in terms of normative data, and are more variable from subject to subject.…”

The complex development of the human brain during infancy can only be understood by convergent structural, functional, and behavioral measurements. The evaluation of event-related potentials (ERPs) is the most effective current way to look at infant brain function. ERP paradigms can be used to examine the simple transmission of sensory information to the cortex and the discrimination of this information within the cortex. The main developmental changes involve localization of function as the brain becomes tuned to the experienced world (related to synaptic pruning) and a speeding up of transmission as pathways become efficient (related to myelination). ERPs that occur in relation to different temporal aspects of a stimulus (onset-responses, offset-responses, sustained potentials and steady-state responses) and ERPs recorded at different stimulus rates may help track perceptual development from a temporal perspective. Particularly important in human development are the ERP changes that occur in the processing of speech sounds and human faces. At present, ERP studies can show differences between groups of subjects that can demonstrate developmental disorders or elucidate mechanisms of development. However, because of their variability, ERPs are less helpful in determining whether an individual infant is developing abnormally. Where possible, ERP measurements should be used in conjunction with behavioral tests so as to relate performance to mechanism, and with anatomical brain measurements to relate mechanism to structure.

“…The sensori motor region witnesses the earliest myelogenesis [ 16 ]. Waves I, II and V of auditory brainstem responses are readily discernible at birth [ 17 ], while the inter-peak intervals II–III and IV–V continue to shorten during the first 2 years of life [ 18 ]. These intervals reflect trans-synaptic transmission.…”

Background: Otitis media (OM) leads to significant reduction in the hearing sensitivity. The reduced auditory input, if in the early years of life when the auditory neural system is still maturing, may adversely influence the structural as well as functional development of the system. Past research has reported abnormalities in both the structure and function of brainstem nuclei following auditory deprivation, but, it has not necessarily focused on children who had OM in their first year of life. It can also be said that if auditory processing is affected at the brainstem level because of early onset OM (reduced auditory input in the crucial periods of neural development), then, it may be said that auditory processing is also affected at the cortical level because it receives distorted input from the brainstem. Therefore, the purpose of this study was to document the effects of early onset OM on auditory processing, if any, at the brainstem as well as at cortical levels. A related purpose of the study was to investigate the persistence of the effects of early onset OM, if any, on auditory processing.

“…Place specificity can be improved by presenting masking noise alongside test stimuli (Burkard et al, 2007;Hood, 1998;T. Picton, Ouellette, Hamel, & Durieux-Smith, 1979;Purdy, Houghton, Keith, & Greville, 1989;Stapells, Gravel, & Martin, 1995).…”

PurposeThis study investigates the effect of parallel stimulus presentation on the place specificity of the auditory brainstem response (ABR) in human listeners. Frequency-specific stimuli do not guarantee a response place on the cochlea corresponding only to that characteristic frequency – especially for brief and high-level stimuli. Masking techniques can ensure place specific responses, and prior modeling has suggested parallel presentation of frequency-specific stimuli improves place specificity. We tested this hypothesis experimentally here, comparing the place specificity of responses to serial and parallel stimuli at two stimulus frequencies and three stimulus rates.MethodsStimuli were presented alongside high-pass filtered noise with a varied cutoff frequency. Latencies of the ABRs were examined to assess place specificity of responses. Response bands were derived by subtracting responses from different high pass noise conditions. The response amplitude from each derived response band was then used to determine how much individual frequency regions of the auditory system were contributing to the overall response.ResultsWe find that parallel presentation improves place specificity of ABRs for the lower stimulus frequency and at higher stimulus rates. At a higher stimulus frequency, serial and parallel presentation were equally place specific.ConclusionParallel presentation can provide more place specific responses than serial for lower stimulus frequencies. The improvement increases with higher stimulus rates and is in addition to the parallel ABR’s primary benefit of faster test times.
