• BAEPs
  • BAEPs are highly sensitive to auditory conduction defects, but the findings are not pathologically specific. (oup.com)
  • Important factors that need to be considered for accurate interpretation of BAEPs include the patient's age, sex, and auditory acuity. (oup.com)
  • The diagnostic yield of BAEPs has been confirmed in patients with acoustic neuromas, MS, or intra-axial brain stem lesions involving the auditory pathways. (oup.com)
  • audiometry
  • It is divided into two sections - Part 1: Audiometry, using Auditory Evoked Potentials (AEP) to Determine Hearing Thresholds of a Number of Cohorts of Salmon and Part 2: The Impact of Pile-Driving Playback on the Behaviour and Physiology of Atlantic salmon (Salmo salar). (gov.scot)
  • Abnormal
  • It is possible that abnormal auditory input during the first two years of life may increase a child's risk for amblyaudia, although the precise relationship between deprivation timing and development of amblyaudia is still unclear. (wikipedia.org)
  • periphery
  • The term "lazy ear" has been used to describe amblyaudia although it is currently not known whether it stems from deficits in the auditory periphery (middle ear or cochlea) or from other parts of the auditory system in the brain, or both. (wikipedia.org)
  • Stimulation
  • A significant deficit in a child's ability to use and comprehend expressive language may be seen in children who lacked auditory stimulation throughout the critical periods of auditory system development. (wikipedia.org)
  • Electrocochleography (abbreviated ECochG or ECOG) is a technique of recording electrical potentials generated in the inner ear and auditory nerve in response to sound stimulation, using an electrode placed in the ear canal or tympanic membrane. (wikipedia.org)
  • By analogy with the steady-state response of a resonant circuit that follows the initial transient response he defined an idealized steady-state evoked potential (SSEP) as a form of response to repetitive sensory stimulation in which the constituent frequency components of the response remain constant with time in both amplitude and phase. (wikipedia.org)
  • N100
  • It is often referred to with the following P200 evoked potential as the "N100-P200" or "N1-P2" complex. (wikipedia.org)
  • The auditory N100 is generated by a network of neural populations in the primary and association auditory cortices in the superior temporal gyrus in Heschl's gyrus and planum temporale. (wikipedia.org)
  • Neuromagnetic research has linked it further to perception by finding that the auditory cortex has a tonotopic organization to N100. (wikipedia.org)
  • There are three subtypes of adult auditory N100. (wikipedia.org)
  • N100b or vertex N100, peaking at 100 ms. T-complex N100a, largest at temporal electrodes at 75 ms T-complex N100c, follows N100a and peaks at about 130 ms. The two T-complex N100 evoked potentials are created by auditory association cortices in the superior temporal gyri. (wikipedia.org)
  • detection
  • These recordings are used in many different clinical situations--the identification of hearing impairment in newborn infants, the detection of tumors on the auditory nerve, the diagnosis of multiple sclerosis. (pluralpublishing.com)
  • We assessed the effects of chronic administration of a subanesthetic dose of ketamine on contextual fear conditioning, detection of pitch deviants and auditory gating. (pubmedcentralcanada.ca)
  • The test is performed by an otologist or audiologist with specialized training, and is used for detection of elevated inner ear pressure (endolymphatic hydrops) or for the testing and monitoring of inner ear and auditory nerve function during surgery. (wikipedia.org)
  • latency
  • to characterize the long latency auditory evoked potentials (LLAEP) results N1, P2, N2 and P300 of children with phonological disorder and to verify the improvement of such potentials with speech therapy. (scielo.br)
  • The absolute latency of wave I was similar to that of adults, generally in the 1st month of life, demonstrating a complete process maturity of the auditory nerve. (scielo.br)
  • deficits
  • however, they do exhibit changes in behavioral tests, suggesting the existence of deficits in temporal or non-auditory processing such as attention (2). (scielo.br)
  • amplitude
  • Gating of the P80 component of auditory evoked potentials was also significantly altered by treatment condition, as ketamine caused a significant decrease in S1 amplitude. (pubmedcentralcanada.ca)
  • A complete audiogram was collected using auditory evoked potential techniques that included measurements of nine frequencies from 4 to 100 kHz presented as sinusoidally amplitude-modulated tones. (biologists.org)
  • To resolve these low-amplitude potentials against the background of ongoing EEG, ECG, EMG, and other biological signals and ambient noise, signal averaging is usually required. (wikipedia.org)
  • Since a SSEP can be completely described in terms of the amplitude and phase of each frequency component it can be quantified more unequivocally than an averaged transient evoked potential. (wikipedia.org)
  • Nevertheless
  • Nevertheless, children with histories of auditory deprivation secondary to these diseases can experience amblyaudia for years after their hearing has been restored. (wikipedia.org)
  • otitis
  • Therefore, the objective of this study was to characterize the results of LLAEP obtained in children with phonological disorder and to investigate the development of the potential after Speech therapy as well as to correlate the development of potentials and the history of otitis and severity of the phonological disorder. (scielo.br)
  • Recurrent ear infections (otitis media) are the leading cause of temporary auditory deprivation in young children. (wikipedia.org)
  • neural
  • FFRs have the potential to be used to evaluate the neural representation of speech sounds processed by different strategies employed by users of cochlear implants, primarily identification and discrimination of speech. (wikipedia.org)
  • neurons
  • The depolarized hair cell releases neurotransmitters across a synapse to primary auditory neurons of the spiral ganglion. (wikipedia.org)
