Brainstem frequency-following responses (FFRs) probe the neural transcription of speech/music, auditory disorders, and plasticity in subcortical auditory function. Despite clinical and empirical interest, the response's neural basis remains poorly understood. The current study aimed to more fully characterize functional properties of the human FFR (topography, source locations, generation). Spe...

Enzyme replacement therapy (ERT) has improved the quality of life in patients with Gaucher disease (GD). An emerging concern is whether ERT can also halt the neurologic progression in type 3 GD. The authors examined the auditory brainstem response (ABR) in eight children with type 3 GD undergoing high-dose ERT and found a consistent deterioration in ABR response. They conclude that ERT does not...

Background. Developing interventions to improve medication adherence may depend upon discovery of novel behavioral risk factors for nonadherence. Objective. Explore the effects of emotional response (ER) on adherence to antihypertensive medication and on systolic blood pressure (SBP) improvement. Design. We studied 101 adults with diabetes and hypertension. The primary outcome, 90-day "percenta...

We introduce a new approach, the cross-phaseogram, that captures the brain's ability to discriminate between spectrotemporally dynamic speech sounds, such as stop consonants. The goal was to develop an analysis technique for auditory brainstem responses (ABRs) that taps into the sub-millisecond temporal precision of the response but does not rely on subjective identification of individual respo...

A linear stability analysis is performed on the Immersed Fibre Problem, which models the motion of elastic bres immersed in an incom-pressible uid. The results are used to gain insight into the physical problem, and also to help in designing an eecient, moving grid numerical scheme. Computations are performed for a two-dimensional model problem and the second-order convergence of the scheme is ...

In 95 percent of the cases, patients with acoustic neuromas will have some magnitude of hearing loss in the affected ear. This paper reports on four patients who had acoustic neuromas and normal hearing. Results from the case history, audiometric evaluation, auditory brainstem response (ABR), electroneurography (ENOG), and vestibular evaluation are reported for each patient. For all patients, t...

Two forms of brainstem plasticity are known to occur: an immediate stimulus probability-based and learning-dependent plasticity. Whether these kinds of plasticity interact is unknown. We examined this question in a training experiment involving three phases: (1) an initial baseline measurement, (2) a 9-session training paradigm, and (3) a retest measurement. At the outset of the experiment, aud...

AIM OF STUDY This study investigated the consistency in Auditory Brainstem Response (ABR) waveform evaluations between two audiologists (inter-audiologist agreement) and within each of the audiologist (intra-audiologist agreement). METHODS Two audiologists from one of the audiology clinics in Kuantan, Pahang, Malaysia were involved in this study. Both audiologists were required to identify an...

BACKGROUND A proper sleep system can affect the spine support in neutral position. Most of the previous studies in scientific literature have focused on the effects of customary mattresses on the spinal alignment. To keep the spine in optimal alignment, one can use sleep surfaces with different zonal elasticity, the so called custom-made arrangements. The required stiffness of a sleep surface f...
