Auditory temporal resolution and backward masking in musicians with absolute pitch.

Among the many questions regarding the ability to effortlessly name musical notes without a reference, also known as absolute pitch, the neural processes by which this phenomenon operates are still a matter of debate. Although a perceptual subprocess is currently accepted by the literature, the participation of some aspects of auditory processing still needs to be determined. We conducted two experiments to investigate the relationship between absolute pitch and two aspects of auditory temporal processing, namely temporal resolution and backward masking.

 This study aimed to investigate central auditory processing performance in children with migraine and compared with controls without headache.  Twenty-eight children of both sexes, aged between 8 and 12 years, diagnosed with migraine with and without aura, and a control group of the same age range and with no headache history, were included. Gaps-in-noise (GIN), duration pattern test (DPT), synthetic sentence identification (SSI) test, and nonverbal dichotic test (NVDT) were used to assess central auditory processing performance.

DFT:B3LYP/3-21G theoretical insights on the confocal Raman experimental observations in skin dermis of healthy young, healthy elderly, and diabetic elderly women.

In the confocal Raman spectra of skin dermis, the band area in the spectral region of proline and hydroxyproline varies according to the age and health condition of the volunteers, classified as healthy young women, healthy elderly women, and diabetic elderly women. Another observation refers to the intensity variation and negative Raman shift of the amide I band. To understand these effects, we adopted a model system using the DFT/B3LYP:3-21G procedure, considering the amino acid chain formed by glycine, hydroxyproline, proline, and alanine, which interacts with two and six water molecules.

Reproducibility (test-retest) of vestibular evoked myogenic potential.

Introduction: There is still no consensus in the literature as to the best acoustic stimulus for capturing vestibular evoked myogenic potential (VEMP). Low-frequency tone bursts are generally more effective than high-frequency, but recent studies still use clicks. Reproducibility is an important analytical parameter to observe the reliability of responses.
