Temporal auditory processing in people exposed to musical instrument practice.

Purpose: To investigate the influence of musical instrument practice on temporal auditory abilities and on the results of cortical potentials related to auditory events (P300) in a group of young musicians compared to individuals without experience in musical practice.

Methods: This is a prospective cross-sectional observational study. In total, 34 individuals between 18 and 30 years old, of both sexes, took part and were divided in two groups: Group I (GI), composed of musicians (n=16), and Group II (GII), composed of non-musicians (n=18).

Clinical profile and implications of tinnitus in individuals with and without hearing loss.

Purpose: To compare clinical characteristics of tinnitus and interference in quality of life in individuals with and without associated hearing loss, as well as to discuss the association of quantitative measurements and qualitative instruments.

Methods: A quantitative, cross-sectional and comparative study approved by the Research Ethics Committee (No. 973.

Semen deposition by cervical, transcervical and intrauterine route for fixed-time artificial insemination (FTAI) in the ewe.

Semen deposition through the cervix into the uterus is a difficult technique in ewes and represents the main limiting factor for insemination in this species. The objective of this study was to evaluate the pregnancy rate achieved with a new transcervical insemination method in comparison with conventional cervical and laparoscopic intrauterine techniques. A total of 586 multiparous Corriedale ewes were synchronized for fixed time artificial insemination (FTAI) performed by cervical, transcervical, or intrauterine route at 46-50 h or 52-56 h after progesterone device removal in a 3 × 2 factorial design.

Comparison of auditory event-related potentials between children with benign childhood epilepsy with centrotemporal spikes and children with temporal lobe epilepsy.

The abnormal brain discharges observed in benign childhood epilepsy with centrotemporal spikes (BECTS) and temporal lobe epilepsy (TLE) are located close to areas responsible for auditory and language processing. This study aimed to analyze the results of auditory event-related potentials (P300) in children with BECTS and TLE in order to assess whether the epileptic activity in centrotemporal and temporal regions may compromise the integrity and physiology of auditory system structures. This was a prospective, comparative, and cross-sectional study.

Language and central temporal auditory processing in childhood epilepsies.

Because of the relationship between rolandic, temporoparietal, and centrotemporal areas and language and auditory processing, the aim of this study was to investigate language and central temporal auditory processing of children with epilepsy (rolandic epilepsy and temporal lobe epilepsy) and compare these with those of children without epilepsy. Thirty-five children aged between eight and 14 years old were studied. Two groups of children participated in this study: a group with childhood epilepsy (n=19), and a control group without epilepsy or linguistic changes (n=16).
