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). All participants underwent behavioral evaluation of temporal auditory processing, composed of Duration Pattern Sequence Test (DPS), Pitch Pattern Sequence Test (PPS), Random Gap Detection Test (RGDT) and electrophysiological evaluation - Long Latency Auditory Evoked Potential - P300. GI also answered a specific questionnaire to characterize musical practice.
Results: We observed statistically significant differences with superior performance of GI compared with GII in all behavioral tests (p<0.001*). The groups' performance was similar regarding the latency and amplitude parameters analyzed from LLAEP-300 data (p>0.05).
Conclusion: The findings show a positive influence of musical practice toward the improvement of auditory abilities of temporal ordering and resolution. All participants presented adequate cortical functioning of the central auditory nervous system, without significant differences between musicians and non-musicians when considering P300 amplitude and latency.

Introduction: Chronic low back pain (CLBP) is a global health issue, and its nonspecific causes make treatment challenging. Understanding the neural mechanisms of CLBP should contribute to developing effective therapies.
Objectives: To compare current source density (CSD) and functional connectivity (FC) extracted from resting electroencephalography (EEG) between patients with CLBP and healthy controls and to examine the correlations between EEG indices and symptoms.
Cochlear implantation in adults with acquired single-sided deafness improves cortical processing and comprehension of speech presented to the non-implanted ears: a longitudinal EEG study.

Former studies have established that individuals with a cochlear implant (CI) for treating single-sided deafness experience improved speech processing after implantation. However, it is not clear how each ear contributes separately to improve speech perception over time at the behavioural and neural level. In this longitudinal EEG study with four different time points, we measured neural activity in response to various temporally and spectrally degraded spoken words presented monaurally to the CI and non-CI ears (5 left and 5 right ears) in 10 single-sided CI users and 10 age- and sex-matched individuals with normal hearing.

To describe the distribution of jugular bulb position and pneumatization of posterior lip of internal auditory meatus (IAM) in patients with vestibular schwannoma (VS). This retrospective study included 43 patients who had a thin slice (< 2 mm) CT temporal bone for preoperative planning of retrosigmoid approach for excision of VS between March 2011 and March 2021. On computed tomography (CT), high riding jugular bulb was defined by its relationship to IAM and correlated with type of jugular bulb according to Manjila et al.

Introduction: Cumulative blood pressure metrics may provide greater precision for measuring temporal risk exposure, especially in later life where data are mixed regarding associations of high blood pressure (BP) on cognitive function. We examined the relationship between greater cumulative exposure to high BP in later life and several domains of cognitive function.
Methods: Individual cognitive assessment scores and BP measurements in older adults (age ≥70 years) at baseline and over approximately 8 years of follow-up were available in the population-based Canadian Victoria Longitudinal Study (VLS) and Swedish Gothenburg H70 Birth Cohort Studies (H70).
