We studied the effect of acoustic stimulation on cell composition of auditory brain structures in Krushinskii-Molodkina rats. Significant structural changes in the inferior colliculi of rats with high seizure activity were revealed 1 month after acoustic stimulation. Therefore, this brain structure plays a role in the development of audiogenic epileptic activity.

Purpose: There are challenges in understanding the biomechanics of the human middle ear, and established methods for studying this system show significant limitations. In this study, we evaluate a novel dynamic imaging technique based on synchrotron X-ray microtomography designed to assess the biomechanical properties of the human middle ear by comparing it to laser-Doppler vibrometry (LDV).
Methods: We examined three fresh-frozen temporal bones (TB), two donated by white males and one by a Black female, using dynamic synchrotron-based X-ray microtomography for 256 and 512 Hz, stimulated at 110 dB and 120 dB sound pressure level (SPL).

Short-term memory for sequences of verbal items such as written words is reliably impaired by task-irrelevant background sounds, a phenomenon known as the "Irrelevant Sound Effect" (ISE). Different theoretical accounts have been proposed to explain the mechanisms underlying the ISE. Some of these assume specific interference between obligatory sound processing and phonological or serial order representations generated during task performance, whereas other posit that background sounds involuntarily divert attention away from the focal task.

Introduction: Sickle cell anemia has a genetic origin characterized by an autosomal recessive inheritance pattern. The nervous system may be subject to vaso-occlusion and, consequently, affect the proper functioning of the central portion of hearing.
Objective: To assess central auditory skills and analyze short- and long-latency auditory evoked potentials in children with sickle cell disease.

Background: Transcranial ultrasound stimulation (TUS) has shown promising prospects as a non-invasive neuromodulation technique for both animals and humans. However, ultrasonic propagation characteristics within the brain differ significantly from those in free space. There is currently a lack of comprehensive studies on the effects of skull thickness on focal point position, full width at half maximum (FWHM), and acoustic intensity.
