Purpose: To evaluate ordinary behavioral pattern suppression performance of individuals with tinnitus under disruptive effect using Stroop Color Word Interference Test-TBAG Form (SCWT), and to determine the impact of acoustic stimulus on this performance.
Methods: 40 individuals with subjective tinnitus at Slight and higher severity according to Tinnitus Handicap Inventory (THI) (16 females, 24 males; mean age: 42.02 ± 10.00) (Study group), and 40 healthy individuals (Control group) (18 females, 22 males; mean age: 38.85 ± 10.25) were included in this study. All individuals were subjected to audiological evaluation. SCWT was applied with and without acoustic stimulus (NB noise), and test completion durations were recorded.
Results: It was determined that the duration for completion of 5 sections of SCWT, both in the presence of and without acoustic stimulus, was longer in the Study group than the control group. In the presence of acoustic stimulus, it took longer for the individuals with tinnitus to complete sections 4 and 5, and the control group to complete sections 3, 4 and 5 in SCWT in comparison with the lack of acoustic stimulus.
Conclusion: It was determined that SCWT performance of the individuals with tinnitus was worse than the individuals without tinnitus, both in the presence of and without acoustic stimulus. It was found that SCWT performances of both groups with acoustic stimulus were better than their test performances without acoustic stimulus.

Alteration of responses to salient stimuli occurs in a wide range of brain disorders and may be rooted in pathophysiological brain state dynamics. Specifically, tonic and phasic modes of activity in the reticular activating system (RAS) influence, and are influenced by, salient stimuli, respectively. The RAS influences the spectral characteristics of activity in the neocortex, shifting the balance between low- and high-frequency fluctuations.

French and German poetry are classically considered to utilize fundamentally different linguistic structures to create rhythmic regularity. Their metrical rhythm structures are considered poetically to be very different. However, the biophysical and neurophysiological constraints upon the speakers of these poems are highly similar.

Tinnitus is a heterogeneous hearing disorder with no cure at present, but some treatments, such as a combination of counselling and sound therapy, can alleviate the discomfort it causes. The sound therapy efficiency depends on both the type of sound stimulus and the time of exposure. This study describes the fundamentals of a personalized sound therapy that stimulates the auditory system with either continuous or sequential sounds whose spectra are adjusted to the hearing levels of the participants.

The effective and translational strategy to regenerate knee meniscal fibrocartilage remained challenging. Herein, we first identified vascular smooth muscle cells (VSMCs) transdifferentiated into fibrochondrocytes and participated in spontaneous meniscal regeneration using smooth muscle cell lineage tracing transgenic mice meniscal defect model. Then, we identified low-intensity pulsed ultrasound (LIPUS) acoustic stimulus enhanced fibrochondrogenic transdifferentiation of VSMCs in vitro and in vivo.

The perceptual aspects of masking have been actively studied for several decades, and particular emphasis has been placed on masking of speech by other speech sounds. The neural effects of such masking, especially at the subcortical level, have been much less studied, in large part due to the technical limitations of making such measurements.
