Focal electric stimulation of the auditory cortex, 30-minute repetitive acoustic stimulation and auditory fear conditioning each evoke shifts of the frequency-tuning curves (hereafter, best frequency [BF] shifts) of cortical and collicular neurons. The short-term collicular BF shift is produced by the corticofugal system and primarily depends on the relationship in BF between a recorded collicu...

BACKGROUND The goal of the fMRI experiment was to explore the involvement of central auditory structures in pathomechanisms of a behaviorally manifested auditory temporary threshold shift in humans. MATERIAL AND METHODS The material included 18 healthy volunteers with normal hearing. Subjects in the exposure group were presented with 15 min of binaural acoustic overstimulation of narrowband noi...

Abstract Hydraulic fracture propagation has a great influence on reservoir reconstruction in shale gas exploitation. The study mechanism of hydraulic is important. Based the fluid-solid coupling theory, criterion under pressure deduced this paper. In combination with large-scale true triaxial experiment and numerical simulation, law researched, obtained. results show that will produce tensile f...

Optogenetics has become an important research tool and is being considered as the basis for several neural prostheses. However, few studies have applied optogenetics to the auditory brainstem. This study explored whether optical activation of the cochlear nucleus (CN) elicited responses in neurons in higher centers of the auditory pathway and whether it elicited an evoked response. Viral-mediat...

transcranial current stimulation (tcs) is a neuromodulation method in which the patient is exposed to a mild electric current (direct or alternating) at 1-2 ma, resulting in an increase or a decrease in the brain excitability. this modi.cation in neural activities can be used as a method for functional human brain mapping with causal inferences. this method might also facilitate the treatments ...

A clustered volume acquisition functional MRI pulse sequence was modified to assess the response to the acoustic noise of echo-planar imaging in the auditory cortex and to determine whether it is possible to obtain data which is relatively free of acoustic contamination. The spatial location and strength (percent signal change) of cortical responses to the imager noise were examined by introduc...

Purpose The settings of 3 electrical stimulation parameters were adjusted in 12 speakers with Parkinson's disease (PD) with deep brain stimulation of the subthalamic nucleus (STN-DBS) to examine their effects on vowel acoustics and speech intelligibility. Method Participants were tested under permutations of low, mid, and high STN-DBS frequency, voltage, and pulse width settings. At each sess...

Objectives: The effect of deep brain stimulation (DBS) on voice quality in 8 patients with multiple sclerosis (MS) was examined instrumentally and perceptually. Methods: First, vowel productions of the patients (produced with and without stimulation) and of a group of 16 healthy control speakers were analysed. Second, the acoustic signals of the same vowel productions were prepared for perceptu...

Assessing the correspondence between spontaneous and stimulus-driven neural activity can reveal intrinsic properties of the brain. Recent studies have demonstrated that many large-scale functional networks have a similar spatial structure during spontaneous and stimulus-driven states. However, it is unknown whether the temporal dynamics of network activity are also similar across these states. ...
