耳鳴抑制之神經指標：起始-終止與感覺閘控聽覺誘發電位隨刺激頻率及耳鳴嚴重度變化

// Neural Indicators of Inhibition in Tinnitus: Onset-Offset and Sensory Gating Auditory Evoked Potentials Vary by Stimulus Frequency and Tinnitus Severity

本研究探討刺激頻率與耳鳴嚴重度對聽覺誘發電位（AEPs）抑制作用的影響｜26名耳鳴患者與匹配對照組比較，發現寬頻噪音誘發最大反應，高頻刺激則降低振幅｜耳鳴嚴重者神經抑制功能減弱，顯示生理抑制缺陷與心理因素相關。

// This study examined how stimulus frequency and tinnitus severity affect auditory evoked potentials (AEPs) related to inhibition. Using varied frequency stimuli, AEPs were recorded from 26 tinnitus patients and matched controls, revealing that broadband noise elicited the strongest responses while higher frequencies reduced amplitude. High-frequency tinnitus did not correlate with abnormal high-frequency AEPs, but individuals with moderate to severe tinnitus showed reduced sensory gating, indicating decreased neural inhibition. These findings suggest that tinnitus severity and related psychological factors are linked to underlying physiological inhibition deficits.
