視覺如何聆聽：麻醉大鼠初級視覺皮質中的聽覺預測處理

// When vision listens: auditory predictive processing in primary visual cortex of anesthetized rats

本研究透過老鼠初級視覺皮層（V1）第IV至VI層神經記錄，探討V1是否編碼聽覺預測誤差｜V層至VI層神經元對意外聲音刺激反應較強，顯示對預測誤差有選擇性反應｜不同層出現不同反應模式，V層呈現快速短暫活動，VI層則為持續性活動，支持V1作為多感官預測整合中心的角色。

// This study investigated whether primary visual cortex (V1) encodes auditory prediction errors using neuronal recordings from rat V1 layers IV-VI during auditory oddball tasks. Neurons in layers V-VI responded stronger to unexpected (deviant) tones, indicating encoding of prediction errors rather than simple repetition effects. Responses varied by layer, with faster, phasic activity in layer V and sustained activity in layer VI. The findings suggest V1 infragranular circuits integrate auditory predictions, supporting its role as a multisensory predictive hub.
