摘要:
在听觉大脑中，一些神经元表现出对一个重复刺激的特异性适应(stimulus-specific adaptation, SSA)。SSA从中脑到初级听皮层(primary auditory cortex, AI)都存在。研究发现SSA强烈表达在听觉丘脑的主要核团，即内侧膝状体(medial geniculate body, MGB)的非丘系区域内。本文我们将重点介绍听觉丘脑MGB神经元的SSA研究和听觉中枢(即丘脑)在检测声音方面的重要性。
Abstract:
Some neurons show specific adaptation to repetitive stimulation (stimulus-specific adaptation, SSA) in auditory cortex (AC). SSA exists from mid-brain to primary auditory cortex (AI). Studies find that SSA intensely expressed in nucleus of auditory thalamus, the non-lemniscus area of medial geniculate body (MGB). Here we focus on the researches on SSA of MGB and the importance of the auditory thalamus in sound detecting.
