在没有感觉刺激的情况下,大脑中的自发活动已被证明在多个时空尺度上表现出组织性。在猕猴的听觉皮质中,对声刺激的反应是在外侧沟的颞上平面(STP)上沿尾骨方向排列的多个相邻的频率图内进行的。在这里,我们使用慢性微皮质脑电图术来研究感觉图和听觉皮质中自发神经波动之间的对应关系。我们首先绘制了96个电极的纯音组织图,这些电极沿着初级和更高级的听觉皮质横跨大约两厘米。在不同的会话中,我们观察到相同部位的自发活动表现出空间协变性,这反映了STP的张力地图。这一观察结果表明,清醒猴子感觉皮质中的功能组织和自发神经活动之间存在密切关系。
In the absence of sensory stimuli, spontaneous activity in the brain has been shown to exhibit organization at multiple spatiotemporal scales. In the macaque auditory cortex, responses to acoustic stimuli are tonotopically organized within multiple, adjacent frequency maps aligned in a caudorostral direction on the supratemporal plane (STP) of the lateral sulcus. Here we used chronic micro-electrocorticography to investigate the correspondence between sensory maps and spontaneous neural fluctuations in the auditory cortex. We first mapped tonotopic organization across 96 electrodes spanning approximately two centimeters along the primary and higher auditory cortex. In separate sessions we then observed that spontaneous activity at the same sites exhibited spatial covariation that reflected the tonotopic map of the STP. This observation demonstrates a close relationship between functional organization and spontaneous neural activity in the sensory cortex of the awake monkey.
