摘要我们研究了豚鼠上丘神经元对视觉和听觉刺激组合的反应。当这些刺激单独呈现时，这些神经元中的一些只对一种模式有反应，另一些对两种模式都有反应，少数神经元对两种模式都没有反应。对于双峰刺激，许多神经元表现出某种形式的跨通道相互作用，其程度和性质取决于两种刺激的相对时间和位置。易化和抑制的相互作用被观察到，偶尔，在同一神经元的不同刺激间间隔发现这两种作用。其对视觉刺激的反应被听觉刺激增强的神经元在浅层被发现。虽然视觉增强和视觉抑制的听神经元遍及大脑皮层深层，但大部分记录在灰质深层。对视觉刺激和听觉刺激分别产生反应的神经元和对双峰刺激产生增强或抑制反应的神经元分布于各深层，但集中在中间灰质层并延伸至视层。
SummaryWe have investigated the responses of neurones in the guinea-pig superior colliculus to combinations of visual and auditory stimuli. When these stimuli were presented separately, some of these neurones responded only to one modality, others to both and a few neurones reliably to neither. To bimodal stimulation, many of these neurones exhibited some form of cross-modality interaction, the degree and nature of which depended on the relative timing and location of the two stimuli. Facilitatory and inhibitory interactions were observed and, occasionally, both effects were found in the same neurone at different inter-stimulus intervals. Neurones whose responses to visual stimuli were enhanced by an auditory stimulus were found in the superficial layers. Although visual-enhanced and visual-depressed auditory neurones were found throughout the deep layers, the majority of them were recorded in the stratum griseum profundum. Neurones that responded to both visual and auditory stimuli presented separately and gave enhanced or depressed responses to bimodal stimulation were found throughout the deep layers, but were concentrated in the stratum griseum intermediale and extended into the stratum opticum.
