Neuronal activity was extracellularly recorded from the nucleus dorsolateralis posterior thalami (DLP) of anesthetized pigeons. The sensitivity of individual cells to stimuli of different sensory modalities: somatosensory, visual and auditory was investigated. A substantial population of the DLP neurons responded to mechanical stimulation of large, often bilateral areas of the animal's body surface. No somatotopic organization could be detected. The functional properties of these neurons resembled those described for mammalian nucleus posterior thalami neurons. The visually responsive cells could be driven from large areas of the visual field. Auditory sensitive neurons were optimally activated by wideband noise. Twenty-nine percent of the DLP recorded neurons showed polysensory properties responding either to somatosensory and visual or to somatosensory and auditory stimuli.
在麻醉鸽子的丘脑后外侧背核（DLP）进行细胞外神经元活动记录。研究了单个细胞对不同感觉模态刺激的敏感性，这些刺激包括躯体感觉、视觉和听觉。大量的DLP神经元对动物体表大面积区域（通常是双侧）的机械刺激有反应。未检测到躯体定位组织。这些神经元的功能特性类似于哺乳动物丘脑后核神经元所描述的特性。视觉反应细胞可由视野的大面积区域驱动。听觉敏感神经元被宽带噪声最佳激活。记录的DLP神经元中有29%表现出多感觉特性，对躯体感觉和视觉刺激或对躯体感觉和听觉刺激有反应。
