Abstract

Bimodal neurons in the rattlesnake tectum, which receive sensory input from the retina and from the infrared-sensing pit organ, exhibit novel, highly nonlinear cross-modality interactions. Some units respond only to simultaneous bimodal stimulation. Others respond to only one of the two modalities, but show greatly enhanced or depressed responses when stimulated simultaneously in the second modality. These cross-modality interactions may play an important role in recognizing and orienting toward biologically important objects.

摘要

响尾蛇视顶盖中的双峰神经元接收来自视网膜和红外感应窝器官的感觉输入,呈现出新颖的、高度非线性的跨模态相互作用。一些单元仅对同时的双峰刺激做出反应。其他单元仅对两种模态中的一种做出反应,但在第二种模态中同时受到刺激时,会表现出大大增强或减弱的反应。这些跨模态相互作用可能在识别生物重要物体并朝向其定向方面发挥重要作用。
