摘　　要：OBJECTIVE: To use infrared thermography to take cat cerebral cortical temperature in order to visualize the temperature of its entire cerebral cortex as an image. METHODS: After performing craniotomy for exposure of cerebral hemispheres in 52 cats, their cortical temperatures were displayed and analyzed by computerized infrared thermovision. RESULTS: The temperature distribution of the cerebral cortex was uneven, with a maximum difference of 2.3 degrees C among different cortical areas. The temperature in the cortical anterior-inferior area (including the Ant. Ectosylvian, the lower section of Mid. Ectosylvian and the Ant. Sylvian) was higher compared to the temperature in the posterior-super-parts (Post. Suprasylvian, Mid. Suprasylvian, Post. Lateral and Ant. Lateral). Locations with higher or lower temperatures showed little change within three days after craniotomy, and the cortical temperature held steady. CONCLUSION: The use of cortical infrared thermo-images for display of cat cortical temperature is possible and has many advantages over traditional methods. This new neuroimaging method has a practical value in neurological research.目的　建立一种新的大脑皮层温度图像显示方法观察和分析大脑皮层的温度分布。方法　 5 2只家猫在开颅后 ,用红外热像仪显示大脑皮层的温度图像 ,并用计算机提取和分析皮层各区温度数值。结果　大脑皮层温度分布不均匀 ,不同区域温度高低最大差值在 2 3℃左右 ;皮层前下部 (前外薛氏回、中外薛氏回下段、前薛氏回等 )温度较高 ,后上部 (后上薛氏回 ,中上薛氏回后段 ,后总回及前总回 )等温度较低 ;术后 3天内皮层高低温区的位置无大变化 ,温度稳定性较好。结论　大脑皮层的红外热像图显像清晰 ,本文建立的观察和显示方法是成功的 。
