RESUMO
<p><b>OBJECTIVE</b>To use infrared thermography to take cat cerebral cortical temperature in order to visualize the temperature of its entire cerebral cortex as an image.</p><p><b>METHODS</b>After performing craniotomy for exposure of cerebral hemispheres in 52 cats, their cortical temperatures were displayed and analyzed by computerized infrared thermovision.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
