Reptiles have been characterized by relevant number of papers as well-known animal models in biomedical research and neuroethology due to their ancestral evolutionary relationship with birds and mammals, leading to further hypothesis that the dorsal ventricular ridge (DVR), the dorsal pallia of amphibians and the isocortex of mammalian brains share a common anatomical origin. The objective of this study was to assess the morphologic features and measurement of brain waveforms of Iguana iguana through Visual Evoked Potentials (VEP). This research employed six healthy and ophthalmologically-suited iguanas (Iguana iguana), with computerized tomography brain scans followed by VEP under simple temporary physical restrain. The systematic study of VEP individually analyzed both eyes of the Iguana iguana species displaying a response that consisted of five steady waveforms during the first 200 msec, further characterized as P1, N1, N2, P2 and P3. Comparison among these waveforms revealed no significant differences.
