A computer model for the pre-tectum infrared vision system of the rattlesnake

This dissertation decomposes the eye and pit pre-tectum biological systems of the rattlesnake into their various parts such that a computer model for the infrared system can be constructed. The path the input signal takes for both systems is discussed along with the key parts to the pre-tectum part of these systems. In addition, each part of the infrared system is broken down into its physical components, known functions, and possible functions. The hunting methods along with the physical design and capabilities of the rattlesnake's prey are discussed to aid in determining the functional capabilities of the pre-tectum infrared vision system. Using this information, a computer model is constructed that will mimic the capabilities and functionality of this system. The model is modular, allowing for various possible arrangements to account for the different possible functionality within the pre-tectum infrared vision system. It is hoped that by accurately modeling the pre-tectum part of the infrared visual system of the rattlesnake further insight can be gained as to how the rattlesnake fuses infrared and visual signal information together in the optic tectum.
