Desenvolvimento de estímulos dinâmicos térmicos para análise do sistema sensorial infravermelho em serpentes

Abstract

The present work describe a creation of an experimental environment capable of measuring the neural response of vision (thermal) -in snakes -when stimulated by infrared radiation.There will be a creation of artificial dynamic stimuli of which the temperature and displacement velocity can be controlled. The response of the snake, when presented to these stimuli, captured directly from the brain (tecto optic), which corresponds to visual and infrared process in the central nervous system of the rattlesnake. We showed that with these stimuli created, it is possible to obtain experimental data which will allow analysis of sensitivity of the infrared sensory system in relation to contrast in temperature and speed of movement of false prey.
