Central response to infra-red stimulation of the pit receptors in a crotaline snake, Trimeresurus flavoviridis.

摘要: 1. Both action potentials and evoked were recorded from the tectum opticum of a crotaline snake, Trimeresurus flavoviridis , in response to infra-red stimulation facial pit organs. Action single units throughout tectum. 2. Most responded contralateral stimulation, while some both ipsi- stimulation. 3. Firing patterns tonic, phasic, or phasic-tonic, depending on position stimulus type unit being recorded. 4. Sensitivity movement was observed. 5. All differed peripheral firing patterns. 6. frequency directly proportional intensity. 7. Measurements made vertical horizontal fields units. 8. Background discharge noted all its nature discussed. 9. The integrative function regard perception also discussed, as well possibility stereoscopic perception.
