The hypoxic models mimic 8000 m high level were established in a high-altitude decompression chamber. Injecting the tracer of CB into the rat's lateral ventricles, we investigated the distribution of the distal CSF-CNs in the DR. The single and double immunohistochemistry staining with antibodies to Fos and CB were used to observe the expression of Fos in the distal CSF-CNs in the DR.

Like the Gila monster, which attacks with venom, inflicting festering but fatal wounds? Or merciless assassin snakes with switchblade fangs as sharp as hypodermic needles and enough poison to kill ten people. And they are smart-alligators that send coded messages, iguanas that run on water and the green turtle that uses magnetic crystals in its brain to navigate across the ocean. A Diamondback rattlesnake can inject a tracer to track its dying prey and baby snakes fish for trout with their tongues!
