Neurobiology of Chameleons

Hey everyone,

So I had a chameleon pass away recently from what we believe was a stroke and since then I have been on this kick to understand the chameleon brain. Are there any review articles that examine chameleon neurobiology/neuroanatomy, perhaps with an emphasis on the CNS? I have been all up and down PubMed (mostly Gadi Katzer and of course Chris Anderson) but nothing's quite scratching that itch. I understand they're not as popular a model organism as mice or flies or chicks, but someone's gotta understand something about the critters. Any help is appreciated. Thanks for reading!
 
Also interested in books, book chapters, and interesting PNS articles; I will take anything I can get as long as it's good research.
 
Unfortunately there isn't a ton of work out there. I briefly summarized the neural anatomy in my "Chameleon Anatomy" chapter in "The Biology of Chameleons", and there is a section on Neurophysiology in the "Chameleon Physiology" chapter of the same book. Here are a few additional references to relevant works as well:

These look great, I'll begin tracking down these articles right away. Thanks!
 
Hi @Chris Anderson,
I'm curious if there are any universities that you know that currently study chameleon behavior, physiological processes, anything of that sort?

Yeah, there are a few. Some labs focus more on chameleons than others, and in some cases, its just a single graduate student working on a project with them, but not really a focus in the lab. Some of that work is done at undergraduate only institutions, while other labs working on chameleons have graduate programs, etc. It really just depends on what you're looking for information on. My lab works a lot with chameleons, including studies on biomechanics, physiology, behavioral ecology, etc. There are definitely others though if you have something specific you're looking for?
