My name is Joseph, a senior biologist at the University of Scranton. I am currently conducting research on morphometric of ants, but we are having some issues. I was curious if you had any papers on the histology of ants, specific on the nervous system or their notochord. Any species will do at the moment, we are just used to looking at mammalian tissue, and not insect samples. Hope to hear back from you soon!
Thanks for writing! We contacted an expert on the nervous system of ants, Dr. Wulfila Gronenberg; here is what he had to say:
the nervous systems of insects has been well described for many taxa, and ants are no exception. The basic design is not unlike what you see in vertebrates - they have a brain with visual, olfactory, tactile and other centers including higher order central processing centers, and the have a ventral nerve cord analogous (and probably homologous) to the vertebrate spinal cord and which comprises the sensory and motor centers that control walking, flight (in winged males and females) and abdominal functions. If you want to learn more about ant nervous systems I suggest a review paper that I have written a few years ago:
Gronenberg W (2008) Structure and function of ant (Hymenoptera: Formicidae) brains: Strength in numbers. Myrmecological News 11:25-36.
If you (or anybody else) have difficulties getting hold of the paper, just send me an email: firstname.lastname@example.org.
If your question was more about histological and technical aspects (how to dissect, stain or measure ant brains), please let me know and I can point out some more specific information to you.
All the best"
