Oh maaaan, I would love to attend that. Not too far to drive (albeit a long one) but being out of work nixes any possibility and if I do get a job, I can't take leave. Lottery, where are you? I wish these seminars would place the talks on-line afterwards even if they charged a small fee ...

Shoot, I was going to PM Robyn and NeuroBadger when I saw the squid topic

Does nociceptive sensitization confer fitness benefits on injured squid, Loligo pealeii?
Robyn J. Crook 1, 2*, Roger T. Hanlon3 and Edgar T. Walters1

Neural control of dynamic structural coloration in squid iridophores.
Trevor J. Wardill1*, Paloma T. Gonzalez Bellido1*, Robyn Crook 2 and Roger T. Hanlon1

Also one should note this presentation

Dynamics of chromatophore response to visual stimulation
Stavros P. Hadjisolomou 1* and Frank W. Grasso1

Starvos,
Will your paper be available outside the conference? Reading the abstract it occurred to me that the described reaction seems similar to (albeit perhaps opposite) the reaction of the eye pupil after a flash of light (or quick change of light) which dove-tails a bit with the possibility (and something I have wondered aloud about so am interested in watching what is found) of cephs seeing color with their skin. Cool stuff!

This looks amazing. Expensive!! But hard to miss. Thanks for summarizing the ceph-related stuff.

D, these results are going to be published later this year, as part of a special issue on cephalopods in a journal for invertebrate neuroscience (not sure of exact dates, they haven't been posted yet). I don't think it's going to be open access, but will send you a copy when the article gets accepted and published.

Something to think about: if driving to, and staying overnight at Maryland is not a problem, then maybe we can arrange a get-together with the people presenting there for a couple of pints after talks are done- get to know each other and talk more about cephalopod behaviour.

[DWhatley]

Unfortunately, (or fortunately) I am in the middle of some hopefuls for employment. I have a psedu-uncle in Baltimore so I might be able to bunk in with him for a night but that is a loooong drive for an evening out. Don't count me out yet though, I should have a better feel for my status in the next two weeks.

 

[neurobadger]

Alas, I am going to be stuck in Massachusetts when the neuroethology conference happens. Robyn and I are chugging away on our injury study.

I am amused by how many of the people who've written these papers I've met.

[GPO87]

Just an update: The presentors at the Cephalopod International Advisory Council Symposium are top notch! There is some very exciting ceph research happening all over the world right now! I will make sure to give a review of the week when I get home... but for now, must get to work. My talk is tomorrow morning! Cross your tentacles for me!

[Stavros]

SICB '13 was a great meeting. I believe it had the most ceph-related presentations than any other meeting I've been to so far (excluding the ceph-specific ones such as Euroceph, CIAC, etc.) The great thing about SICB is not so much the topics themselves, but the range and variety of approaches employed to understand such topics.

In short, cephalopod presentations covered:

- cephalopod vision and coloration (evolution, development of optic lobes, lens size, water depth, pigmentation, molecular basis of),
- cephalopod movement (squid startle response, fin usage),
- auditory systems (sepia reacting to sound),
- population, mating systems (fascinating talk on female proceptive behavior in octopus),
- and peripheral sensory neurons (mechanoreception, light detection) which undoubtedly received the most interest.

My personal favorite of the meeting was a talk by Jean Alupay on costs and benefits of losing an arm in octopuses. She showed great footage of how an arm moved right after being separated from the rest of the animal. The suckers were attached to the glass wall of the tank and carried the arm sideways by propagation of attach/detach movement. This indicates a stored motor program in the periphery (arm) that does not depend on central control (brain). This behavior can benefit the octopus by distracting a predator while it makes its escape. That resonated with me (that is, I'm biased to like this talk) because of my previous project on octopus suckers and while I want to stay focused on my current project, it raised a lot of questions that I'd like to see them answered.

Since the meeting was in San Francisco, I used the opportuinity to visit the Steinhart aquarium and had a behind-the-scenes tour of the cephs there, courtesy of the kind folks at the Academy of Sciences. It's definitely worthwhile visiting this aquarium if you happen to be in the area, it has fantastic displays of the dwarf sepia bandensis, Pfeffer's flamboyant cuttlefish and a curious giant Pacific Octopus.

I wish there was a way to make these presentations public, especially for a forum such as this one. I've shared the idea with some of the people listed above and all showed interest in it, but it's going to take more coordination to bring forward. Something to keep in mind for the future.

Can't go home for the holidays and not talk about nautiluses!!!

Mini-TONMOCON???

[DWhatley]

Greg, This sounds kind of self evident but there are 10 states with cities named "Phoenix" (including my home state of GA). The headliner shows the state of your institution (Phoenix, NY exists), sooo, is the Phoenix Zoo IN Phoenix, AZ or Phoenix, NY or somewhere else?

 

[gjbarord]

Good point. I grew up in the biggest Phoenix (in Arizona) so I don't think of any of those smaller little brother cities, haha. But yeah, it is in Phoenix, AZ.
