More Neuropeptide Soup and Crayfish

In addition to presenting a poster today, I walked around the sleep and circadian rhythm posters, two of which included my lab mates. A few of the circadian posters presented by Larry Morin of Stonybrook and Marilyn Duncan of U of Kentucky illustrated the importance of NPY for photic entrainment and age-related changes in VIP expression, respectively. My lab mates presented similar work (see SFN Preview Post).

I also saw a fascinating poster on the effects of caffeine administered systemically in crayfish; like humans and Drosphila, crayfish not only exhibit increased arousal during the sleeping period, but it is equally reflected in the EEG and spectral. Even my ecology friends who study crayfish will find that study fascinating (I hope).
