The nonapeptide Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, isolated in 1977 from the cerebral venous blood of rabbits and named for the EEG changes reported in those experiments. No gene or receptor for it has been identified, which keeps its endogenous origin an open question. Used in rodent EEG and neuroendocrine assays.
