The goal of this project was to determine if picrotoxin influences phonotactic selectivity of female crickets when nanoinjected into the supraesophageal ganglion. Adult females of Acheta domesticus were pre-tested for phonotaxis on a treadmill to a range of calling songs with different syllable periods. Following dissection to expose the brain, 9.2 nL of either saline (control group) or 10-5 M picrotoxin (experimental group) was nanoinjected into the supraesophageal ganglion. Post-tests following saline injection (10 min later) were similar to the pre-tests. Picrotoxin-treated females became more phonotactically selective displaying a preference for calling songs with the shorter syllable periods.
