image: This image shows the head of a male German cockroach, showing the four major external chemosensory paired appendages. The antennae extend upward (black compound eyes behind them), the longer maxillary palps and shorter labial palps extend downward, and the paired paraglossae are on either side of the mouth. Each appendage contains many sensory hairs, some of which function in gustation. This image relates to a paper that appeared in the May 24, 2013, issue of Science, published by AAAS. The paper, by Ayako Wada-Katsumata at North Carolina State University in Raleigh, NC, and colleagues, was titled, "Changes in Taste Neurons Support the Emergence of an Adaptive Behavior in Cockroaches." view more
