They found that dominant and subordinate crayfish differ in their behavioral responses when touched unexpectedly, and that those differences correlate with differences in neural circuits that mediate those responses.
The article was published this week in the Journal of Neuroscience. The research team included Edwards, Fadi A. Issa and Joanne Drummond of Georgia State, and Daniel Cattaert of the Centre de Neurosciences Integratives et Cognitives of the Universities of Bordeaux 1 and 2.
When dominant crayfish are touched unexpectedly, they tend to raise their claws, while subordinate animals drop in place and scoot backwards, said Donald Edwards, Regents' Professor of neuroscience at Georgia State.
In looking at the nervous systems of the animals, the researchers noticed differences in how neurons were excited to produce different reactions to being touched when the animals' behavioral status changed. The changes do not represent a wholesale rewiring of the circuits, Edwards said.
"There is reconfiguration going on, but it is probably a shift in the excitation of the different neurons," he explained.
Neuroscientists at Georgia State are working on building computational models of the animals' nervous systems to learn more about how the neurons work in crayfish.
"If you can't build it, you don't know truly how it works," Edwards said.
The research appears in "Neural Circuit Reconfiguration by Social Status," Journal of Neuroscience, 32(16):5638-5645.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
