Over the last decades the phenomenon of co-transmission of two or more neurotransmitters from individual neurons has been firmly established. Our knowledge regarding mechanisms and purpose of co-release, however is only in its infancy. There is strong evidence, that in some cases co-transmission pattern of counteracting transmitters is activity dependent and that this plastic response pattern provides a crucially important protective mechanism against the consequences of overexcitation and excitotoxicity. To contribute to a better understanding of the underlying mechanisms of co-transmission we address the following questions in an invertebrate model system, the Central American wandering spider Cupiennius salei: (a) Which transmitters a co-released? (2) Which neuron populations co-release transmitters? (3) Does activity alter the neurochemical composition within these neurons? (4) Does activation alter electrophysiological response patterns and synaptic connectivity in central and/or peripheral pathways? In recent studies we have demonstrated that co-transmission is commonly observed in peripheral and central spider neurons. Currently we investigate the different combinations of transmitters that are co-released from individual neurons and test if the pattern of transmitter expression is activity dependent. Our hypothesis is that co-releasing neurons form a plastic network. We propose that neurons that constitute this plastic network regulate their transmitter content in an activity dependent manner and exert modulatory input on the main excitatory and inhibitory (static) pathways.

Ruth Fabian-Fine assistant professor of biology and neuroscience, and Will Mentor, associate professor of fine arts/art, co-curated an exhibition in the McCarthy Arts Center Gallery titled “Enhanced Vision: Artful Science from September 7 through October 13. This exhibition featured the often inaccessible aesthetic beauty of the natural world revealed through scientific research. It covers a broad spectrum from nature photography to the visualization of single molecules using modern research technology.

Ruth Fabian Fine, assistant professor of biology and neuroscience, recently was the recipient of a $25,000 Vermont Genetics Network (VGN) Pilot grant award; also, in recent months she helped set up and coordinate, with colleague Christina Chant, a new Scientific Imaging Facility on campus; Ruth also saw publication of a peer-reviewed paper with undergraduate student authors in the journal Cell and Tissue Research, titled “The Distribution of Cholinergic Neurons, and their Co-localization with FMRFamide in Central and Peripheral Neurons of the Spider Cupiennius salei (Ruth Fabian-Fine, Carly M. Anderson, Molly A. Roush, Jessica A.G. Johnson, Hongxia Liu, Andrew S. French and Päivi H. Torkkeli); she developed an outreach program in collaboration with Joan Wagner (director of community-engaged learning/coordinator of experiential learning), Rice High School and her Senior Seminar students to present for high school students on the cellular actions of venoms and toxins on the human body. During summer 2017 she is conducting summer research with five undergraduate students on campus.
