Evaluation of colonic motility in the guinea pig distal colon with the Gastrointestinal Motility Monitor (GIMM) is a straightforward and simple to learn approach to quantitatively evaluate propulsive motility in the gastrointestinal tract.

¹Vermont Genetics Network, The University of Vermont

In this protocol, gene expression in yeast (Saccharomyces cerevisiae) is changed after exposure to oxidative stress induced by the addition of hydrogen peroxide (H₂O₂), an oxidizing agent.

In Vivo Calcium Imaging of Taste-Induced Neural Responses in Adult Drosophila

Tynan Gacy¹, Molly Stanley¹

¹The University of Vermont

A calcium imaging approach enables the recording of taste-induced responses in the brains of awake flies while a solution is applied to the labellum. Primary gustatory responses in Drosophila melanogaster are used as an example, but this protocol can be adapted to study downstream neurons or other species.
