The Dig Task: A Simple Scent Discrimination Reveals Deficits Following Frontal Brain Damage Kris M. Martens1, Cole Vonder Haar1, Blake A. Hutsell1, Michael R. Hoane1 1Department of Psychology, Southern Illinois University at Carbondale In this protocol, a novel application of scent discrimination is described. The Dig task is a reasonably inexpensive task that can be used to assess frontally-mediated cognition following brain damage.
Real-time Monitoring of Ligand-receptor Interactions with Fluorescence Resonance Energy Transfer Navneet Dogra1, Julia C. Reyes1, Nishi Garg1, Punit Kohli1 1Department of Chemistry and Biochemistry, Southern Illinois University We demonstrate FRET between conjugated polymer polydiacetylene (PDA) and fluorophore attached to the surface of PDA liposomes for the sensing of biomolecules. PDA liposomes also contained receptor molecules on their surfaces for biomolecules to be used as probes. Ligand-receptor interactions lead to changes in the FRET efficiency between the fluorophore and PDA which is the basis of the sensing mechanism.
