Abstract: Disclosed herein are electrically conductive polymer compositions comprising a polymer and a dispersant, and methods of synthesizing the polymers therein. Also disclosed herein are microelectrode arrays comprising the electrically conductive material and a conductive polymer composition attached to a surface of the electrically conductive material. Further disclosed herein are methods of detecting electrical activity in a cell comprising contacting the microelectrode array with a cell and detecting electrical activity in the cell by covalently attaching the polymer of the conductive polymer composition to a protein on the surface of the cell.

Abstract: An observation chamber for three-dimensional kinematic profiling of subject animals. One example system for analyzing free-moving animal subject behavior includes a housing, a transparent arena configured to hold a subject, a camera mounted below the arena, and a mirror system configured to reflect multiple images of the subject in a single field of view of the camera. A height of the housing is less than 80 inches, and a width of the housing is less than 32 inches. The system fits within standard doorway dimensions.
