University of Oregon, on behalf of CAS Human Physiology, (University), intends to purchase a nVue 2.0 System for Dual Color In Vivo Imaging A dual-color imaging platform and Inscopix Communitator System to be used for dual color calclum imaging in freely behaving rodents. This purchase will allow the study of the cellular physiology of respiratory neuron populations, particularly the respiratory motor neurons. University research requires equipment that can be used to gain detail about physiological function at the cellular and molecular without destroying the neurons during the tissue slicing processes. The University requires the ability for dualcolor imaging capability, modularity, high speed video capture, and high-resolution, other unique features, such as its electronic focus integration and direct behavioral synchronization capabilities, are not available from any other vendor.
