ABSTRACT
We report a head-mountable CMOS camera for recording rapid neuronal activity in freely moving rodents using fluorescent activity reporters. This small, lightweight camera is capable of detecting small changes in light intensity (0.2% ΔI/I) at 500fps. The camera has a resolution of 32×32, sensitivity of 0.62V/lxs, conversion gain of 0.52µV/e(-) and well capacity of 2.1Me(-). The camera, containing intensity offset subtraction circuitry within the imaging chip, is part of a miniaturized epi-fluorescent microscope and represents a first generation, mobile scientific-grade, physiology imaging camera.
