Transcardial injection of green algae or cyanobacteria in Xenopus laevis tadpoles distributed these photosynthetic microorganisms throughout the CNS causing a light exposure-timed increase of the oxygen concentration upon illumination of the brain; during a general, brain-wide extinction of neuronal activity by sub-atmospheric oxygen levels, green algae, and cyanobacteria were able to reversibly and repetitively reinitiate the spike activity upon illumination, thereby demonstrating the capacity of these microorganisms to rescue brain activity by photosynthetic oxygen.
