Optogenetics is a more and more recognized technique for investigating neuronal populations in the rodent brain. Combined to fMRI (OfMRI), more understanding could be achieved. However, the effects of powerful light on the tissue remain poorly understood. Here, experiments were conducted to investigate the effects of blue laser light on the metabolism of the primary somatosensory cortex.
