Mapping Carbon in the Amazon

August 8, 2019December 10, 2014 by Rebecca Maxwell

In order to produce the most detailed carbon maps of the Amazon, researchers turned to remote sensing, specifically satellite imagery and LiDAR.

The results demonstrated that the visual map of the tadpoles developed naturally when the bars moved from front to back. The tadpoles that were shown the images in reverse order, however, extended nerve fibers to the wrong spots in the map, confirming that the brain would perceive those images as backwards.
