Dear Brother / Sister,

8.1.3-The discovery that astounded scientists

Let us talk about a study published in National Geographic in 2014: They dissolved the fat in the brain of a rat with various chemicals. When the fat melted, a transparent brain remained. They gave another protein to the brain, which corresponded to one percent of the brain, revealing the large area where another neuron spread. A nerve cell circulated all over the brain, which is amazing. It is a serious discovery that a nerve cell circulated for several meters in the brain of the rat in 2014; it astounded scientists.
