For the first time, scientists have mapped the structure of mitochondria, a key structure of the human brain, a feat that could help unravel the mystery of age-related brain diseases. On 260, the relevant research results were published in Nature.

The findings suggest that the mitochondria, which provide energy to cells, vary in type and density in different parts of the brain. For example, the oldest brain regions during evolution have lower mitochondrial densities than newer regions. Valentin Riedl, a neurobiologist at the University of Erlangen-Nuremberg in Germany, said the structural map, which the researchers called the "mitochondrial brain map," was "technically impressive and conceptually groundbreaking."

Different areas of the human brain (artificially colored) have different densities of mitochondria
