Singapore scientists have carried out a major breakthrough in a “tiny brain” studies. This tiny version of the human brain will help researchers develop treatments and research on Parkinson’s disease and brain disorders associated with age. Miniature brains are three-dimensional tissues grown in the laboratory and have certain properties of specific parts of the human brain. For the first time in the organic model black pigment neuromelanin has been found. The study also revealed functionally active dopaminergic neurons.
