The Brain Unfolds Like a Drama, With Neurons in Different Roles

Researchers studying fruit flies hope that spotting the stages at which human neurons go missing or wrong can help develop treatments to insert or replace them

We are not accustomed to thinking of fruit flies as even having brains. But they have 120 types of neurons in their visual system alone (which could be why they are so pesky): In the research published in Nature, the researchers studied the brains of the fruit fly Drosophila to uncover the complete set of tTFs needed to generate the roughly 120 neuron types of the medulla, a specific brain structure in the visual system of flies. They used state-of-the-art single-cell mRNA sequencing to obtain the transcriptome — all of the genes expressed in a given cell — of more than 50,000 individual cells that were then grouped into most of the cell types present in the developing medulla… The…
