This article talks about Connectomics, which is considered a branch of biotechnology that uses automated, high-speed imaging systems to construct detailed maps of neural circuits. It is the study of the structural and functional connections among brain cells; its product is the “connectome,” a detailed map of those connections. Efforts to construct brain connectomes are split into two categories: ones that use imaging techniques like MRI, PET, and DT, thus focusing on macroscopic connections or tracts.
