First, researchers created a gene which could be recombined in various arrangements to express one of four different colours. Then, multiple copies of this gene were inserted in the genome of mice or other species, resulting in the random expression of various colour ratios.

Central to neurodiversity is the idea that naturally occurring variations in the human brain should be seen as differences rather than deficits. Some people consider neurodiversity to be related to the concept of biodiversity — a term you will mostly see being used for the purpose of advocating for the conservation of species. 

Applied neuroscience explores the applications of neuroscience in real-world settings. Where most of the work in other neuroscientific branches is done in an academic setting, applied neuroscience is used by practitioners — professionals who work in clinics, hospitals, labs, schools, and companies — as a way to support their core discipline.

Due to the random nature in the expression of these genes, researchers are currently unable to precisely control the labeling process, which makes it very hard to identify specific neurons. They get a good idea of what the circuit looks like, but not exactly which class of cells each neuron belongs to.
