Hey very cool! Well it’s not as perfect as it sounds but it will get better as it goes. If we had cultures of different kinds of brain cells, we could test some of the insecticides and other pesticides on specific types of cells. There still would be a lot of potential toxicity that could not be studied because of the complex interaction between the cells. But it’s a start, and in twenty years, if we could develope a model of the human brain itself, we could test some of these other higher level interactions as well.
