insert those algal genes into the brains the way that you would put a gene uh into the brain uh is usually by using a virus um so this is uh a virus that that exists in nature but we have engineered it by removing everything that is pathogenic about the virus and then replacing those pathogenic genes with the gene that we're trying to put into the brain so in this case it's the gene from the green algae and by injecting the virus into a brain area that you want to study uh the virus will infect all the cells in that region and then make those cells begin to produce this ELO protein so once once the neuron starts to carry this ELO protein it becomes comes light sensitive so you can turn blue light on it and then be able to stimulate it
