“Let There Be Light” Before, the intricacies of the brain remained a mystery despite the advancing technology. However, now, scientists have created light responsive molecules that are injected into the neurons of an animal. This allows the scientist to understand the brain cells activity. This science is now called optogenetics which is where scientists can control the neurons in animals. This light technology has given new light as to the cause of depression, addiction, or even schizophrenia. This has also allowed scientists to obtain a better understanding of the brain and nervous system. As scientist Karl Diesseroth state that the point of optogenetics is to “get to the neural code for complex things, such as reward.” In science, such a thing of causality, for example the causes of a disease, are very important to study. This new branch of technology have given causality to neuroscience in that it elucidates the causes of many neurological conditions. To figure out how neurons act is a simple process of “flipping it on or off.” This is on when a specific wavelength of light is shined on the light responsive molecules and the channel opens to allows positively charges ions to move in and out of the cell. A different wavelength would allow negatively charged ions to move in and out of the cell. The main difference between
