“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

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
