<\/p>\nIt\u2019s just about that time of year again \u2013 in just over a week\u2019s time we\u2019ll be sitting down to a huge feast consisting of turkey, stuffing, and mashed potatoes; we\u2019ll be watching the Macy\u2019s Parade soon to be followed by two football games; and we\u2019ll be giving thanks for our reunion with our grandparents, uncles, aunts, cousins, brothers, sisters, parents, and more. Thanksgiving definitely holds a special place in my heart \u2013 however, up until recently, it always used to provide just a little bit of stress. That is because, at least in my family, somewhere between polishing off the last roll and preparing for pecan pie one relative or another always asks me, \u201cso what are you studying in school again?\u201d And when I answer \u201cNeuroscience!\u201d I typically get one of two responses: the confused look, followed by \u201cNeuroscience? What is<\/i> neuroscience?\u201d (typically from the older crowd in the room), or the rolling of the eyes, followed by \u201cWhat are you going to do with a degree in neuroscience<\/i>?\u201d (typically from the former engineers and business majors). I love neuroscience, and I know I\u2019ve found my passion studying it here at BU, but those questions always seem to bring with them a certain pressure that I always felt I cracked beneath. However, I recently discovered the perfect way to address both of these questions, and I\u2019m here to let you in on the secret so you can impress your relatives at the thanksgiving dinner table as well. This year, when Grandma or Uncle Tony ask me \u201cwhy neuroscience?\u201d my answer will be simple \u2013 because neuroscience is changing, and will continue to change, the world and how we approach it. <\/p>\n
I can already imagine the taken aback look crossing my relative\u2019s faces, and the comment that I\u2019m perhaps being a little dramatic \u2013 neuroscience is changing the world<\/i>? Not only will my answer definitely get their attention, but I\u2019m confident that my answer is correct, and proving my point to my disbelieving family will only make Thanksgiving that much more fun. Neuroscience is the science of understanding the nervous system (that is the system that essentially allows for all of our functioning) on a basic scientific level, and then applying that knowledge to do a bunch of things, from eradicating the diseases that plague the system (Alzheimer\u2019s, Parkinson\u2019s), to applying the knowledge in the classroom so that students of all ages can learn to their full potential. If you take a step back and view the whole picture, it\u2019s not surprising that neuroscience will change the world in our lifetime; as opposed to some other fields, neuroscience is constantly acquiring completely new information about systems that not too long ago used to be a complete mystery \u2013 this knowledge is overflowing and already being applied to the real world to make beneficial changes. I will quickly outline two fascinating new outlets of neuroscience that are changing the world right before our very eyes, so that you have solid proof to further widen the eyes of your relatives this holiday season.<\/p>\n

Optogenetics is perhaps my favorite thing to talk about, and though it is so new my Microsoft Word 2010 believes I\u2019ve spelled something wrong, it is already changing the world. Optogenetics is complex, probably too complex for most people without a science background to fully understand, but don\u2019t fear! Simply explaining the basics is enough to turn anybody into a neuroscience fan. Optogenetics is the science of inserting light activated channels into neurons to elicit a certain response. The mechanisms as to how this is achieved are too complex to understand at the dinner table, but the main idea is this. Neuroscientists have the ability to genetically insert\u00a0certain channels that can either elicit an excitatory or inhibitory response in a select population of neurons. These channels are activated by light, so once stimulated with light the channels either open or close \u2013 allowing for an action potential to be sent, or inhibiting one. This concept can theoretically be applied to so many pathologies \u2013 from inhibiting the overactive neurons associated with schizophrenia, to activating damaged hair cells in the cochlea that can\u2019t transmit signals to the auditory cortex. In the lab, this science has already been shown to immediately produce movement in mice when neurons are activated in the motor cortex, and help blind mice sense light when activated in the bipolar cells of the retina. Optogenetics is SO cool and will change the world for the better.<\/p>\n
Another application of neuroscience in the real world is neuroscience in the classroom. As advances have been made in understanding the complex neural processes of learning and memory, it\u2019s become obvious that perhaps the traditional way of teaching needs to be rethought as well. Perhaps traditional lectures with no chance for collaboration should be replaced with an environment that fosters question asking and group work. This concept is already being applied right here at BU, with some physics classes being set up in a studio section. The ultimate goal is to have all physics classes taught in this manner. Neuroscience factored into the research that determined new learning environments foster better learning among students. Neuroscience also helps us to understand that different students have different brains and therefore learn best in different ways; accounting for this can help teachers create a more effective learning environment for all their students. This is yet another example of neuroscience\u2019s promise to change fundamental parts of society, like lecture style college classes that have been traditional for generations.<\/p>\n
I don\u2019t know if it\u2019s obvious, but I\u2019m definitely extra excited for Thanksgiving this year \u2013 I can\u2019t wait to finally live up to the pressure of the \u201cwhy neuroscience\u201d question, and exceed everyone\u2019s expectations with my bold yet absolutely valid response. Needless to say, my Thanksgiving will definitely have a healthy helping of neuroscience to go with it \u2013 my new favorite side dish.<\/p>\n
