Imagine all the stars in the universe. The brain has a thousand times the number of synapses, making neurological errors a near certainty. I learned this fact firsthand as a 14 year-old, when I suffered from sleepless nights because of an uncomfortable, indescribable feeling in my leg. It took months of appointments and tests to be told it was a condition called cortical dysplasia. Even after the diagnosis, there is no cure.

I am lucky. My condition does not severely affect my quality of life. However, I know this is not the case for everyone. After this experience, I took Advanced Program in Biology and attended a neuroscience program, which reinforced the subject as my future calling. One of the most impactful lectures discussed the plight of healthcare in developing nations. Newborns with extreme neurological deficits are common, but finding treatments is not. Without prenatal care, this is becoming a growing epidemic, leaving millions of children helpless. 

With a degree in neuroscience, I will gain a strong understanding of neural tube development and neuronal migration in infants. I will then become a neurologist, specializing in pediatric care. I hope to work for humanitarian organizations, such as Doctors Without Borders, in Africa, where HIV and polio are rampant, as are numerous other diseases. 

Imagine the stars once more. From across the world, I will look at the same stars in the future, as I help children secure the ability to not only look at the stars, but do much more.
