A Journey into the nervous system CtY neuroscience L 12 imagine by Carli Huber ast January, for the fifth consecutive winter, I pored over a CTY course catalog to find my next summer class. I knew I wanted to continue my pursuit of biology and chemistry, but I had discovered some things about myself over the years. For example, I realized that I don’t enjoy studying large-scale biology, such as entire ecosystems. Instead, I’m drawn to the microscopic world of biology, where the chemistry involved is especially complex. And in addition to the natural sciences, I had developed an interest in psychology. As I looked through the catalog, I was excited to see a course that combined all my interests: Neuroscience. I learned that nerve cells, or neurons, communicate with one another by a complex process that involves both electrical and chemical signals. Neurons are known as “excitable” cells because when they are stimulated (chemically, electrically, or mechanically), they generate an electrical impulse that spreads throughout the entire cell. When the impulse reaches the end of the cell, it causes the cell to release a chemical called a neurotransmitter, which can chemically excite nearby neurons. The neurotransmitter released by one neuron can trigger an impulse in the Molecular Foundations In June, I arrived at Dickinson College in Carlisle, Pennsylvania, ready for my latest CTY session. As usual, the dorms, activities, and meals were fantastic, but neuroscience was my focus, and I was instantly obsessed. Neuroscience can be studied at the molecular level, at the cellular level, in the structure of the brain as a whole, and from a psychological perspective. I soon discovered that understanding neuroscience at any level required explicit knowledge of the molecular chemistry involved. sept/oct 2012 ThinksTock,
