Professor Jeff Lichtman, Head Tutor
Neurobiology, the study of the nervous system, is a field of science that investigates the biological mechanisms that underlie behavior as well as how brains process information. To develop a comprehensive understanding, we study the nervous system at every level from the macroscopic (behavior and cognition) to the microscopic (cells and molecules). Consequently, the questions that neurobiologists ask are wide-ranging. For example, how do electrical, chemical, and molecular signals allow neurons to process and transmit information from the environment? What guides the development of the immense number of precise connections in the nervous system? How can the complex signals of many thousands of active neurons be recorded, interpreted, and modeled? What causes the profound behavioral deficits in Alzheimer’s disease or Autism Spectrum Disorders?
To answer these kinds of questions, neurobiologists study a variety of model systems including cultured cells, fruit flies, zebrafish, mice, monkeys, and even humans. Simpler systems allow experimental manipulations (e.g., gene knockouts/knockins, protein over/mis-expression, drug treatments, activity silencing) and invasive recording techniques (e.g., fluorescently labeling cells and proteins, electrically/optically recording neurons and networks, electron microscopy of the synapses and circuits). Studies in humans often focus on characterizing patterns of brain activity during development or disease using non-invasive recording techniques (e.g., fMRI and EEG). Neurobiologists may also use approaches from computer science and mathematics to analyze signals that arise from the brain or to understand the computational properties of neural networks. Thus, the study of neurobiology provides both a broad scientific training and a deep understanding of the biology of the nervous system. Given the diversity of interests in this field, the only prerequisite for students entering this concentration is an intense curiosity about the brain.
The Neurobiology curriculum includes a series of fundamental courses in the life and applied sciences. A central course on the neurobiology of behavior, Molecular and Cellular Biology (MCB) 80 or 81, lays out the body of knowledge in neurobiology. In advanced elective courses, students explore specific areas of neurobiology more deeply based on their interests. We now list over 40 advanced courses on a range of topics: cells and circuits, physiology, learning and memory, cognitive science, development, genetics, computational modeling, and disease and therapeutics. In addition to the course offerings, neurobiology is one of the most vibrant fields of research at Harvard, and students will have many opportunities for hands-on laboratory experience and independent research projects to complement and deepen their studies.
We offer three tracks within the Neurobiology concentration. The first, the ‘Neurobiology Track’, provides the greatest focus on biology and neurobiology coursework and ensures a solid foundation in the life and physical sciences. For this track, Honors is optional. The second track, the ‘Mind, Brain, and Behavior Track’, allows students to look beyond the biology of the brain and see how other disciplines (e.g., anthropology, economics, computer science, history of science, linguistics, philosophy, and psychology) approach the study of the mind. This is an Honors track and requires an undergraduate thesis. The third track, the ‘Computational Neuroscience Track’, allows students to develop skills in mathematics and computer science to analyze and model the signals of the brain. For this track, Honors is optional.
