Understanding the Brain through Computational Models

Advertisment

At the intersection of biology, mathematics, physics, and artificial intelligence, lies an emerging field of neuroscience that is transforming our understanding of the brain. At the forefront of this exciting cross-disciplinary area is Kanaka Rajan, an associate professor of neurobiology at the Blavatnik Institute at Harvard Medical School and a founding faculty member of the Kempner Institute for the Study of Natural and Artificial Intelligence at Harvard University.

Rajan, a computational neuroscientist, specializes in building and manipulating models of the brain. She combines tools from mathematics, physics, and engineering, including artificial intelligence, to understand how animals and humans learn, remember, and make decisions. This pioneering work is shedding new light on the fundamental operating principles of the brain and is helping to identify the neural mechanisms responsible for complex cognitive processes.

The Power of Modeling the Brain

The advantage of building models of the brain, Rajan asserts, is that it allows researchers to access all the pieces of the brain and identify core operating principles. This approach provides a more comprehensive understanding of the brain than traditional experimental methods, which often focus on individual neurons or small groups of neurons. By using models, Rajan and her colleagues can examine the collective behavior of large groups of neurons and explore how they work together to drive learning, memory, and decision-making.

Studying Learning Trajectories and Social Groups

One of the key areas of Rajan's research is studying learning trajectories. By using brain models, Rajan can dissect the learning process into its basic components, much like learning math. This has helped provide insights into how different learning experiences can shape the brain and influence future learning.

Rajan's work also encompasses the neural mechanisms responsible for the emergence and stabilization of social groups. This research could have profound implications for understanding the neural basis of human social behavior and concepts like loneliness.

Making Computational Neuroscience Accessible

Beyond her research, Rajan is also passionate about making computational neuroscience accessible to a wider audience. She sees the potential of visual media to increase engagement and retention of scientific topics, especially among underserved high school students. Through her work, she hopes to inspire the next generation of scientists and encourage more diversity in the field of neuroscience.

As computational neuroscience continues to evolve, researchers like Rajan are leading the way in unlocking the mysteries of the brain. By combining disciplines and using new tools and techniques, they are not only advancing our knowledge of the brain but also opening up new opportunities for treating neurological disorders.
