Explore the intricate workings of the human brain, from neurons and glia to the central and peripheral nervous systems. Learn how sensory input, emotions, and memories shape our decisions and actions.

Scientists and engineers from Caltech and elsewhere have advanced our understanding of how the brain and nervous system work, but much remains a mystery. Learn the primary parts of the brain, how neurons work, and where emotions and consciousness come from.

The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.

Jan 27, 2025 · Hong’s work might sound like science fiction. But he and other Wu Tsai Neuro researchers all share a clear, attainable vision for the future – one where the brain can be more easily studied ...

Sep 29, 2021 · The brain works like a big computer. It processes information that it receives from the senses and body, and sends messages back to the body. But the brain can do much more than a machine can: We think and experience emotions with our brain, and it …

Scientists do not know and have no theories explaining how brains and central nervous systems work. The usual explanations are that scientists lack methods, techniques, and efficient data analysis to obtain this goal.

Learn how scientists study the brain using cutting-edge tools and techniques, from optogenetics and fMRI to model organisms like mice, zebrafish, and fruit flies. Explore the fascinating world of neuroscience research.

The brain inspires novel conceptual paradigms and innovative technologies and designs that advance science and engineering to benefit society. Flexible, self-organizing, and energy- and data-efficient, the brain continues to be a source of inspiration for future technologies and discovery of scientific principles.

Whether you are navigating unfamiliar terrain or reacting to a sudden threat, your brain processes and acts on new information rapidly. Neurons continuously adjust their coordination, keeping the brain stable enough for deep thought, yet agile enough to respond to new challenges.
