Neuroscience examines the nervous system across molecular, cellular, circuit, systems, cognitive, behavioral, and clinical levels.
Neuroscience is the scientific study of the nervous system, including the brain, spinal cord, peripheral nerves, their functions, development, disorders, and capacity for change. Its scope extends across multiple levels of analysis, from molecules, genes, and individual neurons to neural circuits, brain systems, cognition, behavior, and consciousness. Modern neuroscience uses techniques such as microscopy, electrophysiology, genetics, neuroimaging, computational modeling, and brain stimulation to investigate how the nervous system is structured and how it produces perception, learning, memory, emotion, movement, and decision-making. Neuroscience is inherently interdisciplinary, integrating anatomy, physiology, molecular and cellular biology, developmental biology, psychology, chemistry, physics, mathematics, statistics, computer science, and medicine. Its subfields include molecular and cellular neuroscience, systems and computational neuroscience, cognitive and behavioral neuroscience, neuroendocrinology, neuroimmunology, neuroethology, and clinical neuroscience. These connections have also produced applied fields such as neuroeconomics, neuroeducation, neuroethics, neurolaw, neural engineering, and neuromorphic computing, while medical specialties such as neurology, psychiatry, neurosurgery, and neuroradiology apply neuroscientific knowledge to nervous-system disorders.
Neuroscience examines the nervous system across molecular, cellular, circuit, systems, cognitive, behavioral, and clinical levels.
It combines methods and concepts from biology, medicine, psychology, chemistry, physics, mathematics, statistics, and computer science.
Its broad scope includes both basic questions about neural structure and function and applied areas such as clinical treatment, neurotechnology, neuroethics, and brain-inspired computing.
Major research topics include neuronal signaling, synaptic communication, neural development, brain organization, neuroplasticity, cognition, emotion, learning, memory, and neurological and psychiatric disorders.
The multidisciplinary scientific study of the nervous system, its functions, development, disorders, and interactions with behavior and cognition.
The study of the molecular mechanisms, cellular properties, development, and signaling processes of neurons and glial cells.
The investigation of how neural circuits and large-scale brain networks produce sensory, motor, emotional, and cognitive functions.
The study of how neural circuits and brain systems generate psychological processes such as perception, attention, memory, language, and decision-making.
The use of mathematical models, theoretical analysis, and computer simulations to explain the behavior of neurons and neural networks.
The application of neuroscience to the diagnosis, understanding, prevention, and treatment of nervous-system and brain-related disorders.
The capacity of the nervous system to change its structure and function in response to development, experience, learning, injury, or environmental demands.
