How do Neuroscience, Neurobiology compare side by side?
The table below compares Neuroscience, Neurobiology across 13 procurement-relevant dimensions, from definition through when to use which term.
Side-by-side comparison
| Dimension | Neuroscience | Neurobiology |
|---|---|---|
| Definition | The scientific study of the nervous system, the brain, spinal cord and neural networks, and of how it produces perception, movement, thought, emotion, memory and behavior. | The branch of biology that studies the nervous system at every level of organization, from molecules inside a neuron to the circuits that produce behavior, cognition and disease. |
| Relationship between the two | The broader, more interdisciplinary umbrella field. It is described as a branch of biology that also draws on chemistry, physics, psychology, computer science and medicine. | Sits at the biological core of neuroscience. It is the biological, mechanistic study of the nervous system within the wider field. |
| Interchangeable? | Often used as the general name for the whole field, including where others would say neurobiology. | Frequently used interchangeably with neuroscience, particularly in department names, degree titles and graduate programs. |
| Emphasis | Connecting biological mechanism to behavior, cognition and disease, so it includes work that starts from behavior or computation as well as from cells. | How nerve cells are built, how they generate and transmit electrical and chemical signals, how they wire up during development and how they fail in disease. |
| Levels of analysis | Molecular and cellular, circuit and systems, behavioral and cognitive, and clinical levels. | Spans ion channels and synapses, single neurons and glia, local circuits and whole-brain systems, with a strong mechanistic and cellular-molecular center of gravity. |
| Typical subfields | Molecular and cellular, systems, cognitive, behavioral, developmental, computational, clinical or translational, neuroimmunology, social and affective, and comparative neuroscience. | Cellular and molecular, developmental, systems and circuit, behavioral, neuroendocrinology, neuroimmunology, neurodegeneration mechanisms and computational neurobiology. |
| Methods in general terms | Electrophysiology, neuroimaging (MRI, PET, MEG, EEG), optogenetics, calcium imaging, connectomics, genetic tools, animal models, computational modeling and human neuropsychological testing. | Electrophysiology, optical imaging, optogenetics and chemogenetics, molecular and genetic tools such as single-cell sequencing and gene editing, anatomical and connectivity methods, behavioral assays and computational analysis. |
| Research oversight | Work with vertebrate animals is reviewed by an institutional animal care committee (in the US, an IACUC), and work with human participants by an ethics board (in the US, an IRB). Human imaging and cognitive testing are common. | The same oversight applies. Animal models such as rodents are common in the cellular, circuit and developmental work typical of the field, and human tissue or imaging work needs the relevant human-subjects review. |
| Typical work | Studying how circuits give rise to cognition or behavior, imaging human brain activity, modeling neural systems, and research aimed at neurological and psychiatric disease. | Recording from and manipulating neurons, characterizing proteins and genes in neurons and glia, tracing development and wiring, and studying mechanisms of neurodegeneration. |
| Training | Research careers typically run through a PhD in neuroscience, neurobiology or a related field; some researchers enter from psychology, biology, bioengineering or physics. MD/PhD for clinically oriented tracks. | Typically a PhD in neuroscience, neurobiology or a closely related biological science such as cell biology, molecular biology or physiology, then postdoctoral training. MD or MD/PhD for physician-scientists. |
| Funders (US) | NIH, through several institutes (NINDS, NIMH, NIA, NIDA, NIAAA, NICHD), plus NSF, the BRAIN Initiative and private foundations such as Simons, Kavli, HHMI and Dana. | Predominantly NIH (NINDS, NIMH, NIA, NIDA, NIAAA, NICHD), NSF basic research through its Directorate for Biological Sciences, the BRAIN Initiative, and foundations such as HHMI. |
| Societies and careers | The Society for Neuroscience (SfN) is the field’s largest professional society; subfield societies include the Cognitive Neuroscience Society. Careers in academia, pharma and biotech R&D, devices, data science and science policy. | SfN is also the principal society for neurobiologists, alongside more specialized subfield societies. Careers in academia, pharmaceutical and biotechnology drug development, science policy and scientific communication. |
| When to use which term | Naming the whole field, a program that spans biology, cognition and computation, or work that links brain and behavior. | Stressing the biological, cellular and molecular mechanisms of the nervous system, or following a department or lab that uses that name. |
Common questions
Common questions about Neuroscience vs Neurobiology
Is neurobiology the same as neuroscience?
+
The terms overlap substantially and are often used interchangeably. Where a distinction is drawn, neurobiology usually refers more specifically to the biological, cellular and molecular study of the nervous system, while neuroscience is the broader interdisciplinary field that also encompasses cognitive, behavioral, computational and clinical approaches.
Is neurobiology a part of neuroscience?
+
Generally yes. Neurobiology is described as sitting at the biological core of neuroscience, which acts as an umbrella over its cellular and molecular focus alongside cognitive, behavioral, computational and clinical work.
Do I need different degrees for neuroscience and neurobiology?
+
Usually not. Research careers in either typically require a PhD in neuroscience, neurobiology or a closely related biological science, followed by postdoctoral training for independent academic positions. Many programs are broad and let students rotate through several labs before choosing a dissertation focus, so check the individual program rather than the label.
Which NIH institutes fund this research?
+
Funding is spread across several institutes depending on the question. NINDS is the institute most directly focused on the nervous system and its disorders, alongside NIMH, NIA, NIDA, NIAAA and NICHD, and cross-institute efforts such as the BRAIN Initiative. At NSF, basic research is funded mainly through the Directorate for Biological Sciences.
How do neuroscience and neurobiology differ from neurology?
+
Neurology is a clinical medical specialty that diagnoses and treats diseases of the nervous system in patients. Neuroscience and neurobiology are research disciplines; a neurologist may or may not also do research, and many researchers are not physicians. See the separate comparison of neurology and neuroscience.
How do they differ from psychology?
+
Psychology studies behavior and mental processes broadly, without requiring an account of the underlying brain mechanism. Neuroscience, and neurobiology in particular, study the nervous system itself; cognitive and behavioral neuroscience share psychology’s questions but ground the answer in neural structure and activity.
Which term should I use on a CV, program application or grant?
+
Follow the language of the department, program or funder you are addressing, since the labels are largely interchangeable. If you want to emphasize cellular and molecular mechanisms, neurobiology is a natural fit; if your work spans levels or disciplines, neuroscience is the more general term.
