How do Neuroscience, Psychology compare side by side?
The table below compares Neuroscience, Psychology across 12 procurement-relevant dimensions, from core definition through when to use which.
Side-by-side comparison
| Dimension | Neuroscience | Psychology |
|---|---|---|
| Core definition | The scientific study of the nervous system (brain, spinal cord and the networks of neurons that extend through the body) and of how it produces perception, movement, thought, emotion, memory and behavior. It is a branch of biology that is heavily interdisciplinary. | The scientific study of mind and behavior: how people and other animals think, feel, perceive, learn, develop and interact. It sits at the intersection of biology and the social sciences, and in its applied branches is also a health profession. |
| Central question | What physical structures and activity in the nervous system produce a given function, behavior or disorder, and how do they develop and change? | What does a behavior or mental process look like, what causes it, and can it be predicted or changed by an intervention such as a therapy, training program or policy? |
| Level of analysis | Nested levels from molecular and cellular, to circuits and systems, to behavioral and cognitive, to clinical. The distinctive commitment is explaining the upper levels in terms of the lower ones. | Mostly the whole organism: individual behavior, cognition, emotion and social context. Modern research is often biopsychosocial, treating behavior as jointly produced by biological, psychological and social factors. |
| Characteristic methods | Electrophysiology, neuroimaging, optogenetics and chemogenetics, calcium imaging, connectomics and tract tracing, transgenic and gene-editing tools, and computational modeling. | Controlled behavioral experiments, systematic observation, surveys and validated measurement (psychometrics), longitudinal and developmental designs, clinical trials of interventions, and statistical modeling. |
| Typical tools | Patch-clamp and multi-electrode recording, EEG, fMRI, PET and MEG, microscopes with fluorescent activity indicators, viral vectors and CRISPR, and large-scale data analysis pipelines. | Experiment-presentation software, questionnaires and standardized tests, eye tracking, reaction-time and behavioral coding, and statistical software. EEG and fMRI are also widely used, especially in cognitive and biological psychology. |
| Animal vs human research | Both. Rodents are the dominant mammalian model, with C. elegans, Drosophila and zebrafish widely used for conserved mechanisms. Human work relies mostly on non-invasive imaging and recording, and on patients with brain damage. | Mostly human participants, from infants to older adults, with animal research concentrated in behavioral and biological psychology, such as learning and comparative studies. Direct invasive manipulation of the nervous system is rare in human work. |
| Typical work | Running experiments on neural circuits or cells, building tools to record or manipulate neural activity, analyzing imaging and recording data, computational modeling, and translational work on neurological and psychiatric disease. | Designing and running behavioral studies, developing and validating measures, delivering and evaluating therapies (clinical and counseling), and applying findings in schools, workplaces, health and legal settings. |
| Training and credentials | Usually a bachelor's degree in neuroscience or a related science (biology, chemistry, psychology, computer science), then a doctoral degree. Many neuroscientists enter from other disciplines. | A bachelor's in psychology, then a doctorate for research and clinical practice (a Ph.D., or a Psy.D. for practice-focused clinical roles). Clinical practice requires licensure, which varies by jurisdiction. |
| Funders (US) | NIH funds the most, mainly through NINDS and also NIMH, NIA, NIDA, NIAAA and NICHD, plus the NIH-led BRAIN Initiative. NSF's Directorate for Biological Sciences funds basic work. Simons, Kavli, HHMI and the Dana Foundation are significant private funders. | NIH, mainly NIMH (with NICHD, NIA, NIDA and NIAAA, and the OBSSR coordinating office). NSF funds psychology as basic science through the Division of Behavioral and Cognitive Sciences. The American Psychological Foundation is a private funder. |
| Careers | Academic research, pharmaceutical and biotechnology research, neurotechnology, computational and data roles, and research support in medical centers. Clinical care of nervous-system disorders is the work of neurology, a separate medical specialty. | Clinical, counseling, school, industrial-organizational, health and forensic practice, academic research and teaching, user and market research, and psychometrics. Psychiatry, which can prescribe, is a separate medical specialty. |
| Where they overlap | Cognitive and behavioral neuroscience ask psychology's questions but insist on grounding the answer in brain structure and function. Social and affective neuroscience and developmental cognitive neuroscience are common working combinations. | Biological (physiological) psychology and cognitive psychology sit at neuroscience's behavioral end and increasingly use neuroimaging and genetics, so the two literatures, funders and journals overlap. |
| When to use which | Use it when you need a mechanism: which cells, circuits or molecules explain a function or a disease, and how to manipulate them. | Use it when you need to describe, measure or change behavior and mental states in people, or to design and evaluate an intervention. |
Common questions
Common questions about Neuroscience vs Psychology
What is the main difference between neuroscience and psychology?
+
Neuroscience studies the nervous system at every level, from molecules and cells to circuits and whole-brain systems, and tries to explain behavior and disease in terms of neural structure and activity. Psychology studies mind and behavior, mostly at the level of the whole person, and does not require a neural explanation. The fields overlap substantially, so the difference is mainly one of level of analysis and method.
Is psychology a branch of neuroscience, or the other way around?
+
Neither. They are distinct disciplines with a large shared area. Neuroscience is a branch of biology, while psychology spans biology and the social sciences and includes applied clinical practice. Cognitive neuroscience, behavioral neuroscience and biological psychology sit in the overlap and are claimed by both.
What is cognitive neuroscience, and which field does it belong to?
+
Cognitive neuroscience studies the neural basis of higher mental functions such as attention, memory, language and decision-making, often in humans using non-invasive imaging. It belongs to both fields. NSF, for example, lists a Cognitive Neuroscience program within its Division of Behavioral and Cognitive Sciences, and NIH funds the same work through several institutes.
Should I study neuroscience or psychology?
+
Neuroscience suits you if you want to work on biological mechanisms, laboratory methods, animal models or neural data. Psychology suits you if you are drawn to behavior, measurement, human development or clinical and applied work, and it is the usual route to becoming a licensed psychologist. Many programs let you combine them, so check the actual curriculum and research opportunities rather than the department name.
Is neuroscience harder than psychology?
+
Neither is simply harder; they ask for different skills. Neuroscience typically involves more biology, chemistry, physics and computation, and laboratory technique. Psychology typically involves more experimental design, measurement theory and statistics, and, in clinical routes, supervised practice. Both require statistics and research design.
Can a psychologist prescribe medication or treat brain disease like a neurologist?
+
In most US states a psychologist cannot prescribe medication, and diagnosing and treating disorders of the nervous system is the work of medical specialties: neurology for neurological disorders and psychiatry for mental disorders. Psychologists provide assessment and psychotherapy. See the comparisons of neurology and neuroscience and of psychology and psychiatry for these boundaries. This page is not medical advice.
Which gets more research funding, neuroscience or psychology?
+
This page does not claim a ranking, because the two portfolios overlap and funding is spread across many agencies and programs. In the US, NIH is the largest funder of both, with NINDS most focused on the nervous system and NIMH most central to psychological research. NSF funds both as basic science through different directorates.
