Biological Psychology is the only branch that says that there is an underlying physiological cause for all our emotions, thoughts, and feelings. For example the release of oxytocin in females leads to bonding behavior and so on... As behavior is controlled by central nervous system, physicians are trying to understand how the brain works to different stimuli like sense, perception, and motivated behavior.

Educational Psychology deals with behavior of a person during learning process from a cognitive aspect. Educational psychology helps the teacher to understand the development of his pupils, the range and limits of their capacities of learning. Its works by incorporating other branches like Developmental Psychology, Behavioral Psychology and Cognitive Psychology.

Clinical Psychology is something that deals with the assessment of human abnormal behavior and its treatments.The common method of treatment for this type of abnormal behavior is Talk therapy or Psychotherapy which was first developed by Psychoanalyst Sigmund Freud; he was the first one who focused that mental illness can be treated with talking to the patients.

People go through so many physical and emotional changes over the course of their lives, while these changes are normal; developmental Psychology mainly focuses on studying these emotional, behavioral changes over their lifetime. These studies help in detecting abnormal changes and help to treat some of problems like depression, low self-esteem and others.

Applied Behavior Analysis is a type of treatment process which focuses mainly on improving specific behavior process. Unlike most of the therapies where they try to explain why and how the person behaves like they do, Applied Behavior analysis tries to replace bad with good; it uses positive reinforcement to bring that change. This method of therapy is mainly applied for autism patients.

Experimental Psychology involves the fact based aspects. It establishes the relationship between the activities of the brain and our behavior. Most of the experiments conducted in this area are done in Laboratory under controlled conditions .It also deals with hypothetical questions.

Experimental psychology explores basic concepts, such as memory and motivation, in many areas, such as child, social and educational psychology. Almost all Experimental psychology work is conducted in controlled environments, such as university research labs. While every branch of psychology strives to understand human behavior and thought, experimental psychology solely focuses on controlled experiments with designated variables, test subjects and statistical results.

Social psychology is a discipline that uses scientific methods "to understand and explain how the thoughts, feelings, and behavior of individuals are influenced by the actual, imagined, or implied presence of other human beings. Social psychology is all about understanding how each person's individual behavior is influenced by the social environment in which that behavior takes place.

Neurosurgery is a specialization that treats diseases and disorders of the brain and spinal cord. Back pain can sometimes produce neurological symptoms such as numbness, muscle weakness, due to improper coordination of nerves. These symptoms are indicators that neurosurgery is required to treat the conditions which cannot be treated by normal methods. Neurosurgery include discectomy, laminectomy, and spinal fusion surgery. Often there is a higher risk of nerve damage and infection which may result in paralysis.

Neurological disorders are diseases of the central and peripheral nervous system. In other words, the brain, spinal cord, cranial nerves, peripheral nerves, nerve roots, autonomic nervous system, neuromuscular junction, and muscles. These disorders include epilepsy, Alzheimer disease and other dementias, cerebrovascular diseases including stroke, migraine and other headache disorders, multiple sclerosis, Parkinson's disease, neuroinfections, brain tumours, traumatic disorders of the nervous system due to head trauma, and other neurological disorders as a result of malnutrition.

Clinical Neuroscience is a branch where it studies all mechanisms and changes during a brain or nervous system disorder, and it tries to develop new methods of treatment approach for these disorders,this branch of neuroscience is of more research oriented and experimental.

Cognitive neuroscience is the study of how the brain influences the mind. Cognitive science uses the experimental methods of cognitive psychology and artificial intelligence to create and test models of higher-level cognition such as thought and language.Cognitive Neuroscience acts as a bridge between brain and method.
