About the field of Neurobiology: The general field of biology encompasses an extremely wide range of fields and specializations since all life can fall under this general category. As might be expected, neurobiology is the study of the body's nervous system. Many of the studies in neurobiology focus on the brain, but students also learn how the nervous system affects various functions such as behavior, states of consciousness and autonomic functions. The study of neurobiology can also be related to understanding and attempting to cure diseases, particularly those that affect the brain and nervous system. Related fields include: cancer biology , cellular/molecular biology , conservation biology , developmental biology , ecology , evolutionary biology , marine biology , microbiology/immunology , oral biology , structural biology , anatomy , anesthesiology , biochemistry , bioengineering , bioethics , biomedical sciences , biometrics or biostatistics , chemistry , clinical laboratory sciences , epidemiology , genetics , genetic counseling , health sciences , and human_development . Cancer biology can also provide a good foundation for those interested in becoming medical doctors or pursuing medical research . Some programs also tend to have a business application such as those in the biotechnology or medical informatics .
