Final answer:
A neuroscientist is someone who views behavior as a result of complex chemical and biological events in the brain, incorporating interdisciplinary approaches to study the relationship between the nervous system and behavior.
Step-by-step explanation:
Someone who believes that behavior is the result of complex chemical and biological events within the brain is known as a neuroscientist. Neuroscientists explore the functions of the brain and the nervous system, working to understand how these biological systems relate to behavior, perception, and cognition. They often approach their work through an interdisciplinary lens that combines the research strategies of both psychologists and physiologists. Topics like sensory and motor systems, sleep, drug use, neurodevelopment, and biological correlates of psychological disorders fall within their purview, showcasing the diversity and complexity of this field.
