NSCI 175 Exam 1 Study Guide with correct answers

Explain why progress in science is often slow Answer Science is an ongoing process of questioning, observing, and testing Explain the reductionist approach Answer Neuroscientists break down complex problems into smaller pieces for systematic experimental analysis Compare the levels of analysis: molecular, cellular, systems, behavioral, and cognitive neuroscience Answer Molecular Neuroscience: Brain matter consists of molecules and these different molecules play many different roles crucial for brain function. Focus on single proteins/molecules and its function. Cellular Neuroscience: Focus on studying how all these molecules work together to give neurons their special properties. "How many different types? How do they differ in function? How do they wire together?" Systems Neuroscience: Study how different neural circuits analyze sensory information, form perceptions (from external world), make decisions, and execute movements. Focus on distinct circuitry. Behavioral Neuroscience: Study on how these neural systems work together to produce integrated behavior. Drugs and regulation of mood and behavior; memory in different systems; systems and gender-specific behavior. Cognitive Neuroscience: Understanding neural mechanisms responsible for higher levels of human mental activity, such as self-awareness, imagination, and language.
