Review Questions

• How do non-human primates contribute to our understanding of cognition and behavior?
  • Non-human primates play a crucial role in enhancing our understanding of cognition and behavior due to their cognitive capabilities and social structures. By studying their problem-solving skills and social interactions, researchers can draw parallels with human cognition. This helps uncover the evolutionary origins of certain cognitive processes and behaviors that are shared between humans and non-human primates.
• What are some ethical concerns associated with using non-human primates in neuroscience research?
  • The use of non-human primates in neuroscience research raises significant ethical concerns regarding their welfare, including the potential for distress or harm during experiments. Researchers must navigate complex ethical guidelines to ensure humane treatment. This includes considerations for housing, social grouping, and minimizing invasive procedures while maximizing scientific knowledge gained from these studies.
• Evaluate the impact of optogenetics and chemogenetics on research involving non-human primates in understanding neurological functions.
  • Optogenetics and chemogenetics have revolutionized research involving non-human primates by providing precise tools for manipulating neural activity. This enables scientists to observe immediate behavioral changes linked to specific neural pathways, offering deeper insights into neurological functions. The ability to control neuronal activity in real time allows for advanced studies into complex brain functions, significantly enhancing our understanding of both normal behavior and neurological disorders.
