The prefrontal cortex is a region of the brain located at the front of the frontal lobe, and it plays a critical role in various higher cognitive functions, such as decision-making, planning, emotional regulation, and social behavior. Research on the prefrontal cortex focuses on understanding how this region contributes to complex behaviors and how dysfunction in this area may lead to various cognitive and emotional disorders, such as depression, anxiety, and addiction. Scientists use a variety of methods, including neuroimaging and animal studies, to study the prefrontal cortex and its functions. Understanding the prefrontal cortex is important for advancing our knowledge of brain function and potentially developing new treatments for cognitive and emotional disorders.
