The dorsolateral prefrontal cortex (DLPFC) is a region located in the frontal lobe of the brain, specifically in the upper and outer areas. It plays a crucial role in higher cognitive functions, including decision-making, problem-solving, and working memory. The DLPFC helps individuals plan actions and manage complex tasks by integrating information from various sources. Additionally, the DLPFC is involved in regulating emotions and social behavior. It helps in controlling impulses and maintaining focus, which are essential for effective functioning in daily life. Dysfunction in this area can be linked to various mental health disorders, such as depression and schizophrenia.
