Summary: The text discusses the role of prefrontal cortex (PFC) in decision-making and communication within neural networks. PFC is involved in various cognitive processes such as working memory, executive functions, and social cognition. It plays a crucial role in decision-making by integrating sensory information, long-term memories, and emotional cues to guide behavior. Moreover, the PFC is also responsible for coordinating communication within neural networks by inhibiting unwanted signals and enhancing relevant information flow. Dysfunction of the PFC is associated with various psychiatric disorders like schizophrenia, depression, and addiction, highlighting its importance in maintaining mental health. Overall, the PFC serves as a key player in decision-making and neural communication, influencing various cognitive processes and behaviors.
