👉 The will fluid, also known as the prefrontal cortex's default mode network, is a dynamic neural network that plays a crucial role in self-referential thinking, planning, and decision-making. It is characterized by its fluid and flexible nature, allowing for rapid shifts in activity depending on the context or task at hand. This adaptability enables the brain to seamlessly transition between different mental states, such as daydreaming, problem-solving, or social cognition. The will fluid's ability to integrate diverse information and generate novel solutions makes it essential for creative thinking and effective decision-making.
