What does PRES mean in UNCLASSIFIED

The Perceive-React-Execute Switches (PRES) model proposes that a particular type of neuron, called a PRES neuron, plays a critical role in decision-making and action selection. These neurons are found in the brain's basal ganglia and receive input from various brain regions involved in perception, cognition, and motor control. The PRES model suggests that PRES neurons help the brain to perceive sensory information, react to it, and execute appropriate actions.

PRES neurons are characterized by their ability to switch between two distinct states: "Perceive" and "React/Execute." In the "Perceive" state, PRES neurons receive input from sensory and cognitive areas of the brain and encode information about the current situation. When the brain needs to make a decision or take action, PRES neurons switch to the "React/Execute" state. In this state, they send signals to motor areas of the brain, triggering the execution of appropriate actions.

PRES neurons play a crucial role in decision-making by integrating information from different sources and selecting the most appropriate action. They receive input about the current situation, potential rewards and punishments, and the individual's internal state. By processing this information, PRES neurons help the brain to evaluate options, make decisions, and initiate actions.

The PRES model provides a framework for understanding how the brain makes decisions and selects actions. It highlights the importance of specific neurons in the basal ganglia and their role in integrating sensory, cognitive, and motor information. The model has implications for research on decision-making, movement disorders, and neuropsychiatric conditions that affect these processes.
