Just like our senses, our body has signals like breathing, heartbeat, metabolism and other internal movements that may be considered a source of sensory input for the brain. This, when mixed with our original sensory inputs like touch, sight and hearing, can create emotions.

• Simulation is the standard, default mode for all brain activity.
• Discovered in the 1990s, simulation is what psychologists and neuroscientists mistook as ‘reactions’ to what we see, hear, touch, smell or taste.
• We automatically use simulation

Every moment that we are alive, our brain utilizes concepts to simulate the surrounding environment, practically creating ‘our’ world.
