Even senses that seem fundamental, such as vision, are intimately entwined with other senses that seem separate.<\/p>\n
For example, it turns out that what you see, and how you see it, is yoked to your brain\u2019s tracking of your heartbeat, which is part of interoception.<\/p>\n
In the moments when your heart contracts and pushes blood out to your arteries, your brain takes in less visual information from the world.<\/p>\n
Your brain also constructs senses that you don\u2019t have receptors for. Examples are flavour, which the brain constructs from gustatory (taste) and olfactory (smell) data, and wetness, which is created from touch and temperature.<\/p>\n

Light waves, for example, don\u2019t simply enter your eyes, travel to your brain as electrical signals, and then you see.<\/p>\n
Your brain actually predicts what you might see before you see it, based on past experience, the state of your body and your current situation. It combines its predictions with the incoming sense data from your retinas to construct your visual experience of the world around you.<\/p>\n
Similarly, when you place your fingers on your wrist to feel your pulse, you\u2019re actually feeling a construction based on your brain\u2019s predictions and the actual sense data. You don\u2019t experience sensations with your sense organs. You experience them with your brain.<\/p>\n
