Rather than producing consciousness, the brain may function more like a receiver or interface that filters a much larger reality into a manageable human experience. In this view, the brain organizes incoming information into the sensory categories we experience as touch, sight, smell, hearing, and taste. This idea suggests that human perception may not represent reality in its entirety, but instead a limited interface that allows us to navigate the environment efficiently.
At the same time, research in vision science shows that human sensory systems detect only a small portion of the physical signals present in the environment. For example, human vision responds only to electromagnetic radiation within the visible spectrum, approximately between 400 and 750 nanometers. According to Polishchuk and Tykhanova (2022), the human visual system is adapted to perceive only this narrow portion of electromagnetic radiation, meaning that most electromagnetic signals exist outside of human perception.
For example, some animals can perceive forms of light that humans cannot. Bees can detect ultraviolet patterns on flowers that guide them to nectar, while snakes can sense infrared radiation to detect body heat from prey. These examples show that different organisms experience different versions of the same environment depending on their sensory systems.
Because our sensory systems detect only a limited range of information, our experience of reality may be both constrained and constructed. The brain receives filtered sensory input and must interpret and organize these signals before they become conscious perception.
