Similarities between Ancient Egyptians and Octopuses

In ancient times, the brain was not always recognized as the center of thought. The Egyptians believed that the heart was responsible for intelligence and contained the soul, so bodies were mummified with the heart intact while the brain was removed and discarded. It wasn’t until the Greek scholar Alcmaeon of Croton argued for the brain in the 5th century BCE that this belief began to change. However, Aristotle continued to assert that the heart was the seat of intellect two centuries later.

Interestingly, octopuses have a large number of neurons distributed throughout their tentacles, allowing each arm to react independently to stimuli. This challenges the idea that thought must have a central location. In the realm of artificial intelligence, models like ChatGPT exhibit behavior that resembles conscious thought, despite the lack of physical sensory organs.

Modern neuroscience and medical imaging have confirmed that in humans, the brain controls perception, thought, and language. However, the exact location of thought within the brain is still up for debate. Different cultures and religions have varying beliefs about the origins of consciousness, complicating the Western notion that intelligence is solely housed in the head.

Moreover, physical sensations like hunger and pain can originate from different parts of the body, yet our brains seamlessly integrate this information with our thoughts. If our stomachs and brains were reversed, we might perceive our head as a mere hub for sensory and dietary inputs, with conscious thought emanating from our midsection.

This article addresses the intriguing question posed by Billy Wilson about whether thinking would originate from the stomach if the brain were located there.
