What is consciousness? This is perhaps the greatest mystery remaining in the human brain. No wonder it's known as the “hard problem.” We also cannot agree on whether consciousness is one thing or whether it is various states. But a new way to explore that question sheds interesting light on this most elusive of concepts.
We use words like “blacking out” to describe fainting or falling asleep, but researchers believe that consciousness is much more than simply flipping a metaphorical switch from “on” to “off.” I have long understood that it is complicated. However, there is still much debate as to whether it is a single phenomenon with many continuous shades, as imagined as a dimmer switch, or a collection of discrete states, like separate television channels. there is.
Thinking about consciousness from a physicist's perspective may help answer this question. That's because the brain is constantly transitioning between states defined by patterns of electrical signals, and physicists have metrics to study such busy, ever-changing systems. In 2014, robin carhart harris University of California, San Francisco and colleagues hypothesized that entropy may be particularly useful.
Entropy describes how chaotic a system is. One measure of entropy is how many different microscopic configurations (such as the arrangement of water molecules within a glass) exist within a particular macroscopic property (such as the volume of a glass). Researchers proposed that brain states have greater entropy when measured…
