Integrated information theory
Consciousness is identical to integrated information (Φ)
Integrated information theory (IIT) posits a unique perspective on consciousness, equating it with the quantity of integrated information (Φ) within a system.
IIT suggests that consciousness arises from a system's causal structure, meaning that the subjective experience of a physical system can be mathematically described by its causal powers.
The theory has practical applications, such as developing clinical techniques to assess consciousness in unresponsive patients, demonstrating its relevance beyond theoretical discussions.
Example
A patient's brain activity is analyzed to determine their level of consciousness using IIT's framework, providing a concrete method for assessing consciousness in clinical settings.
Understanding IIT's proposition helps bridge the gap between subjective experiences and objective measurements in consciousness studies.
