Consciousness has been defined as "individual awareness of your unique thoughts, memories, feelings, sensations and environment."
Your own unique consciousness lives in a series of brain cells, or neurons, which, when fired in certain patterns, cause you to recall memories and emotions - even smells and sounds.
A study conducted at UCLA by lead researcher Martin Monti used fMRI scans to study how the flow of information in the brains of 12 healthy volunteers changed as they lost consciousness under anesthesia with propofol. They concluded that "consciousness does not “live” in a particular place in our brain but rather arises from the mode in which billions of neurons communicate with one another."
So will it ever be possible to accurately map an individuals intricate and totally unique consciousness, and upload it into another mind?
According to AsapSCIENCE, the short answer is yes - it will be become possible one day.
Take a look at their video explaining the necessary processes and knowledge required to make it possible.
