Various that can think and feel – be

Various Sci-Fi movies have shown the possibility of there being an artificial brain in the future, one that is fully conscious and is fully advanced. For example, a particular scene in Ex Machina showcases an artificial brain in which can be put inside a robot, and then the robot is completely conscious. But exactly how far are we from replicating the human brain, and what stages must we take in order to achieve this goal?Firstly, we must know exactly what the brain does, how it functions and what parts are responsible for what action. In addition to this, we must come up with a universal definition of what a brain does, so that we can objectively label the prototype should it meet all the criteria. Without this, some people may claim to have made an artificial brain, and yet some scientists may come along and say that it is not an artificial brain since it does not meet their criteria.According to Collinsdictionary.com, your brain is the organ inside your head that controls your body’s activities and enables you to think and feel things such as heat and pain. Assuming that this definition is correct, it would allow us to form a basis that the artificial prototype must perform in order for it to be considered to be a brain. In this case, it is something that can think and feel – be self-aware and conscious.Human brains are composed of around 40% gray matter, and 60% white matter. Gray matter is a major part of your central nervous system and consists of billions of neurons that transmit signals. White matter is made of axons and dendrites in which transmits neurological signals between synapses (called synaptic transmission.)Imagine your brain to be like a circuit – it sends electrical impulses throughout the circuit until it reaches the end. Essentially when we are making an artificial brain, we must create billions of circuits that transmit signals to one another. Although we can make billions of circuits, it would take up a lot of space and time. If we effectively created these circuits, more work would still need to be made to make it conscious, self-aware, and self-improving. This is because there is no chemicals within the circuits to stimulate emotions such as adrenaline and serotonin.Of course, we can create a model of the brain and assume how it works, yet we still cannot know for sure of it’s functions and exactly what is needed for an artificial brain for to work effectively. However, maybe the more important question is not how we can replicate the human brain, but instead how can we ‘transfer people’ into artificial stores so that human’s lives can be prolonged?It is assumed that our memories are stored in our hippocampus, amygdala, neo cortex, basal ganglia, cerebellum and the prefrontal cortex. Since memories are stored within certain parts of the brain, and memories are associated with emotions, what if one day we can create a store for long term memories of a person and then upload it to a robot so that they are still there, just in a different body?The steps that we need to take in order to achieve these goals is research. As boring as it sounds, we do not yet fully understand the brain, and exactly what functions different areas do. When we get a better understanding, we may be able to attempt this and potentially create better humans by manipulating data through removing bad traits of humans and then changing them to good ones such as better memory, or even make our species smarter. If we could do this, then we could rapidly increase the evolution of our species and have the opportunity to constantly improve.
