what are the reasons that we refer to ourselves as humans, when really.. we are neurons. that's the "i" i think. the neurons... i am not my hand -.- that is a biological machine. a tool.. a slave to be used by the sentient cells.. neurons 
Yes, we are our neurons. If you damage your Broca's area, you will end up like this:
Damage to your medial temporal lobe will leave you like this:
Frontal lobe damage can cause you to have problems like this man:
Bilateral hippocampi damage will cause you to live "perpetually in the moment," with no awareness of what had just happened moments ago.
Temporal lobe epilepsy can cause people to have profound spiritual and philosophical episodes, and can even make them feel like they are God during an episode.
I really could go on and on. Glial cells and the chemical composition of our brains are also very important. But yes, when it comes down to it, "we" are the 3 pound gelatinous masses inside of our skulls.
