U may have been thought the wrong thing, but from what I have heard, your nerves keep sending signals to your brains about the situation, problem is, if there are no nerves left because they got cut of, where the >!fuck!< do those signals come from?
In: Biology
You bring a candle to your hand. You feel the heat and get burned.
When that happens, the neurons in your brain corresponding to various stimuli link together:
The sight of the candle coming near to your hand.
The increase in heat.
The actual burning sensation.
Each of those triggered different neurons in your brain to fire and when they fire together connections are established. The cool thing about these connections is, once created, one grouping can be used to activate another. So maybe next time you only see the candle coming toward your hand and the group of neurons associated with seeing that activates. That activation travels down those preestablished connections and activates the group of neurons associated with feeling the increase in heat (whether or not there is an increase of heat) and a burning sensation (whether or not there is actually a burning sensation).
So you can “feel” a burning sensation in an arm that isn’t there because the burning sensation was never created by your arm to begin with, it was created by your brain and that part of your brain can be activated through existing connections to other neurons firing.
