What happens when you touch a hot object?
The nerves from whatever body part you are using lets the brain know that you should pull away from that object otherwise burning yourself Chactation: Fire has a large amount of thermal energy, when it comes into contact with your relatively cold hand, it's thermal energy quickly flows into it. The nerves in that area absorb that energy, transform it into a weak electrical signal, so your neurons can understand the information. The information is processed by the neurons, and then they decide on a logical reaction -pulling away from the intense heat-. That's my guess to how it happens. This all happens in a fraction of a second.

Do neurons physically changes their position when a person is happy or sad?
How does the CNS know weather a stimulus is strong or weak?
Nerves do not fire at varying intensities; for example, neurons won't fire at a stronger intensity if you're hit with a baseball in comparison to a marble. The difference between the two stimuli is the number of firing neurons. After being hit with a baseball, the affected neurons will fire more frequently than if hit with a marble.

What causes a neuron to fire?

What is happening when you are thinking?
When you are thinking, neurons in your brain are firing; they are caused to fire by inputs from the firing of other connected neurons, and the outputs of their firing causes other connected neurons to fire. However, since neurons have MANY MANY connections to many other neurons, any particular neuron is not SIMPLY or absolutely caused to fire just because one connected neuron fires, nor does its firing absolutely cause every neuron it connects to to fire; rather, neurons remember (through physical changes at synapses) which inputs have in combination been strong enough to cause them to fire, making them more sensitive and therefore likely to fire from a variety of similar inputs. Thus thinking is a neuro-chemical memory process, in which memories lead to memories by associations from within and without, and evoke ideas & concepts through novel combinations.
