Does everyone brain react to 1 question in same way.. i mean trigger of reactions and is there way to measure?
If question asked 1+1 the brain is triggered with some action will it be same to all others and can the action be recorded and differenciated with other question like 2+2.
Answer:
No it will be different. The brain works in a complex way by creating many different networked pathways of nerve cells. One nerve cell may be connected to about a million other nerves as their endings branch out like long hands. It 'learns' by strengthening some pathways and weakening others. Some other pathways may also be destroyed by overuse or disease.
For a question like 1 + 1, the numbers 1 will activate their own network of cells. The addition sign will activate another.
With 2 + 2, its possible that the addition sign might activate the same networks, but the numbers 2 will activate other networks.
Also, if you compare adults who have already memorized such trivial maths, and kids doing maths for the first time, the reaction is different. An adult may have learnt to memorize the answers. Thus seeing 1+1 will activate memory cells for numbers instead for adults. For kids, the cells are still learning and as such the cells associated with numbers and mathematical operations will be activated instead.
The nerve cells itself transfer information electrically by other 'firing' or 'not-firing', or by 'firing' more times in one second or less times in one second. The 'firing' activity is influenced by chemicals called neurotransmitters. There are many types of neurotransmitters and they are released by a nerve cell each time they fire. The neurotransmitters get absorbed by nearby cells and if there are enough of it, the cell will fire.

You can measure electrical activity (firing or not firing, fast or slow) via an EEG or electroencephalogram by measuring electrical activity with electrodes on the scalp.
You can measure neurotransmitter activity via fMRI or functional magnetic resonance imaging. The 'f' means you want to find activity of a specific neurotransmitter. So you apply a chemical tracer which allows you to only see neurotransmitter G for example. The MRI machine will scan for the tracer and you can see all the areas in the brain where the neurotransmitter G has been active in.
The PET or positron emission tomography can measure deep brain activity by tracing blood activity. If a brain cell is more active, it will require more oxygenated blood which has different characteristics than deoxygenated blood. By putting a harmless temporarily radioactive protein tracer in the blood, you can find which areas of the brain is using oxygenated blood. fMRI can also trace oxygenated blood too. The blood signals are called BOLD contrasts (blood oxygen level dependant).
