Whao its really interesting question sweetie..
Answer is Yes, We can find out in MRI if somebody is in love and even we differentiate thru MRI is it love or lust???

Actually,Dr. Brown and his colleagues have done one study over it in Albert Einstien College of Medicine in NewYOrk. The scientists found that the caudate area of the brain -- which is involved in cravings -- became very active. Another area that lit up: the ventral tegmental, which produces dopamine, a powerful neurotransmitter that affects pleasure and motivation.

Dr. Brown said scientists believe that when you fall in love, the ventral tegmental floods the caudate with dopamine. The caudate then sends signals for more dopamine.      
"The more dopamine you get, the more of a high you feel" :happy:

If a packet hits a pocket on a socket on a port,
And the bus is interrupted as a very last resort,
And the address of the memory makes your floppy disk abort, Then
the socket packet pocket has an error to report!
