Interesting neurotransmitters

I can't write about love no more
I should be feeling sad 
Now I know it wasn't you 
Who drove me mad 

It was that chemical stuff in my head 

Oh lalalalalalalalala 
Phenylethylamine 
Can't get enough 
Oh oh lalalalalala l'amour 

Noradrenaline 

Je comprends ~~

It makes me awake to have such an interesting lecture about amine neurotransmitters at 4pm when I am supposed to be half dead and it starts with this lyrics!

Got to know some trivias that might interest the Science students...

Noradrenaline (NA) is the love chemical!
It is said that feeling of being in love or in a crush is like having a NA rush in your body. Increasing NA in our brain gives us arousal and elevates our mood whereas depletion of it may be involved in depression. Sad to say, we are not able to increase NA concentration by taking tablets containing its precursors tyrosine because, the enzyme involved in the synthesis is saturated. So..what to do, you cannot create the feeling of being in love by taking tablets!

Dopamine is the addiction chemical! 
DA is involed in the control of attention, emotion and reward pathway. Also, the regulation of DA system in our brain is related to addiction of human beings to cocaine, amphetamine, cigarette and alcohol. It is said that because these drugs abuse may increase DA activity, which is linked to the reward pathway giving us a sense of pleasure. Hmmm, poor people, fooled by our own brain.

5HT (Serotonin) is the happiness chemical!
Serotonin is what gives us the feeling of happiness! High level of serotonin makes us awake and according to my lecture notes, it also makes us eat less and lose weight! On the other hand, low level serotonin gives you sleepiness and sedation and stimulate the feeding centre, which you tend to eat more.

And finally
Acetylcholine is the memory chemical!

Hahaha...Our brain is an amazing thing stuffed with all those complex systems of neurotransmitters! Hope there will be more fun coming on. hehehe.
