A simple explanation of love by Helen Fisher. A presentation for February 14th party at a school of english language.

1. Love is…

2. “Tell me why the stars do shine,
Tell me why the ivy twines,
Tell me what makes skies so blue,
And I'll tell you why I love you.
Nuclear fusion makes stars to shine,
Tropisms make the ivy twine,
Raleigh scattering make skies so blue,
Testicular hormones are why I love you. ”
― Isaac Asimov

3. We have three types of love
1. Romantic love
2. Sexual drive
3. Long term attachment
Or this is only stages of one LOVE ))

4. Today we are concentrating on romantic love
Anyway, today is St. Valentine’s Day

5. What is love?
Or…
Something magical…

6. Love as it is seen by neuroscientists

7. Some words to learn
Neuron – a cell of nervous system.
Neurons contact each other by
means of special molecules –
mediators.
Neuron №1 Neuron №2
Mediator
Mediators can be different
End each mediator has its special function:
Everything which we do or feel is
because of mediators: sleep,
move, feel, think, LOVE

8. Love is real: evidence 1
Animals do feel love (at least some of them).
For example elephants.
Elephants are in love with each
other for 5 days

9. And another examples:
Some species of rodents (грызуны) can feel love too.
At least for 30 seconds.

10. And definitely human beings can
love.

11. Evidence 2
Our brain and whole organism are changing
when we feel love

12. The first symptom of love is…
“special meaning”
Not only the sweetheart…
…but everything connected with him
(her) seems absolutely unique!
• That is because of dopamine

13. When we fall in love, we can:
walk all night long
…without any sleep
That because
of dopamine
too!

14. We feel euphoric!
That because of dopamine again!
Dopamine is a really amazing mediator!

15. We think about him (or her) every minute,
every second of every day…
• That is because of serotonin:

16. Another changes:
The heart pounding
The sweaty palm syndrome
That’s probably high norepinephrine in the brain

17. So the mediators of love are:
• Dopamine -
• Serotonine
• Norepinephrine
thinking about sweetheart
special meaning
everything else

18. Is Eternal Love possible?
Fortunately, from scientific point of view, it is =)
At least for someone.

19. Long-term romantic love?
Yes  And not at all 
But commonly, yes ;)
Romantic love as intensive as in
the beginning of relationship is
inachievable =(
But romantic
feelings… yes,
they are possible!

20. What do we have to do to keep
love?
Science says the only
thing we need is
dopamine

21. ?
Where can we get it?
Pharmacy?
Definitely, not!
Can I have a
piece of
dopamine?
Does this recommendation help you?

22. • Just take up something new together 
It’s much simpler!
It's a piece of cake ))))))))))

23. And your dopamine level will grow!
The happy end of our
dream ))))

24. So what is love?
As scientists we can tell that love is definitely something magical
Some magical feelings which have a particular physiological basis

25. Enjoy!
