Mahusiano kati ya Mapenzi na Ubongo

By FRANK KIMARO

Unaweza kushangaa kwa nini mtu kwenye mapenzi anaweza kuitoa sadaka ndoa yake, familia, mali au chochote chenye thamani kwenye maisha yake kwa sababu ya kitu kinaitwa Penzi.

Madaktari mbalimbali wamejaribu kufanya chunguzi kwa nini mapenzi yanaweza kutufanya kuwa watumwa, wenye furaha kupitiliza au wenye majonzi.

Technolojia ya "KUSCAN UBONGO" inawaruhusu wataalamu kutambua nini kinachoendelea kwenye ubongo wakati tumeanguka kwenye mapenzi.

 

Wanaona mabadiliko kwenye ubongo na kugundua sehemu zilizo kwenye ubongo ambazo zinaathirika kutokana na penzi vilevile sehemu ambazo zinashindwa kufanya kazi hususani unapokuwa na Unayempenda.

Zaidi ya hivyo teknolojia hiyo inaonesha jinsi mapenzi yanavyoweza kukufanya ukawa mgumu kufanya maamuzi na maisha yako kuendeshwa na hisia huku uwezo wa kufikiria ukishuka.

Wanasayansi wanategemea siku moja itaonesha jinsi gani tunaweza kuvuka mipaka ya malengo yetu tuliyojiwekea kwa sababu tu ya kupenda.

SEHEMU ZA UBONGO ZINAZOATHIRIKA NA MAPENZI

The frontal cortex- vital to judgment, shuts down when we fall in love. MRI scans show this de-activation occurs only when someone is shown a photo of the person they adore, causing them to suspend all criticism or doubt.

Semir Zeki, professor of neuro-aesthetics at University College London, says: ‘When you look at someone you are passionate about, some areas of the brain become active,’ he says. ‘But a large part is de-activated, the part that plays a role in judgment.’

Prof Zeki believes the brain may behave in this way for ‘higher biological purposes’ – it makes reproduction more likely. If judgment is suspended, the most unlikely pair can get together and reproduce. Someone in love will still be capable of making other major decisions in their lives, from striking a business deal to choosing a new mortgage.
And this sanity makes it harder for friends to convince them  ‘they have taken leave of their senses’ when it comes to an ill-advised affair.
Brain scans have also shown the area of the brain that controls fear, and another region involved in negative emotions, close  down, explaining why people feel  so happy with the world – and unafraid of what might go wrong – when they fall head over heels.

LOVE IS THE DRUG
Studies have shown brain chemical dopamine is at higher levels in those in love. Dopamine is key to our experiences of pleasure and pain, linked to desire, addiction, euphoria, and a surge may cause such acute feelings of reward that it makes love hard to give up.
Tests show that taking opioid drugs such as cocaine have a similar effect on dopamine as love.
A side effect of rising dopamine levels is a reduction in another chemical, serotonin, a key hormone in our moods and appetite.

Scream for love: Levels of adrenaline released when frightened means that two people going
 through a scary experience together can fall madly in love

Serotonin levels may fall in a similar way to those seen in people with obsessive-compulsive disorder, explaining why love can make us feel anxious and jittery.
The love chemical we are most familiar with is adrenaline. This hormone is why our heart races, palms sweat and mouth goes dry when we see the person we like.
The same hormone is also released when we are frightened. This means that two people only vaguely attracted to one another can fall madly in love if they go through an exciting or scary experience together. It may also explain the lure of forbidden love.

OUT OF CONTROL LOVE
Psychologists are still trying to understand why some become dangerously obsessed and risk everything for love. Dr David Nias is a psychologist and author on love, and a specialist in stalkers. Although an extreme end of the ‘love spectrum’, stalkers do shed light on why people do inconceivable things when in love.
‘The emotion of love snowballs for stalkers. It becomes a mental disorder and leads them to be delusional. Sadly we don’t know much more about its causes.’
But if someone gets treatment in which they learn to think  differently and often more positively, they can recover from their obsession and look back in amazement at how they behaved.
Dr Nias says there is a distinct personality type involved in this one-sided love: the over-emotional and highly imaginative
