Ljubezen - skoraj isti učinek kot heroin! (part 2)

Nadaljevanje iz prejšnjega dela, "O ljubezni in drugih boleznih", dostopno tukaj.

...
No, pravite, kaj pa navezanost! (Če se izognemo neprijetnemu oksitocinu s svojimi ... "intoksikantnimi" učinki.) Kaj pa to, ko mi srce poskoči, ko vidim svojega lubija ali pa čebelico in občutek, da bo skoraj konec sveta, če se nekaj časa ne vidiva? Hm, v besedi: withdrawal.

This is down to dopamine, the brain’s pleasure chemical. When nerve cells squirt small amounts of this into a brain region called the nucleus accumbens it produces sensations of euphoria and satisfaction.

Nadalje pa sem marca ali aprila lani poslušal iPod brata kolegice, ki mi je dal misliti - v bistvu je bil Podcast the naked scientists, ki se je ukvarjal ravno s to tematiko. Podcast, ki je ustvaril pričujoči članek.

Internetni članek (glej tudi spodaj) navaja, da je dopamin v telesu v uporabi, da se ojačajo nagrajujoča vedenja: ko se nekaj naučimo ali naredimo nekaj dobrega za nekoga ali ... vzamemo heroin ali kokain, ki delujeta na iste živčne končiče kot dopamin - vsi nam dajo občutek zadovoljstva.
  Torej, ko delujeta oksitocin in vazopresin, ko so njuni kemični signali prisotni in aktivni v telesu (možganih!),

they trigger the release of an addictive surge of dopamine in order to consolidate their effects. So you are, quite literally, getting hooked on your partner. 

Svoj sestav avtor zaključuje z nasvetom in mislij, da je sicer fino, da znamo razčleniti ljubeznesko dogajanje v telesu na peščico kemikalij, da pomaga znanstvenikom in zdravnikom, da lahko ljudem, ki ne morejo navezovati stikov, na primer avtistom, pomagajo pri tvorbi odnosov .. Svari pa tudi, da se dá taka znanja krepko izkoristiti in da sedaj, zaenkrat še nedolžna fraza v prihodnosti: "A lahko samo tole malce poduhaš?" morda ne bo več tako nedolžna.

 Ta in prejšnji del sta povzeta po članku na internetni podstrani The Naked Scientists, 'What is love?' Chrisa Smitha.

O ljubezni in drugih boleznih, part 1

Za to, da nekatere kemikalije močno vplivajo na to, kako doživljamo soljudi - predvsem partnerje - sem slišal že v prvem letniku biologije, ko sva s tedanjo punco za pozabljivost in "hojo v oblakih" krivila oksitocin.

Oxytocin is released in the brain during orgasms, during childbirth and by breast feeding, which has led scientists to suspect that it may be linked to mother-baby bonding and that perhaps this, “love” and partner attachments are all a manifestation of the same process.

Nadalje je mojo pozornost pri predavanjih biokemije pritegnil seminar kolegice z naslovom: "Ljubezen po biokemijsko", kjer sem slišal tudi za vazopresin in podobne 'reagente" ...
  But trust also usually demands monogamy, the mediator of which is vasopressin. Studies on voles have shown that a polygamous vole species known as the meadow vole can be transformed into behaving like its monogamous prairie vole cousin either by adding extra vasopressin to its brain or by increasing the brain’s sensitivity to the substance.  
  Pa da ne ostanemo zgolj pri nekih glodalcih v savani ali preriji, evo vam nadaljevanje: 

The same seems to apply to humans: a study carried out last year in Sweden found that individuals with one variant of a gene used in the brain to detect vasopressin levels were twice as likely to report a recent marital crisis, and only half as likely to be married in the first place, compared with individuals not carrying that form of the gene.  

 Administering vasopressin to volunteers also produces changes in behaviour. Men adopt a more aggressive posture including looking more menacing and also becoming much more protective of their partners. And when shown photographs of other peoples’ faces they tend to rate them as looking less friendly than they did before vasopressin was given.

No, pravite, kaj pa navezanost! (Če se izognemo neprijetnemu oksitocinu s svojimi ... "intoksikantnimi" učinki.) Kaj pa to, ko mi srce poskoči, ko vidim svojega lubija ali pa čebelico in občutek, da bo skoraj konec sveta, če se nekaj časa ne vidiva? Hm, v besedi: ...

O dopaminu, njegovih učinkih, kokainu in heroinu ter zaključku ... v naslednjem delu.

Post-able things, objavabilne stvari

Torej - bolj zame - razlozim ob priliki, ampak: objavljal bom v ta post stvari, ki bi jih rad prilimal nekam drugam (blogger ustvari link do slike, ki jo up-loadas ... ergo...)

Torej - ni za branje, temveč za jemanje! Jemljite resno! ;)

'Ach, CRIVENS!'

Iz ene zlo fajn knjige od Terryja Practhetta, ki sem jo prebral ravno danes:
A Hat Full of Sky.
  p.46
'Aye, weel, this is different-' Rob Anybody began, but stopped.
  He hadn't been a husband for very long, but upon marriage men get a whole lot of extra senses bolted into their brain, and one is there to tell a man that he's suddenly neck deep in real trouble.
  Jeannie was tapping her foot. Her arms were still folded. She had the special smile women learn about when they marry, too, which seems to say 'Yes, you're in big trouble but I'm going to let you dig yourself in even more deeply.'
43
  'Still, that's my name, right?' he said, grinning.
  Jeannie nodded.
  'Just there, all by itself and no' on a Wanted poster or anything. My name, drawn by me.'
  'Yes, Rob,' said the kelda.
  'My name under my thumb. No scunner can do anythin' aboot it? I've got my name, nice and safe?'
  Jeannie looked at the toad, who shrugged. It was generally held by those who knew them that most of the brains in the Nac Mac Feegle clans ended up in the women.
  'A man's a man o' some standin' when he's got his own name where no one can touch it,' said Rob Anybody. 'That's serious magic, that is-'
  'The R is the wrong way roond and you left the A and Y out of "Anybody",' said Jeannie,
because it is a wife's job to stop her husband actually exploding with pride.
  'Ach, wumman, I didna' ken which way the fat man wuz walkin',' said Rob, airily waving a hand.
'Ye canna trust the fat man. That's the kind of thing us nat'ral writin' folk knows about. One day he might walk this way, next day he might walk that way.'
  He beamed at his name: ßoB NybO D

p. 349:
Why do you go away? So that you can come back. So that you can see the place you came from with new eyes and extra colours. And the people there see you differently, too. Coming back to where you started is not the same as never leaving.
338
Granny nodded. 'There's always a story,' she said. 'It's all stories, really. The sun coming up every day is a story. Everything's got a story in it. Change the story, change the world.'
331
She stood there watching the mountains until, after about an hour, a dot in the sky got bigger and bigger.
  As a Kelda, she would welcome home a warrior. As a wife, she would kiss her husband and scold him for being so long away. As a woman, she thought she would melt with relief, thankfulness and joy.

DOPPS je včeraj vložil tožbo proti okoljevarstvenem soglasju za VE Volovja reber

Ljubljana, 9. 12. 2010

Včeraj je odvetnik Tomaž Petrovič, ki v prizadevanjih za ohranitev Volovje rebri zastopa DOPPS, na Upravnem sodišču vložil tožbo zoper Agencijo RS za okolje (ARSO), in sicer za razveljavitev Okoljevarstvenega soglasja za Vetrno elektrarno Volovja reber.

V skladu z zakonom o Varstvu okolja ima Upravno sodišče zdaj 3 mesece časa, da o tožbi razsodi. Gre za zadnjo pravno inštanco v Sloveniji.

DOPPS opozarja, da gre v »primeru Volovja reber« za precej več, kot le za ohranitev same Volovje rebri. Gre za precedenčen primer varstva območij Natura 2000, saj je to prvi primer velikega škodljivega posega v Natura območja v Sloveniji. Velik problem je, da sta ARSO in Ministrstvo za okolje v tem primeru uvedla prakso dela, ki močno odstopa od zahtev evropske naravovarstvene zakonodaje in posledično onemogoča varstvo Natura območij v Sloveniji.

Uffa!

Chuck Norris' tears can cure cancer... To bad, he never cries.
For those of you who want to find Chuck Norris, go here.

Objemi svojega bliznjega ... MY ASS!

ETO, TO MI NI JASNO: kako lahko LJUDJE POSILJAJO take maile naokoli, ko pa hocem ravnati po teh dobrohotnih nasvetih (in lastni vesti in srcu), naletim na ZGRAZANJE in GROZO?
... ce plesem, ko mi pase, je cudno, ce pojem, ko sem vesel, je noro, če bi rad objel nekoga, ker je lep dan, ker sem vesel, ker se mi zdi, da je človek potrt in rabi objem, ..., je ljudem nerodno.

In potem, na vsake toliko, dobim mail, kot ta, katerega delček pripenjam spodaj. KJE JE TU RESNICA, kje PRAVICA? "Have we turned INTO GERBILS, ladies and gentleman?" A nihče več nima jajc, da bi živel, kot o tem sanja in delal dobre stvari dobrim ljudem?
Ampak ne, LEPO in SPODOBNO pa je poslati PIVO ali CVETJE ali povabilo za neko noro dobro novo igro tipa MafiaVampireVille PO F* FACEBOOK-u? Pa a me zezate?

//Spomnite se, da daste topel objem tistemu zraven vas, ker je to edino
imetje,ki ga lahko daste s svojim srcem, a ne stane niti pare.//
//Pomnite: preživite nekaj časa z vam dragimi, ker oni ne bodo tu tudi večno.
Pomnite: recite kakšno prijazno besedo tistemu, ki vas gleda s
strahospoštovanjem, ker bo ta majhna oseba skoraj odrasla in odšla.//

Science and World Time

Stand back ...
... and many other, really cool comics and snippets (what's a snippet - surely not a small-sized, funny piece of information?) are available to everyone with an ounce of sense for surfing + on xkcd for those, less prone to i-waves.
  On another note (or more likely, the same), I found the picture I'm posting bellow, undoubtedly from xkcd.com as well - this and similar problems about the world always nagged me. It's kind of ironic, isn't it, when you think about it.
  The other day I was trying to explain something to this Dutch girl - how we are from Slovenia and always try to portray ourselves as being in Central Europe, but we're happy if the put us in the Southern Europe as well (if Italy's in, so can we) and how we don't like it if they try to mentally shuffle us into Eastern Europe - enough confusion there, with "Oh, yeah, you guys split up with Cheque sometime ago now, eh?" No, darn it! That was the Slovaks, were Slovenians ... What an unfortunate choice of names ...
  But then again - we can spell LOVE to whomever we write in Slovenia. Just how cool is that!?
