COV TSWV YIM: kev cia siab ntawm kev muab nqi zog thiab kev tshoov siab cia siab rau cais nyob rau hauv qhov khoom plig loj dua. Kev txuam ua ke ua kom muaj kev zoo siab tshaj plaws, thiab nyob hauv xovtooj mus rau hauv lub hlwb. Internet porn = muaj kev cia siab txog kev pib tshiab.

Abstract
Kev Ntseeg thiab kev txhawb zog yog cov kev qhia muaj zog uas tsimnyog vam khom rau dopaminergic midbrain teb.
Cov kev tshawb nrhiav tsis ntev los no hais tias txawm hais tias muaj nqi zog thiab kev txhawb zog yuav muaj kev sib raug zoo, ob qho kev ua dej num yuav raug saib xyuas los ntawm cov neeg tsis sib haum xeeb.
Peb siv cov teeb meem loj (magnetic resonance imaging) (fMRI) los tawm tswv yim neural teb rau nqi zog thiab kev txhawb zog hauv cov tib neeg hauv cheeb tsam neeg (SN / VTA) txoj hauv kev los mus tshawb xyuas qhov kev sib haum xeeb thiab kev koom ua ke ntawm kev muab siab-thiab kev ua ub ua dej num tshiab tej pawg.
Peb pom tau hais tias cov pawg hauv cov kab sib cais hauv cov seem caudal ntawm SN / VTA thiab ib sab ntawm SN txoj cai yog feem ntau hloov los ntawm kev cia siab ntawm nqi zog, while ntau dua ib sab ntawm tus SN / VTA tshwj xeeb yog hloov tshiab los ntawm novelty.
Tsis tas li ntawd, qhov kev sib tw SNF / VTA claudal embodied kev sib raug zoo ntawm novelty thiab cov nqi zog uas novelty selectively tau nce nqi zog-kev cia siab rau cov lus teb. Qhov kev sib koom tes no, tig mus, tau qhov sib txawv ntawm cov qauv kev sib raug zoo ntawm cov cheeb tsam SN / VTA.
Tshwj xeeb, tshiab raws li piv rau cov nqi zog-kev xav ntawm stimuli nce cov kev sib txuas ntawm lub cev SN / VTA nrog thaj tsam mesolimbic, nrog rau cov nucleus accumbens thiab hippocampus, zoo li nrog cov thawj cortex.
Qhov kev haumxeeb no yuav qhia tau hais tias cov sijhawm SNF / VTA sib txuas lus tseem ceeb txog novelty thiab nqi zog, lossis, qhov kev sib tw SN / VTA yuav hloov kho cov txheej xwm tshiab rau cov kev txhawb nqa tshiab.
