Vuto lakutchova juga (PG) limawoneka ngati chizolowezi chofananira ndi kugwiritsa ntchito mankhwala osokoneza bongo, m'malo mothana ndi vuto lotha kuwongolera, komabe makina osokoneza bongo sanadziwikebe. Kufufuza kwa Neuroimaging kwathandizira lingaliro la "kuchepa kwa mphotho" kwa PG pofotokoza yankho lolakwika panjuga, makamaka mu striatum. Apa tikufotokozera za ma electrophysiological of a hypersensitive reaction to juga mayankho pamavuto omwe amatchova njuga. Kafukufuku wam'mbuyomu mwa omwe adatenga nawo gawo pazaumoyo akuwonetsa kuti mayankho omwe amapezeka pantchito yotchova juga amayambitsa mayankho ophatikizika amtundu wa Feedback-Feedback-Related Mediofrontal Negativity (FRN), P300 yokhudzana ndi mayankho, komanso kuchuluka kwa mphamvu ya theta-band (4-8 Hz). Tinayesa lingaliro loti kusanja mayankho osazolowereka kumadziwika muzochita zamaubongo omwe ali ndi vuto lotchova njuga pomwe amatchova juga. EEG idalembedwa kuchokera kwa omwe sanali otchova juga komanso omwe amadziwika kuti ndi otchova juga pomwe amachita nawo kompyuta ya Iowa Gask Task. Malingaliro okhudzana ndi valence (win vs. loss) adadzetsa FRN m'magulu onse awiriwa, koma mwa otchova juga izi zidatsogoleredwa ndi kusiyana kwapakatikati kwa latency hypersensitive fronto-central pakuyankha. FRN yoyambayi idalumikizidwa ndi kuopsa kwa kutchova juga ndipo idasinthidwa kukhala kotsogola kwamankhwala ogwiritsa ntchito kulingalira kochokera kumagwero (CLARA). Otchova juga nawonso amasiyana mayankho pachiwopsezo, kuwonetsa gawo lopanda P300 ndi mphamvu zochepa za EEG mgulu la theta. Apa tikuti kutanthauzira koperewera koperewera kwamaphunziro kumafunikira pokhudzana ndi PG. Pazinthu zina za ntchito yaubongo, otchova njuga amatha kuwonetsa kuchuluka kwa Hypersensitivity kuti alandire mayankho ofanana ndi kukopa kwa mankhwala kuposa kuchepa kwa mphotho. Zotsatira zathu zimasonyezanso kuti ubongo wamtundu wanthawi zonse umagwiritsa ntchito ziwalo zina poyanjana ndi mayankho ochokera pantchito zopanga zoopsa.
