Dukkanin kungiyoyin anyi masu allura ne da wani sinadarin rediyo wanda yake dauke da sinadaran serotonin da tsarin dopamine. Da zarar aka gudanar, mai watsa labarai na rediyo ya bayyana canje-canjen aiki a cikin wadannan tsarin ta hanyar auna tasirin rediyo a cikin thalamus, tsakiya da pons (wanda aka sani da aikin serotonin) da kuma a cikin striatum (wanda aka sani da aikatawa ta hanyar dopamine).

"Nazarinmu yana ba da hujja kai tsaye game da shigar da tsarin kwayar cuta ta kwakwalwa a cikin rikicewar zamantakewar marasa lafiya wanda ba shi da magani ko magani, "In ji Dokta van der Wee, MD, Ph.D., a sashen ilimin hauka da kuma Leiden Institute for Brain and Cognition a Leiden University Medical Center, Leiden (kuma a baya a Rudolf Magnus Institute of Neuroscience, University University Cibiyar a Utrecht, Netherlands). "Yana nuna cewa damuwar jama'a tana da wani bangare na dogaro da kwakwalwa."
Serotonin da dopamine (neurotransmitters, ko abubuwa da ke da alhakin canja wurin sakonni daga wani neuron zuwa wani) aiki a kan masu karɓa a kwakwalwa. Idan neurotransmitters ba su da daidaito, saƙonni bazai iya samun kwakwalwar ta hanyar dace ba. Wannan zai iya canza hanyar da kwakwalwar ta haifar da al'amuran zamantakewa, wanda ke haifar da tashin hankali.
Sauran nazarin neuroimaging sun nuna rashin daidaito a cikin glucose da kuma amfani da iskar oxygen a cikin kwakwalwa, a cewar van der Wee, wanda kuma ya nuna rashin hankali a matsayin ƙarin batun. "Yawancin mutanen da ke cikin wannan binciken na farko an san cewa tuni suna fama da cutar, don haka ba mu san ko abubuwan rashin lafiyar sun kasance ba kafin farawar cutar," in ji shi.
Dangane da nazarin da aka yi a baya, wasu masu bincike sun ba da shawarar cewa rikicewar rikicewar zamantakewar al'umma sakamakon sakamako ne na haɗuwa tsakanin kwayar halitta ko samuwar yanayin halitta da yanayin.
