Basa reNeurotransmitter Serotonin muMafungiro
Serotonin ndeimwe ye neurotransmitters inowanzo kurukurwa pakukurukura nezvemanzwiro, kushushikana, uye hutano hwepfungwa. Muchidimbu, neurotransmitters inyanzvi dzemakemikari dzinobatsira masero etsinga (neurons) kutaurirana. Serotonin, inozivikanwawo se5-hydroxytryptamine (5-HT), ine mabasa akasiyana-siyana mumuviri, asi mupiro wayo mukudzora manzwiro wakaita kuti ive chinhu chikuru muzvidzidzo zvakawanda zvepfungwa ne neurobiology. Chinyorwa chino chinokurukura kuti serotonin chii, mashandiro ayo, uye nei kuenzana kwayo kuchikosha kune manzwiro.
Chii chinonzi serotonin?
Serotonin ikemikari yechisikigo inogadzirwa nemuviri kubva kuamino acid tryptophan—chinhu chinowanikwa muchikafu. Kunyangwe ichiwanzobatanidzwa neuropi, serotonin yakawanda inowanikwa mudumbu. Chikamu chidiki chete ndicho chiri mutsinga huru, asi chikamu chidiki ichi chinoita basa rakakosha mumabasa epfungwa akadai semanzwiro, kuzvidya mwoyo, uye kunzwa zvakanaka.
Serotonin inoshanda nekuburitswa nema neuron mu synaptic cleft (nzvimbo diki iri pakati pema neuron), uko inosungana nema serotonin receptors pane mamwe ma neuron. Kusungana uku kunotanga zviratidzo zvakawanda zvinopesvedzera mashandiro etsinga. Serotonin inogona kutorwazve ne releasing neuron (reuptake) kana kuputswa nema enzyme chaiwo. Iyi system yekusunungura, receptor binding, uye reuptake ndiyo hwaro hwekuti serotonin inogona kukanganisa sei mafungiro.
Serotonin uye kugadzirisa mafungiro
Mafungiro anokonzerwa nekudyidzana kwakaoma pakati pezvinhu zvemuviri, zviitiko zvehupenyu, mafungiro, nharaunda, uye hutano. Serotonin haishande yega; inodzora zvakanyanya kukanganisa kugadzikana kwemanzwiro. Zvidzidzo zvakawanda zvinobatanidza huwandu hwakaderera hweserotonin nenjodzi yakawedzera yekuora mwoyo, kuzvidya mwoyo, uye kugumbuka. Zvisinei, zvakakosha kunzwisisa kuti hukama uhwu hausi nyore se "low serotonin = kuora mwoyo." Kuora mwoyo chirwere chinokonzerwa nezvinhu zvakawanda; serotonin chimwe chezvinhu zvemuviri chinogona kukonzera.
Serotonin inobatsira mukubatsira uropi kugadzirisa manzwiro nenzira yakaringana. Kana serotonin system iri kushanda zvakanaka, munhu anowanzova nekugona kwakadzikama kudzora kushushikana kwezuva nezuva, kutsungirira kusagadzikana kwepfungwa, uye kuchengetedza kunzwa kwakadzikama. Kusiyana neizvi, kana system iyi ikakanganiswa, maitiro emanzwiro anogona kuwedzera zvakanyanya, sekusuruvara kwenguva refu, kuzvidya mwoyo zvakanyanya, kana kuoma kuwana mufaro.
Sei serotonin ichibatanidzwa nekuora mwoyo?
Kubatana kuripo pakati peserotonin nekuora mwoyo kwava kuzivikanwa zvakanyanya nekuda kwekushandiswa kwemishonga inorwisa kushushikana inonzi SSRIs (Selective Serotonin Reuptake Inhibitors). SSRIs dzinoshanda nekudzivisa serotonin reuptake, zvichiita kuti serotonin igare musynapse kwenguva refu uye ive nemukana wakakura wekusunga kune mareceptors. Mukufunga, izvi zvinobatsira kusimbisa zviratidzo zveserotonin.
Zvisinei, migumisiro yeSSRIs inowanzova isingakurumidzi kuitika. Vanhu vazhinji vanongoona kuvandudzika mushure memavhiki akati wandei. Izvi zvinoratidza kuti kuwedzera kweserotonin pa synapse hakusi iko chete kunokonzera, asi kunokonzera kuchinja kwenguva refu muuropi, kusanganisira kuchinja mu receptor sensitivity, synaptic plasticity, uye kutonga kwe stress systems. Izvi zvinoreva kuti serotonin inogona kunzwisiswa se "chinokonzera" shanduko huru dzemuviri, kwete kungochinja kamwe chete kunosarudza manzwiro.
Serotonin, kuzvidya mwoyo, uye mhinduro yekushushikana
Kunze kwekuora mwoyo, serotonin yakabatanawo zvakanyanya nekuzvidya mwoyo. Serotonin inobatsira kudzora masero europi anobatanidzwa mukutya uye mhinduro dzekuchenjerera, kusanganisira amygdala. Mune mamwe mamiriro ezvinhu, kusawirirana kweserotonin kunogona kunyanyisa kunzwa kwehurongwa hwekutyisidzira hweuropi, zvichiita kuti zvive nyore kuti munhu anzwe kutyisidzirwa, kuzvidya mwoyo, kana kutya kunyangwe zvichikonzerwa nezvinhu zvidiki.
Serotonin yakabatanawo nehurongwa hwemahormone ekushungurudzika, kusanganisira HPA axis (hypothalamic-pituitary-adrenal axis), iyo inodzora kuburitswa kwecortisol. Kana kushushikana kukaramba kuripo, kudzora hurongwa hweserotonin kunogona kukanganiswa, zvichigadzira kutenderera kwakashata kunoomesa mafungiro: kushushikana kunokanganisa serotonin, uye kukanganiswa kweserotonin kunoita kuti munhu ave nyore kubatwa nekushushikana.
Hukama huripo pakati peserotonin nekurara, kuda kudya, uye simba
Manzwiro evanhu anobatanidzwa zvakanyanya nehunhu hwekurara, kudya, uye simba. Serotonin inobatanidzwa mune zvese zvitatu. Muuropi, serotonin inoita basa rekudzora kutenderera kwekurara nekumuka uye inotungamira kugadzirwa kwemelatonin, hormone inodzora kurara. Kushaikwa kweserotonin kunogona kusanganiswa nekushaya hope kana maitiro asina kurongeka ekurara, izvo zvinozoita kuti manzwiro awedzere kuipa.
Serotonin inokanganisawo chido chekudya uye kuguta. Nokudaro, kuchinja-chinja kwemafungiro kunowanzoenderana nekuchinja kwemaitiro ekudya—semuenzaniso, kudya zvakanyanya kana wakamanikidzwa kana kurasikirwa nechido chako kana wakasuruvara. Uyezve, nekuti serotonin inokanganisa maonero ehutano hwakanaka uye hutano, kusawirirana kweserotonin kunogona kukanganisa kukurudzira kwezuva nezuva nesimba.
Zvinhu zvinokanganisa mazinga e serotonin uye mashandiro ayo
Pane zvinhu zvakawanda zvinogona kukanganisa serotonin system, zvose zvakananga uye zvisina kunanga:
1. Kunwa tryptophan
Tryptophan ndiyo chinhu chakakosha pakugadzirwa kweserotonin. Zvikafu zvakaita semazai, hove, nzungu, chizi, tofu, nezviyo zvine tryptophan. Zvisinei, kugadzirwa kweserotonin hakungobvi pa tryptophan chete asiwo pakuenzanisa kwezvimwe zvinovaka muviri uye mamiriro emuviri.
2. Kuvhenekerwa nezuva
Ongororo dzinoverengeka dzakaratidza kuti kuratidzwa nechiedza kunogona kukanganisa mashandiro e serotonin. Izvi zvinowanzobatanidzwa nezviratidzo zve seasonal affective disorder (SAD) mune vamwe vanhu vanonzwa kuchinja-chinja kwemafungiro kana vasina chiedza chezuva.
3. Kurovedza muviri
Kurovedza muviri nguva dzose kunogona kutsigira ma neurotransmitters ane hutano, kusanganisira serotonin, uye kuwedzera zvinhu zvinosimudzira kukura kwetsinga, izvo zvinotsigira kusununguka kweuropi. Kutaura zvazviri, kurovedza muviri kunobatsirawo kuderedza kushushikana uye kunatsiridza kurara—zvinhu zviviri zvine chekuita nemanzwiro.
4. Hutano hwematumbu (gut-brain axis)
Nekuti chikamu chikuru che serotonin chiri mudumbu, kubatana kwedumbu neuropi kwakakosha. Dut microbiota inogona kukanganisa kugadzirwa kwemakemikari ane chekuita netsinga. Kusarongeka kwe microbiota nezvimwe zvinetso zvekugaya dzimwe nguva zvine chekuita nekuchinja kwemafungiro, kunyangwe hukama hwechikonzero huchiri kuongororwa.
5. Mageneti uye serotonin receptors
Kumwe kusiyana kwemajini kunogona kukanganisa serotonin transporter kana mareceptor ayo. Izvi zvinogona kutsanangura kuti nei vamwe vanhu vachinyanya kuva nezvirwere zvepfungwa kana kuti vanopindura zvakasiyana kune mimwe mishonga.
Kuchengetedza chiyero cheserotonin chine hutano
Kuramba uine mafungiro akanaka hakugone kurerutswa kuita "kuwedzera serotonin." Zvisinei, pane tsika dzakasiyana dzinogona kubatsira kutsigira mashandiro ese ehurongwa hweserotonin:
- Wana nguva yakakwana yekurara, nekuti kurara kunokanganisa kugadzikana kwepfungwa uye kushanda kwema neurotransmitters.
– Kurovedza muviri nguva dzose, semuenzaniso kufamba nekukurumidza kwemaminitsi makumi matatu kakawanda pasvondo.
- Kudya kwakaringana, kunosanganisira mapuroteni emhando yepamusoro, fiber, uye mafuta ane hutano.
– Kudzivirirwa nezuva, kunyanya mangwanani.
- Dzora kushushikana, semuenzaniso kuburikidza nekufungisisa, kunyora pasi, kana kupa mazano epfungwa.
- Tsvaga rubatsiro rwenyanzvi kana zviratidzo zvekuora mwoyo kana kuzvidya mwoyo zvichikanganisa mashandiro emuviri wako ezuva nezuva.
Kana mumwe munhu ari kufunga nezvekuwedzera mishonga kana mishonga inokanganisa serotonin, zvakanaka kuzviita pasi pekutarisirwa kwenyanzvi yehutano. Serotonin yakawandisa inogonawo kuva nengozi, senge mune chirwere chisingawanzoitiki chinonzi serotonin syndrome, chinoitika nekuda kwekusawirirana kwemishonga.
Mhedziso
Serotonin ineurotransmitter inokosha inobatsira mukugadzirisa manzwiro, kuzvidya mwoyo, kurara, kuda kudya, uye kushushikana. Inoshanda sechikamu che network yakaoma yehupenyu, saka manzwiro haasarudzwi nekemikari imwe chete. Zvisinei, kunzwisisa basa re serotonin kunotibatsira kuona kuti hutano hwepfungwa hune hwaro hwakajeka hwehupenyu, asi hunopesvedzerwawo nemararamiro, nharaunda, uye zviitiko zvepfungwa. Nemaitiro akaenzana—kubva patsika dzakanaka kusvika pakutsigira kwehunyanzvi—tinogona kuchengetedza muviri wedu nehuropi hwedu zvichishanda zvakanaka, zvichitungamira kumanzwiro akadzikama uye hupenyu huri nani.
