Ak\u010dn\u00fd potenci\u00e1l je prostriedok bunkovej signaliz\u00e1cie, ktor\u00fd sa uskuto\u010d\u0148uje, ke\u010f kladne nabit\u00e9 i\u00f3ny vstupuj\u00fa do buniek a sp\u00f4sobuj\u00fa r\u00fdchlu zmenu elektrick\u00e9ho prostredia v bunkovej membr\u00e1ne, aby dosiahli hrani\u010dn\u00fa hodnotu. To n\u00e1sledne vy\u0161le elektrick\u00e9 sign\u00e1ly do inej bunky, aby akt\u00edvne reagovala. <\/p>\n\n\n\n

Sign\u00e1l je tak\u00fd r\u00fdchly, \u017ee koris\u0165 zachyt\u00ed v priebehu nieko\u013ek\u00fdch sek\u00fand. <\/p>\n\n\n\n

Koris\u0165 sa tr\u00e1vi pomocou enz\u00fdmov uvo\u013e\u0148ovan\u00fdch \u017e\u013eazami na v\u00fdstelke listu. Rastlina absorbuje potrebn\u00e9 \u017eiviny, aby mohla pokra\u010dova\u0165 v \u010dinnosti.<\/p>\n\n\n\n

D\u00f4vodom je pozorovanie a experimentovanie:<\/strong><\/p>\n\n\n\n

Podobne ako \u013eudsk\u00fd mozog je zodpovedn\u00fd za zmeny nap\u00e4tia v ur\u010dit\u00fdch oblastiach, ktor\u00e9 sa objavuj\u00fa ako elektrick\u00e1 aktivita vo forme ak\u010dn\u00fdch potenci\u00e1lov, ktor\u00e9 prech\u00e1dzaj\u00fa nervov\u00fdmi bunkami. Tieto aktivity mo\u017eno odhadn\u00fa\u0165 pomocou techn\u00edk, ako je magnetoencefalografia, elektroencefalografia a magnetick\u00e1 rezonancia, na anal\u00fdzu potenci\u00e1lnych por\u00fach a ich diagnostiku.<\/p>\n\n\n\n

Skupina interdisciplin\u00e1rnych v\u00fdskumn\u00edkov preuk\u00e1zala jedine\u010dn\u00fa magnetick\u00fa aktivitu mucholapky v spojen\u00ed s jej elektrickou signaliz\u00e1ciou podobn\u00fdm sp\u00f4sobom ako u \u013eud\u00ed.<\/p>\n\n\n\n

Mechanizmus Venu\u0161inej pasce je tie\u017e zalo\u017een\u00fd na ak\u010dnom potenci\u00e1li, ktor\u00fd vedie k elektrick\u00fdm sign\u00e1lom v syst\u00e9me.<\/p>\n\n\n\n

Ak\u010dn\u00fd potenci\u00e1l Venu\u0161inej mu\u0161ky m\u00f4\u017ee by\u0165 vyvolan\u00fd teplom, chladom, obsahom vody a in\u00fdmi mechanick\u00fdmi alebo environment\u00e1lnymi faktormi. Vedci pou\u017eili teplo na vyvolanie ak\u010dn\u00e9ho potenci\u00e1lu na meranie magnetick\u00e9ho po\u013ea, preto\u017ee si v\u0161imli, \u017ee teplota ovplyv\u0148uje amplit\u00fadu ak\u010dn\u00e9ho potenci\u00e1lu.<\/p>\n\n\n\n

Na meranie biomagnetizmu spojen\u00e9ho s elektrickou aktivitou pou\u017eili at\u00f3mov\u00e9 magnetometre. Pou\u017eit\u00e9 senzory boli sklenen\u00e9 \u010dl\u00e1nky, ktor\u00e9 boli naplnen\u00e9 parami alkalick\u00fdch at\u00f3mov, ktor\u00e9 reagovali na zmeny biomagnetickej aktivity.<\/p>\n\n\n\n

Magnetometre vy\u017eaduj\u00fa na meranie magneticky tienen\u00e9 prostredie. Ide o prevent\u00edvny krok, aby bolo mo\u017en\u00e9 mera\u0165 len magnetick\u00fa aktivitu viacbunkovej rastliny. Tento n\u00e1stroj je ve\u013emi \u00fa\u010dinn\u00fd a uprednost\u0148uje sa pred magnetometrami so supravodiv\u00fdm kvantov\u00fdm rozhran\u00edm (SQID), preto\u017ee sa daj\u00fa miniaturizova\u0165 pre optim\u00e1lne priestorov\u00e9 rozl\u00ed\u0161enie pri meran\u00ed \u00fadajov.<\/p>\n\n\n\n

Magnetick\u00fd sign\u00e1l Venu\u0161inej pasce, ktor\u00fd v\u00fdskumn\u00edci zaznamenali, mal amplit\u00fadu pribli\u017ene 0,5 pikotesla, \u010do je ove\u013ea slab\u0161ie ako magnetick\u00e9 pole Zeme. <\/p>\n\n\n\n

Z toho by sa dala vyvodi\u0165 u\u017eito\u010dnos\u0165 biomagnetickej aktivity, ktor\u00e1 by mohla pom\u00f4c\u0165 pri neinvaz\u00edvnej technike detekcie stresu.<\/p>\n\n\n\n

Zlep\u0161enie plod\u00edn je kone\u010dn\u00fdm cie\u013eom na odstr\u00e1nenie \u00fa\u010dinkov sp\u00f4soben\u00fdch environment\u00e1lnymi faktormi, ako s\u00fa zmeny teploty, chemick\u00e9 p\u00f4sobenie a tie\u017e \u00fatok bylino\u017eravcov alebo hmyzu pomocou detekcie elektromagnetickej sp\u00e4tnej v\u00e4zby. Pochvala t\u00edmu za objavenie molekul\u00e1rnej podstaty biomagnetizmu v rastlin\u00e1ch.<\/p>\n\n\n\n
