Studien dreide seg om identifisering av molekyler som regulerte signalet.<\/p>\n\n\n\n<p>TANKEN BAK FORSKNINGEN<\/p>\n\n\n\n<p>Synapses are the junction where the electrical signals are transmitted between the nerve cells. <\/p>\n\n\n\n<p>These electrical signals are converted into chemical neurotransmitters by the brain that travels through synaptic gaps. The team described how the shapes of electrical signals benefit the functioning of synapses. <\/p>\n\n\n\n<p>Nevronene som aktiveres under nevrotransmisjonen, har forskjellige m\u00f8nstre. <\/p>\n\n\n\n<p>Disse endringene i form og antall f\u00f8rer til at synapsene styrkes eller svekkes (ogs\u00e5 kjent som synaptisk plastisitet). <\/p>\n\n\n\n<p>N\u00e5r hjernecellene i begge ender av synapsen kontinuerlig utveksler kjemiske signaler, oppst\u00e5r langtidspotensiering (LTP). <\/p>\n\n\n\n<p>Denne LTP-en forbedrer signalene mellom celler og synapser, og f\u00f8rer ogs\u00e5 til at synapsene blir sterkere. Denne LTP er grunnlaget for l\u00e6ring og hukommelse i hjernen p\u00e5 et sted som kalles hippocampus.<\/p>\n\n\n\n<p>Forskerne fokuserte studien sin p\u00e5 hippocampus-omr\u00e5det i hjernen. De fant ut at signalene som ble overf\u00f8rt over synapsen i dette omr\u00e5det, var analoge. <\/p>\n\n\n\n<p>Teamet oppdaget at de elektriske signalene eller \"piggene\" ble levert i form av analoge signaler og ikke digitale signaler. <\/p>\n\n\n\n<p>Denne oppdagelsen banet vei for en klarere forst\u00e5else av mekanismen. Disse analoge signalene gjorde det lettere \u00e5 regulere styrken i hjernekretsen.<\/p>\n\n\n\n<p>The molecule regulating these electrical signals was also found. The molecule Kv\u03b21 widened the presynaptic action. <\/p>\n\n\n\n<p>Dette molekylet regulerer ikke bare kaliumstr\u00f8mmen, men bidrar ogs\u00e5 til \u00e5 forme de elektriske signalene. <\/p>\n\n\n\n<p>When they previously carried out the experiment, they excluded the Kv\u03b21 molecule in the mice. Soon the results showed an opposite reaction, there was a drastic impact on the sleep and memory cycle of the mice. <\/p>\n\n\n\n<p>Dette bekreftet den positive virkningen som molekylet utf\u00f8rte i systemet.<\/p>\n\n\n\n<p>I tillegg avdekker forskningen deres ogs\u00e5 hvordan \u00e9n enkelt elektrisk impuls kan transportere flere informasjonsbiter, noe som gir mer kontroll over lavfrekvente signaler. <\/p>\n\n\n\n<p>Dette betyr at hjernen v\u00e5r er langt mer effektiv enn man kan forestille seg. Teknisk sett utf\u00f8rer hjernen v\u00e5r superdatabehandlingsoppgaver ved lav elektrisk signalering. <\/p>\n\n\n\n<p>Forskningen deres gjorde det mulig \u00e5 m\u00e5le spenningen og nevrotransmitteren ved hjelp av lys, som i sin tur m\u00e5lte de elektriske signalene i de synaptiske forbindelsesstedene. <\/p>\n\n\n\n<p>Dette endret b\u00e5de perspektivet og utvidet forskningsfeltet n\u00e5r det gjelder molekyl\u00e6re regulatorer som spiller en viktig rolle i hjerneaktiviteten.<\/p>\n\n\n\n<p>This discovery enables a whole new path for pharmaceuticals. This could lead to the findings of new drug delivery in case of dementia or Alzheimer&#8217;s. <\/p>\n\n\n\n<p>Molecular regulators could be the key to utilizing the complete brain capacity. Many neurological diseases could be cured if the right brain metabolism pathway is found. <\/p>\n\n\n\n<p>Det sies at l\u00e6ring aldri utt\u00f8mmer sinnet, det er en kraft som kan forandre verden. Denne oppdagelsen f\u00f8rer utvilsomt til et helt nytt niv\u00e5 av l\u00e6ring og kraft til \u00e5 holde fast ved den.<\/p>\n\n\n\n<p>For \u00e5 f\u00e5 vite mer om forskningen deres, sjekk ut referansen nedenfor.<\/p>\n\n\n\n<p>Referanse :<\/p>\n\n\n\n<p>In Ha Cho, Lauren C.
