HEIDELBERG, Germany, Gumiguru 4, 2021 - Maitiro akagadzirwa nePedvedel Group kuEuropean Molecular Biology Laboratory (EMBL) inobvumidza maurosayendisiti kucherechedza mauroni anorarama mukati-kati mehuropi - kana chero chero sero rakavanzwa mukati meshungu. Iyo nzira yakavakirwa pane matatu-photon microscopy uye adaptive optics.

Maitiro acho anowedzera kugona kwemasayendisiti ekucherechedza maastroscyte anogadzira calcium yakazunguzirwa mumativi akadzika eecortex, uye kuona chero mamwe maseru enural mune hippocampus, iyo nzvimbo yehuropi inoitisa nzvimbo yekurangarira uye kufamba. Izvo zvinoitika zvinoitika nguva zhinji muhuropi hwezvipenyu zvese zvipenyu. Lina Streich weboka rePedvedel nevamwe vake vakakwanisa kushandisa nzira iyi kutora ruzivo rwakanaka rwemaseru aya akasiyana-siyana zvisati zvamboitika.
Girazi rakaremara rinoshandiswa mu microscopy kutarisisa mwenje mukati mehupenyu mhenyu. Kutendeseka kwaIsabel Romero Calvo, EMBL.

Mune neuroscience, matishu ehuropi anowanzoonekwa mune zvidiki zvemhando dzemhando kana mune ex vivo sampu dzinoda kuchekwa kuti zvionekwe - ese ari maviri anomiririra mamiriro asiri ezvepanyama. Zvakajairika maseru ehuropi chiitiko chinoitika chete mumhuka mhenyu. Iyo mbeva uropi, zvisinei, inhengo inopararira zvakanyanya, akadaro Robert Prevedel. "Muuropi idzi, mwenje haugone kutariswa zviri nyore, nekuti unobatana nezvikamu zvemagetsi," akadaro. “Izvi zvinogumira pakudzika kwaungaita mufananidzo wakatsetseka, uye zvinoita kuti zvive zvakaoma zvikuru kutarisa pazvivakwa zvidiki zvakadzika mukati mehuropi nemaitiro echinyakare.

“Nemaitiro echinyakare emicroscopy echinyakare, mafoni maviri anonwiwa nemolekisheni ye fluorescence nguva dzese, uye iwe unogona kuve nechokwadi chekuti kunakidzwa kunokonzerwa nemwaranzi kwakadzikira kuita vhoriyamu diki. Asi kana mafotoni achienda kure, ndipo paanonyanya kurasika nekuda kwekupararira. ”

Imwe nzira yekukunda izvi ndeyokuwedzera hurefu hwemapikicha anonakidza akananga kune infrared, izvo zvinoita kuti simba remwaranzi rikwane rakabatwa ne fluorophore. Pamusoro pezvo, kushandisa mafotoni matatu pachinzvimbo chemaviri kunogonesa mifananidzo yakajeka kuti iwanikwe mukati mukati mehuropi. Rimwe dambudziko rakaramba riripo, zvakadaro: kuve nechokwadi chekuti mafotoni akatarisa, kuitira kuti mufananidzo wese usanyanye.
