Kodi agalu amalota?

Magonedwe a ziweto zathu ndi ofanana kwambiri ndi a anthu: monga anthu, agalu amakhala ndi magawo a kugona kwa REM (kugona kwamaso mwachangu) ndikugona popanda kuyenda mwachangu. Izi zikuwoneka zodabwitsa, chifukwa agalu amagona mpaka maola 16-18 pa tsiku. M'magazini yotchedwa "Physiological Behavior" mu 1977, lipoti linasindikizidwa ndi asayansi omwe anaphunzira ntchito yamagetsi ya ubongo wa agalu asanu ndi limodzi. Asayansi apeza kuti agalu amathera 21% akugona m'tulo, 12% akugona REM, ndipo 23% ya nthawi yawo akugona tulo tofa nato. Nthawi yotsalayo (44%) agalu anali maso.

Kungotsala pang'ono kugona kwa REM mwa agalu, zikope, paws kunjenjemera, ndipo amatha kupanga phokoso. Ndi mu gawo ili pamene mabwenzi apamtima a munthu amawona maloto.

Matthew Wilson, katswiri wophunzirira ndi kukumbukira wa MIT, adayamba kufufuza maloto a nyama zaka zoposa 20 zapitazo. Mu 2001, gulu la ofufuza motsogozedwa ndi Wilson adapeza kuti makoswe amalota. Choyamba, asayansi adalemba ntchito za ubongo wa makoswe pamene amadutsa mumsewu. Kenako adapeza zizindikiro zomwezo kuchokera ku ma neuron mu kugona kwa REM. Mu theka la milandu, ubongo wa makoswe umagwira ntchito mu kugona kwa REM mofanana ndi pamene iwo anadutsa mumsewu. Panalibe kulakwitsa pamenepa, chifukwa zizindikiro zochokera muubongo zinkadutsa pa liwiro lofanana ndi la kudzuka. Phunziroli linali lodziwika bwino ndipo linasindikizidwa mu 2001 mu magazini ya Neuron.

Motero, makoswe anapatsa dziko la sayansi chifukwa chokhulupirira kuti nyama zonse zoyamwitsa zimatha kulota, funso lina ndi lakuti kaya zimakumbukira maloto. Wilson anafika ponena mawu akuti: “Ngakhale ntchentche zimatha kulota m’njira zosiyanasiyana.” Mfundo zimenezi n’zodabwitsa, si choncho?

Pambuyo pake, Wilson ndi gulu lake la asayansi anayamba kuyesa zinyama zina, kuphatikizapo agalu.

Kafukufuku wa tulo akuwonetsa kuti nthawi zambiri ubongo umagwiritsa ntchito kugona kuti usinthe zomwe walandira masana. Katswiri wa zamaganizo ku Harvard Medical School, Deirdre Barrett, pokambirana ndi magazini ya People kuti agalu amatha kulota eni ake, ndipo izi ndi zomveka.

“Palibe chifukwa chokhulupirira kuti nyama ndi zosiyana ndi ife. Chifukwa agalu amakonda kukhala okonda eni ake, nthawi zambiri galu wanu amalota za nkhope yanu, amakununkhirani, komanso amasangalala kukukhumudwitsani pang'ono," akutero Barrett. 

Agalu amalota nkhawa zawo zanthawi zonse: amatha kuthamanga kupaki, kudya zakudya zabwino, kapena kukumbatirana ndi ziweto zina. Asayansi amanena kuti nthawi zambiri agalu kulota eni ake: iwo kusewera nawo, kumva fungo lake ndi kulankhula. Ndipo, monga masiku agalu wamba, maloto amatha kukhala osangalatsa, odekha, achisoni, kapena owopsa.

Galu wanu amatha kukhala ndi maloto owopsa ngati ali wovuta, akudandaula kapena akukulira m'tulo. Komabe, akatswiri ambiri samalimbikitsa kudzutsa chiweto chanu panthawiyi, chikhoza kuchita mantha. Ngakhale anthu pambuyo pa maloto ena amafunika mphindi zochepa kuti azindikire kuti malotowo anali ongopeka chabe ndipo tsopano ali otetezeka.

Kodi chiweto chanu chimachita bwanji pogona? Kodi mukuganiza kuti amalota chiyani?
