　　 Sai ya zama cewa barcin ɗan adam ba tsari ba ne mai tsayuwa kuma a tsaye kamar yadda ake tunani tun asali, ana samun shi ne kawai ta hanyar ci gaba da shigowar abubuwa daban-daban a cikin ƙwaƙwalwa yayin gajiya ko farkawa. Polysomnography ya gano cewa barcin mutane wani tsari ne na lokaci-lokaci da kuma aiki na yau da kullun a cikin matakai daban-daban.

        Dangane da sifofin da aka siffanta electroencephalogram, motsin ido da electromyography, ana iya raba shi kusan zuwa saurin ido Dynamic barci (wanda aka gajarta da REM) da kuma barcin ido mara sauri (wanda aka gajarta a matsayin NREM).

        A cikin matakin barci na REM, ana iya samun motsin ido mai sauri da maras kyau, numfashi da bugun zuciya yana ƙaruwa, hawan jini ya tashi, kuma sautin tsoka yana raguwa; barcin motsin ido mara sauri zai iya kara kasu kashi 1, 2, 3 4.

Kuma barcin REM da barcin da ba na REM ba ya zama yanayin barci, kimanin minti 60-90, kimanin 4-7 irin wannan hawan keke a cikin dare, matasa suna barci dare ɗaya, REM barci yana game da 20% -25%, kuma ba haka ba. -saurin barcin motsin ido ya kai kusan 75% -80%.

        Binciken da aka yi a baya ya gano cewa a matakin barci na REM, ci gaba da yin barci yana samar da gajeren farkawa na lokaci-lokaci, wanda ke da amfani ga jiki don kasancewa a faɗakar da canje-canje a cikin muhallin da ke kewaye da shi, da kuma ƙara haɓakar furotin a cikin jarirai da yara ƙanana, kuma yana da amfani. kula da aikin jijiya a cikin manya.
