Karnuka suna mafarki?

Tsarin barci na dabbobinmu yana da kama da na mutane: kamar mutane, karnuka suna da matakan barci na REM (baccin motsin ido da sauri) kuma barci ba tare da saurin motsin ido ba. Wannan yana da mamaki, saboda karnuka suna barci har zuwa sa'o'i 16-18 a rana. A cikin mujallolin "Halayen Jiki" a cikin 1977, masana kimiyya sun buga rahoton da suka yi nazarin ayyukan lantarki na kwakwalwar karnuka shida. Masana kimiyya sun gano cewa karnuka suna ciyar da kashi 21% na barcinsu a cikin barci, 12% a cikin barcin REM, kuma 23% na lokacinsu a cikin barci mai zurfi. Sauran lokacin (44%) karnuka sun farka.

Kawai a lokacin barcin REM a cikin karnuka, fatar ido, tafin hannu, kuma suna iya yin sauti. A wannan lokaci ne manyan abokan mutum suke ganin mafarki.

Matthew Wilson, ƙwararren koyo da ƙwaƙwalwa na MIT, ya fara binciken mafarkin dabba fiye da shekaru 20 da suka gabata. A cikin 2001, ƙungiyar masu bincike karkashin jagorancin Wilson sun gano cewa berayen suna mafarki. Da farko, masanan kimiyya sun yi rikodin ayyukan jijiyoyi na kwakwalwar berayen yayin da suke cikin maze. Sannan sun sami sigina iri ɗaya daga ƙwayoyin cuta a cikin barcin REM. A cikin rabin lokuta, kwakwalwar berayen suna aiki a cikin barcin REM daidai da lokacin da suka shiga cikin maze. Babu kuskure a cikin wannan, tun da sigina daga kwakwalwa sun wuce cikin sauri da ƙarfi kamar lokacin farkawa. Wannan binciken babban bincike ne kuma an buga shi a cikin 2001 a cikin mujallar Neuron.

Don haka, berayen sun bai wa duniyar kimiyyar dalilin yarda cewa duk dabbobi masu shayarwa na iya yin mafarki, wata tambaya ita ce ko suna tunawa da mafarki. Wilson a wani jawabi ma ya ce wannan furci: “Ko da kwari na iya yin mafarki a wani yanayi ko kuma wani.” Irin waɗannan abubuwan suna da ban mamaki, ko ba haka ba?

Bayan haka, Wilson da tawagarsa na masana kimiyya sun fara gwada wasu dabbobi masu shayarwa, ciki har da karnuka.

Binciken barci gabaɗaya ya nuna cewa ƙwaƙwalwa ta kan yi amfani da barci don sarrafa bayanan da aka karɓa a rana. Masanin ilimin halin dan Adam na Harvard Medical School Deirdre Barrett ya fada a wata hira da mujallar People cewa karnuka sun fi yin mafarki ga masu su, kuma hakan yana da ma'ana.

“Babu wani dalili na yarda cewa dabbobi sun bambanta da mu. Domin karnuka sun kasance suna shakuwa da masu su, yana yiwuwa karenka ya yi mafarki game da fuskarka, yana jin kamshin ka, kuma yana jin daɗin jawo maka ƙananan bacin rai,” in ji Barrett. 

Karnuka suna yin mafarki game da damuwarsu ta yau da kullun: za su iya gudu a wurin shakatawa, cin abinci, ko cudanya da sauran dabbobi. Masana kimiyya sun ce sau da yawa karnuka suna mafarkin masu mallakar su: suna wasa da su, suna jin warinsa da magana. Kuma, kamar daidaitattun kwanakin kare, mafarkai na iya zama abin farin ciki, natsuwa, bakin ciki, ko ma ban tsoro.
