Ingabe ubuchopho bethu bulibona ikusasa

Ucwaningo olwenziwa abacwaningi eNyuvesi yaseGlasgow lwafinyelela esiphethweni esithakazelisayo: Ingabe ubuchopho bethu bungakwazi ukubikezela ikusasa?

Lolu cwaningo, olushicilelwe ku-Nature Scientific Reports, lunikeza ukuqonda okujulile kokuthi ubuchopho namehlo kusebenza kanjani komunye nomunye.
UProfessor uye wagada Lars McClei Kulolu cwaningo, ososayensi bezinzwa basebenzise i-fMRI kanye ne-optical illusion ukukhombisa ukuthi ubuchopho bulindele kanjani ulwazi oluzolubona lapho amehlo enyakaza ngokulandelayo. Uyazi, sinyakazisa amehlo ethu izikhathi ezi-4 ngesekhondi futhi lokho kushiya ubuchopho bethu bucubungula lonke lolu lwazi olusha olubukwayo njalo ngama-millisecond angama-250.

• Isitatimende esivela eNyuvesi yaseGlasgow sikubeka ngale ndlela:

Uma kufanele uhambise i-camcorder njalo, imuvi izovela imile. Isizathu esenza sibheke umhlaba njengezinzile kungenxa yezingqondo zethu ezilokhu zicabanga ngekusasa. Ngamanye amazwi, ubuchopho bubikezela ukuthi yini ezoyibona ngemva kokuhambisa amehlo akho.

Ucwaningo luphinde lwembule amandla e-fMRI okufaka isandla kulo mkhakha wocwaningo lwe-neuroscience, njengoba abacwaningi bekwazi ukubona umehluko ekucubunguleni ama-32 m/s kuphela, okusho ukuthi kushesha kakhulu kunalokho okulindele ukuthi kungenzeka kube yi-fMRI.

Futhi njengoba ubonile, ubuchopho bethu bucabanga ngaphambi kokuba sibone izinto. Iqagela ukuthi isizocubungula bese ikwenza ngempela. "Lolu cwaningo lubalulekile ngoba lukhombisa ukuthi i-fMRI inegalelo kanjani kule ndawo yocwaningo lwe-neuroscience," kusho uMcClell. Ngaphezu kwalokho, ukuthola indlela esebenzayo yokusebenza kobuchopho kuyofaka isandla ekwenzeni ikhompuyutha ephefumulelwe ubuchopho nobuhlakani bokwenziwa, futhi kusisize ekutadisheni kwethu ukuphazamiseka kwengqondo.”

Lolu cwaningo belunesihloko esithi "V1 Biomodified Predictive Feedback with Sensory Input". Ixhaswe yisibonelelo se-Biological and Biological Sciences Research Council kanye ne-Human Brain Project. Futhi kuyathakazelisa ngempela ukufunda ngezinto ezinjalo.

Uyabona, ukwaziswa okubonwayo, yiqiniso, kutholwa ngamehlo, kodwa ubuchopho bethu kufanele busebenze ngokushesha kunamehlo ethu. UDkt. Gracie Edwards uthi ulwazi esiluthola ebuchosheni bethu lungaba nomthelela ekuboneni kwethu okokufaka okudluliselwe phambili (ulwazi olubonwayo olucutshungulwa ubuchopho) olusekelwe ezinkumbulo zethu nasezintweni ezivela ezenzakalweni zombono ezifanayo.
