Da yake tsokaci game da labarin Edward Boyden, Ben Barres, Shugaban Sashen Nazarin Halittar Jiki & Glial Cell Biology na Faculty na 1000 kuma Farfesa a Makarantar Magunguna ta Jami'ar Stanford ya ce: "Wataƙila za a sami lambar yabo ta Nobel ga optogenetics wata rana kamar yadda ta kawo sauyi ga ƙoƙarinmu na Wannan labarin yana ba da haske mai ban sha'awa game da haihuwar optogenetics da kuma matsayin manyan 'yan wasa."

Ƙirƙirar optogenetics a zahiri yana ba da haske kan yadda kwakwalwarmu ke aiki. An buga shi a cikin fitowar Mayu 2011 na F1000 Biology Reports, labarin da Edward Boyden ya bayyana ya ba da hangen nesa na musamman game da haihuwar kayan aikin optogenetics, sabbin albarkatu don yin nazari da da'irar kwakwalwar injiniya. Waɗannan 'kayan aikin' suna ɗaukar nau'ikan ƙwayoyin halitta waɗanda, lokacin da aka yi niyya ga takamaiman ƙwayoyin cuta a cikin kwakwalwa, suna ba da damar aikin su ya motsa ko kuma ya yi shiru da haske, ta haka yana bayyana yadda gabaɗayan hanyoyin jijiyoyi ke aiki.
