. ▁For ▁example , ▁dis ruption ▁of ▁the ▁interaction ▁between ▁In a C , ▁the ▁protein ▁kin ase ▁C , ▁and ▁In a D ▁results ▁in ▁a ▁delay ▁in ▁in activ ation ▁of ▁the ▁light ▁response . ▁ ▁Un like ▁verte br ate ▁met ar hod ops in , ▁in verte br ate ▁met ar hod ops in ▁can ▁be ▁converted ▁back ▁into ▁rh od ops in ▁by ▁absor bing ▁a ▁phot on ▁of ▁orange ▁light ▁( 5 8 0   nm ). ▁ ▁About ▁two - third s ▁of ▁the ▁D ros oph ila ▁brain ▁is ▁dedicated ▁to ▁visual ▁processing . ▁Although ▁the ▁spatial ▁resolution ▁of ▁their ▁vision ▁is ▁significantly ▁worse ▁than ▁that ▁of ▁humans , ▁their ▁temporal ▁resolution ▁is ▁around ▁ 1 0 ▁times ▁better . ▁ ▁Gro oming ▁ ▁D ros oph ila ▁are ▁known ▁to ▁exhib it ▁gro oming ▁behav iors ▁that ▁are ▁executed ▁in ▁a ▁predict able ▁manner . ▁D ros oph ila ▁consist ently ▁begin ▁a ▁gro oming ▁sequence ▁by ▁using ▁their ▁front ▁legs ▁to ▁clean ▁the ▁eyes , ▁then ▁the ▁head ▁and ▁anten na e . ▁Using ▁their ▁h ind ▁legs , ▁D ros oph ila ▁proceed ▁to ▁gro om ▁their ▁ab d omen , ▁and ▁finally ▁the ▁wings ▁and ▁thor ax . ▁Through out ▁this ▁sequence , ▁D ros oph ila ▁period ically ▁rub ▁their ▁legs ▁together ▁to ▁get ▁rid ▁of ▁excess ▁dust ▁and ▁de br is ▁that ▁accum ul ates ▁during ▁the ▁gro oming ▁process . ▁ ▁Gro oming ▁behav iors ▁have ▁been ▁shown
