 Bincike 
Aikin farko ya mayar da hankali kan gano da kuma fayyace filayen riba na cortical, ƙa'idar lissafi mai yawa da wurare da yawa na cortex ke amfani da su.   Andersen da Zipser na UCSD sun haɓaka ɗaya daga cikin samfuran hanyar sadarwa ta jijiyoyi na farko na aikin cortical, wanda ya samar da tushen lissafi don gwada hasashe bisa ga binciken dakin gwaje-gwaje.  Bincikensa ya tabbatar da cewa cortex na baya (PPC) yana da hannu wajen ƙirƙirar manufofin motsi - shirye-shiryen farko da na ɓoye don motsi.  A baya, ana tunanin wannan ɓangaren kwakwalwa kawai yana aiki ne don wayar da kan jama'a game da sararin samaniya da kulawa. Dakin gwaje-gwajensa ya gano yankin intraparietal na gefe (LIP) a cikin PPC kuma ya kafa rawar da yake takawa a cikin motsin ido.  Ya kuma gano yankin isa parietal, wani yanki da ke da hannu wajen ƙirƙirar tsare-tsaren isa da wuri.  Dakin gwaje-gwajensa ya kuma yi wasu bincike da suka shafi fahimtar motsi na gani. Ya tabbatar da cewa yankin tsakiya na lokaci yana sarrafa fahimtar tsari daga motsi.  Ya gano cewa ana ƙididdige fahimtar alkiblar tafiya, mai mahimmanci ga kewayawa, a cikin kwakwalwa ta amfani da abubuwan da ke motsa gani da kuma siginar motsin ido.  Dakin gwaje-gwajensa ya kuma ƙayyade yadda ake haɗa siginar matsayin ido da gaɓoɓi don daidaita ido da hannu. 

A cikin 'yan shekarun nan ya faɗaɗa bincikensa zuwa nazarin fassara. Ƙungiyarsa ta tabbatar da cewa siginar niyya daga PPC za a iya amfani da ita azaman siginar sarrafawa ga robar jijiya.  Roba na jijiya na iya taimaka wa marasa lafiya da suka shanye ta hanyar yin rikodin siginar kwakwalwarsu, fassara su, sannan kuma su ba su damar amfani da waɗannan siginar da aka sarrafa don sarrafa na'urori na waje, kamar ƙafafun robot, kwamfutoci ko kekunan guragu kawai suna amfani da su ta hanyar tunani game da shi.
