Az, hogy a lĂĄtĂłrendszer hogyan kĂŠpes megoldani ezt a feladatot azonban mĂŠg mindig kĂŠrdĂŠs. Az illuzĂłrikus kontĂşrok (IC) agyi feldolgozĂĄsĂĄnak vizsgĂĄlatĂĄval megoldhatĂłnak tĹąnik a problĂŠma. FiziolĂłgiai tanulmĂĄnyok tĂĄmasztjĂĄk alĂĄ a VIĂŠs V2 szerepĂŠt az IC percepciĂłjĂĄban, a magasabb kĂŠrgi terĂźletek szerepĂŠre azonban csak utalĂĄsok vannak, elsĹsorban lĂŠziĂłs vizsgĂĄlatokbĂłl. Jelen tanulmĂĄnyban egysejt regisztrĂĄciĂłs mĂłdszerrel megvizsgĂĄltuk makĂĄkĂł majmoknĂĄl az inferotemporĂĄlis kĂŠreg (IT) szerepĂŠt az IC-k feldolgozĂĄsĂĄban. EredmĂŠnyeink szerint az IT-ben IC-re alakszelektĂv sejtek talĂĄlhatĂłk, ezzel ismĂŠt alĂĄtĂĄmasztottuk az IT szerepĂŠt a formalĂĄtĂĄsban ĂŠs kiterjesztettĂźk azt az illuzĂłrikus kontĂşrok ĂĄltal megalkotott formĂĄkra is. FeltĂŠtelezhetjĂźk, hogy Kanizsa illĂşziĂłk a kĂźlĂśnbĂśzĹ felĂźletek elkĂźlĂśnĂtĂŠsĂŠvel segĂthetnek a hatĂĄrolĂł kontĂşrok azonosĂtĂĄsĂĄban. One of the fundamental aspects of vision is the figure-ground discrimination. However, how the visual system is able to solve this problem is a yet to be answered. It seems that with the help of illusory contours (IC) the problem can be solved. Physiological studies support the role of VI and V2 in the perception of IC, however there are only a few indications about the role of the superior cortical areas from lesion examinations. In the study we examined the role of the inferotemporal cortex (IT) in the processing of the IC-s in macaque monkeys with single-cell recording. We managed to pinpoint IC figure-selective cells in the IT. Our results support the existing theory about the role of the IT in seeing figures, but we extended it to the figures created by the illusory contours too and we assume that the Kanizsa illusions may help in the identification of bordering contours through the separation of different surfaces. %A Csibri PĂŠter %A SĂĄry Gyula %K PszicholĂłgia, LĂĄtĂĄs %S Szegedi pszicholĂłgiai tanulmĂĄnyok %T Az inferotemporĂĄlis kĂŠreg szerepe az illuzĂłrikus kontĂşrok feldolgozĂĄsĂĄban
