The phenomenon, described in a sentence: “Certain visual displays are not perceived in a stable way but, from time to time and seemingly spontaneously, their appearance wavers and settles in a distinctly different form.”[37] A final example of university commitment to cognitive biology can be found at Comenius University in Bratislava, Slovakia. There in the Faculty of Natural Sciences, the Bratislava Biocenter is presented as a consortium of research teams working in biomedical sciences. Their website lists the Center for Cognitive Biology in the Department of Biochemistry at the top of the page, followed by five lab groups, each at a separate department of bioscience.
