So, it's vital that we continue to further our understanding of this part of the brain," he said. "Dysfunction in this system causes memory problems and disorientation, such as we see in Alzheimer's disease and age-related decline. Nadasdy is also a researcher at Eötvös Loránd University and the Sarah Cannon Research Institute at St. ![]() "Our research, based on human data, redefines the fundamental properties of the internal coordinate system," said Zoltan Nadasdy, lead author of the study and an adjunct assistant professor in the university's Department of Psychology. The way humans navigate their surroundings and understand their relative position includes an environment-dependent scaling mechanism, an adaptive coordinate system with differences from other mammals, according to the study led by researchers at The University of Texas at Austin. Whereas humans can look at a complex landscape like a mountain vista and almost immediately orient themselves to navigate its multiple regions over long distances, other mammals such as rodents orient relative to physical cues - like approaching and sniffing a wall - that build up over time.
