Physical Body Orientation Impacts Virtual Navigation Experience and Performance
Olaf Blanke, Emanuela De Falco, Hsin-Ping Wu, Hyukjun Moon
Most human navigation studies in MRI rely on virtual navigation. However, the necessary supine position in MRI makes it fundamentally different from daily ecological navigation. Nonetheless, until now, no study has assessed whether differences in physical ...
Washington2023Sense of self impacts spatial navigation and hexadirectional coding in human entorhinal cortex
Olaf Blanke, Nathan Quentin Faivre, Hyeongdong Park, Baptiste Gauthier, Hyukjun Moon
Grid cells in entorhinal cortex (EC) encode an individual’s location in space and rely on environmental cues and self-motion cues derived from the individual’s body. Body-derived signals are also primary signals for the sense of self and based on integrate ...
2022Bodily self and human grid cell-like activity: probing spatial representation with immersive virtual reality
Grid cells are place-modulated neurons that encode the location of an agent in space, relying on the integration of various sensorimotor signals from the body. Of note, the integration of those signals is also fundamental for the agent's conscious experien ...
EPFL2021Impaired cognitive flexibility and heightened urgency are associated with increased alcohol consumption in rodent models of excessive drinking
Alcohol use disorder (AUD) is characterized by impairments in decision-making that can exist as stable traits or transient states. Cognitive inflexibility reflects an inability to update information that guides decision-making and is thought to contribute ...
WILEY2021Imagining with and in Space: Structural support as a cognitive device in architectural education
Dieter Dietz, Julien Lafontaine Carboni, Aurélie Dupuis, Darío Negueruela Del Castillo
In this paper, we will argue that the structure of the spatio-temporal pedagogical set-up and the elaboration of an evolutionary support for operations of cognition and imagination are powerful in transforming learning cultures. We develop this argument in ...
2020Interactions of spatial strategies producing generalization gradient and blocking: A computational approach
Ricardo Andres Chavarriaga Lozano
We present a computational model of spatial navigation comprising different learning mechanisms in mammals, i.e., associative, cognitive mapping and parallel systems. This model is able to reproduce a large number of experimental results in different varia ...
2018A generalised framework for detailed classification of swimming paths inside the Morris Water Maze
Maria del Carmen Sandi Perez, Eleni Vasilaki
The Morris Water Maze is commonly used in behavioural neuroscience for the study of spatial learning with rodents. Over the years, various methods of analysing rodent data collected during this task have been proposed. These methods span from classical per ...
2018CAR-Net: Clairvoyant Attentive Recurrent Network
We present an interpretable framework for path prediction that leverages dependencies between agents' behaviors and their spatial navigation environment. We exploit two sources of information: the past motion trajectory of the agent of interest and a wide ...
2018Evidence for eligibility traces in human learning
Michael Herzog, Wulfram Gerstner, Kerstin Preuschoff, Marco Philipp Lehmann, He Xu, Vasiliki Liakoni
Whether we prepare a coffee or navigate to a shop: in many tasks we make multiple decisions before reaching a goal. Learning such state-action sequences from sparse reward raises the problem of credit-assignment: which actions out of a long sequence should ...
arXiv2017Not all anxious individuals get lost: trait anxiety and mental rotation ability interact to explain performance in map-based route learning in men
Maria del Carmen Sandi Perez, John Christian Thoresen, Rebecca Francelet
Navigation through an environment is a fundamental human activity. Although group differences in navigational ability are documented (e.g., gender), little is known about traits that predict these abilities. Apart from a well-established link between menta ...
