Inference of perceptual priors from path dynamics of passive self-motion

The monitoring of one's own spatial orientation depends on the ability to estimate successive self-motion cues accurately. This process has become to be known as path integration. A feature of sequential cue estimation, in general, is that the history of p ...

Linking perceptual learning with identical stimuli to imagery perceptual learning

Michael Herzog, Lukasz Grzeczkowski, Fred Mast, Elisa Tartaglia

Perceptual learning is usually thought to be exclusively driven by the stimuli presented during training (and the underlying synaptic learning rules). In some way, we are slaves of our visual experiences. However, learning can occur even when no stimuli ar ...

Numerical Priming Between Touch and Vision Depends on Tactile Discrimination

Olaf Blanke, Nathan Quentin Faivre, Roy Salomon, Laurène Véronique Vuillaume

Although the interaction between vision and touch is of crucial importance for perceptual and bodily self-consciousness, only little is known regarding the link between conscious access and tactile processing. Here, we tested whether the numerical encoding ...

The two dimensions of the body representation in women suffering from Anorexia Nervosa

Andrea Serino

A core symptom of Anorexia Nervosa (AN) is a severe alteration of body representations. Evidence from somatoperception studies point to a generic disturbances of somatosensory components of body representations. Here we have investigated whether AN patient ...

Are We Modular Lying Cues Detectors? The Answer Is "Yes, Sometimes"

Christine Mohr, Amer Chamseddine, Vladimir Kopta, Mathieu Arminjon, Aleksandar Paunovic

We quickly form first impressions about newly encountered people guiding our subsequent behaviour (approach, avoidance). Such instant judgments might be innate and automatic, being performed unconsciously and independently to other cognitive processes. Lyi ...

A neuropsychological instrument measuring age-related cerebral decline in older drivers: development reliability, and validity of MedDrive

Michael Herzog, Daniela Herzig, Isabel Cardoso, Paul Vaucher

When facing age-related cerebral decline, older adults are unequally affected by cognitive impairment without us knowing why. To explore underlying mechanisms and find possible solutions to maintain life-space mobility, there is a need for a standardized b ...

Design and Control of a novel Thermo-tactile Multimodal Display

Hannes Bleuler, Simon Gallo

This paper describes the design and control of a water-based multimodal haptic display. The system is able to provide temperature and pressure (pulse) cues through a finger-sized display. Temperature feedback is obtained by mixing hot and cold water stored ...

Membrane potential correlates of sensory perception in mouse barrel cortex

Carl Petersen, Yves Emile Alfred Kremer, Shankar Sachidhanandam, Varun Sreenivasan, Alexandros Kyriakatos

Neocortical activity can evoke sensory percepts, but the cellular mechanisms remain poorly understood. We trained mice to detect single brief whisker stimuli and report perceived stimuli by licking to obtain a reward. Pharmacological inactivation and optog ...

Models of Reward-Modulated Spike-Timing-Dependent Plasticity

Nicolas Frémaux

How do animals learn to repeat behaviors that lead to the obtention of food or other “rewarding” objects? As a biologically plausible paradigm for learning in spiking neural networks, spike-timing dependent plasticity (STDP) has been shown to perform well ...

Paradoxical Evidence Integration in Rapid Decision Processes

Michael Herzog, Wulfram Gerstner, Johannes Rüter, Nicolas Marcille

Decisions about noisy stimuli require evidence integration over time. Traditionally, evidence integration and decision making are described as a one-stage process: a decision is made when evidence for the presence of a stimulus crosses a threshold. Here, w ...
