Body Context and Posture Affect Mental Imagery of Hands

Olaf Blanke, Bogdan Draganski, Silvio Ionta

Different visual stimuli have been shown to recruit different mental imagery strategies. However the role of specific visual stimuli properties related to body context and posture in mental imagery is still under debate. Aiming to dissociate the behavioura ...

Electrical neuroimaging of memory discrimination based on single-trial multisensory learning

Micah Murray, Antonia Thelen

Multisensory experiences influence subsequent memory performance and brain responses. Studies have thus far concentrated on semantically congruent pairings, leaving unresolved the influence of stimulus pairing and memory sub-types. Here, we paired images w ...

Neuroscience robotics to investigate multisensory integration and bodily awareness

Olaf Blanke, Dominique Chapuis, Roger Gassert, Roberto Martuzzi, Silvio Ionta, Christian Pfeiffer, Julio Duenas

Humans experience the self as localized within their body. This aspect of bodily self-consciousness can be experimentally manipulated by exposing individuals to conflicting multisensory input, or can be abnormal following focal brain injury. Recent technol ...

Perceptual Learning, Roving and the Unsupervised Bias

Michael Herzog, Wulfram Gerstner, Aaron Michael Clarke

Perceptual learning is reward-based. A recent mathematical analysis showed that any reward-based learning system can learn two tasks only when the mean reward is identical for both tasks [Frémaux, Sprekeler and Gerstner, 2010, The Journal of Neuroscience, ...

Stress effects on working memory, explicit memory, and implicit memory for neutral and emotional stimuli in healthy men

Maria del Carmen Sandi Perez

Stress is a strong modulator of memory function. However, memory is not a unitary process and stress seems to exert different effects depending on the memory type under study. Here, we explored the impact of social stress on different aspects of human memo ...

Perceptual and semantic contributions to repetition priming of environmental sounds

Roberto Martuzzi, Stephanie Clarke

Repetition of environmental sounds, like their visual counterparts, can facilitate behavior and modulate neural responses, exemplifying plasticity in how auditory objects are represented or accessed. It remains controversial whether such repetition priming ...

EEG-MEG evidence for early differential repetition effects for fearful, happy and neutral faces

Nathalie George, Manuel Mercier

To deter-mine how emotional information modulates subsequent traces for repeated stimuli, we combined simultaneous electro-encephalography (EEG) and magneto-encephalography (MEG) measures during long-lag incidental repetition of fearful, happy, and neutral ...

Long-lasting modulation of feature integration by transcranial magnetic stimulation

Michael Herzog, Frank Scharnowski, Johannes Rüter

The human brain analyzes a visual object first by basic feature detectors. On the objects way to a conscious percept, these features are integrated in subsequent stages of the visual hierarchy. The time course of this feature integration is largely unknown ...

Dynamic I-V curves are reliable predictors of naturalistic pyramidal-neuron voltage traces

Wulfram Gerstner, Carl Petersen, Laurent Badel, Sandrine Lefort, Romain Brette

Neuronal response properties are typically probed by intracellular measurements of current-voltage (I-V) relationships during application of current or voltage steps. Here we demonstrate the measurement of a novel I-V curve measured while the neuron exhibi ...

Analysis of taste processing in rat gustatory cortex

Riccardo Accolla

Gustatory perception is a complex phenomenon involving the recognition of sensory properties of a food (taste modality and intensity, flavour, texture, fat content, temperature) as well as its reward value (pleasantness and nutritional value). The sense of ...
