Evidence of Attenuation in Higher-Level Cognitive Functions
We perceive sensory events as less intense when they are self-generated compared to externally-generated ones. This phenomenon, called attenuation enables us to distinguish sensory events from self and external origins. Results from our novel fMRI paradigm that were just published in the Journal of Neuroscience indicate that attenuation of self-generated stimuli is not limited to sensory consequences but also impact cognitive processes such as numerosity estimations.
Hallucination Research Platform installed at WVU
The Blanke Lab at EPFL is delighted to announce that the WVU Rockefeller Neuroscience Institute (RNI) and Prof. Ali Rezai are now part of the research network investigating hallucinations in Parkinson’s disease. Our robotic device allowing to induce and investigate hallucinations in real-time in patients with Parkinson’s disease has arrived at West Virginia University.
New paper on a mechanism underlying perceptual consciousness
How we perceive the world and ourselves is a major subject of philosophical and scientific enquiry. In a recent study published in Nature Communications we propose that beyond simple cerebral correlates perceptual and self-consciousness involve a common neural mechanism: evidence accumulation.
