Ralph Weidner

PD Dr. Ralph Weidner serves as a researcher at the Jülich Research Centre, specifically within the Institute of Neuroscience and Medicine (INM), where he leads the Cognitive Neuroscience department (INM-3). His work is situated at the intersection of experimental psychology and advanced neuroimaging techniques.

Dr. Weidner's research focuses on understanding how the human brain processes and integrates visual information from our environment. His laboratory investigates the cognitive mechanisms underlying perception and attention, examining how the brain selects relevant information while filtering out irrelevant stimuli. Using a multimodal approach, his team combines experimental psychological paradigms with functional magnetic resonance imaging (fMRI), Dynamic Causal Modeling (DCM), transcranial direct current stimulation (tDCS), and transcranial magnetic stimulation (TMS) to uncover the neural foundations of healthy brain function and potential pathological mechanisms in damaged brains.

His work has significant implications for understanding both normal brain function and neurological disorders where information processing is impaired. The research group maintains strong methodological expertise in functional brain imaging and causal modeling of neural networks, contributing to the broader understanding of how brain structures interact during cognitive processes.
