Central psychophysiology

We register, sense and perceive information that is reaching us from our environment. How we process this information is subject to certain regularities and principles, that have been studied for over a century. Today, we examine the principles of perception using psychophysics and analyze the underlying neural mechanisms using EEG. Perception involves multiple processing stages, and therein, oscillatory neural activity plays an important role: Event-related activity tells us much about the processing cascade involved in stimulus processing. Ongoing neural oscillations represent the functional state of the brain, as well as emotional and cognitive processes. Moreover, they influence perception.
