Visual cognition at the Berlin School of Mind and Brain
From 2009 till 2015, Niko Busch was a Professor at Charité - Universitätsmedizin Berlin, mainly funded by the Berlin School of Mind and Brain Excellence Initiative grant.
His research focused on visual cognition: perception, attention and memory. The group used behavioral methods, psychophysics, and electroencephalographic (EEG) recordings in humans for most of our experiments.
Spontaneous EEG oscillations
By far the most studies in cognitive neuroscience have studied how the brain responds to experimental events. These studies have revealed how information processing in the brain is determined by external input. But the brain is not just a passive receiver of information; the brain continuously generates its own internal processes, and any input from outside the brain interacts with this spontaneous internal context.
Oscillations are ubiquitous in electrical recordings of spontaneous brain activity. Most prominent are oscillations in the alpha and theta frequency range. We combined time-frequency analysis of EEG data and visual psychophysics to find out how amplitude and phase of these signals are related to perception and attention.
