As a central neural process attention suppresses most of the sensory input while letting through what it deems most important at any certain time, and hence acts as a filter for sensory input. Neuronal mechanisms underlying the coordination of attention have been investigated by using invasive field potential and multiunit recordings as well as with functional magnetic resonance imaging (fMRI). However, less is known of the electrophysiological correlates of the coordination of attention by using magneto- and electroencephalography (MEG and EEG) recordings that record neuronal activity over the whole brain. This study focuses on the neuronal mechanisms of visual attention as investigated by MEG and EEG recordings. Importantly, attentional deficits are central in many brain disorders such as in attention deficit disorder but also affected in several other brain diseases. Hence, understanding the neuronal mechanisms of attention is of central importance to understanding the cognitive deficits in neuropsychiatry.
