The P300 component decreases in a bimodal oddball task in individuals with depression: An event-related potentials study

Event-related potentials (ERPs) are electroencephalogram (EEG) indexes that allow for non-invasive recordings of cerebral activity with a temporal resolution on the order of milliseconds (Boutros et al., 2011). Such recordings may also allow for further identification of the relationship between neural activity and stimulus processing, each of which may be abnormal in individuals with psychiatric disorders (Charney and Nestler, 2008). Many studies have attempted to identify distinct ERP properties of specific cognitive functions or processes, most frequently reporting on the P300 component (Hansenne,2006).
