Functional significance of delta oscillations is not fully understood. One way to approach this
question would be from an evolutionary perspective. Delta oscillations dominate the EEG of …

Olfactory and emotional higher processing pathways share common anatomical substrates.
Hence, depression is often accompanied by alterations in olfactory function. These …

Biological markers for depression are of great interest to aid in elucidating the causes of
major depression. We assess currently available biological markers to query their validity for …

Individuals with current depression show reduced amplitude of the P300 component of the
stimulus‐locked event‐related potential (ERP)—an effect most often examined in oddball …

BackgroundReward dysfunction is a major dimension of depressive symptomatology, but it
remains obscure if that dysfunction varies across different reward types. In this study, we …

Neurocognitive impairments commonly observed in depressive disorders are thought to be
reflected in reduced P300 amplitudes. To date, depression‐related P300 amplitude …

Background: Previous research has found deficits in both the reward positivity (RewP) and
P300 components of the event-related potential (ERP) in relation to depression. The current …

Abstract Changes in EEG have been reported in both major depressive disorder (MDD) and
bipolar disorder (BD). Specifically, power changes in EEG alpha and theta frequency bands …

Background: Alterations in P300 components occur in depressed patients, but the brain
regions contributing to these changes remain unclear. Aims: Thus, the aim of the present …

Individuals who have a depressive disorder commonly experience difficulties with
concentration, attention, and other cognitive functions, such as memory and executive …
