Brain activation to emotional words in depressed vs healthy subjects

Brain activation to emotional words in depressed vs healthy subjects.

Depression involves either enhanced processing of negative stimuli or diminished processing of positive stimuli. We used functional magnetic resonance imaging to assess brain activation in depressed vs healthy participants. Fifteen participants diagnosed with major depressive disorder and 15 controls were scanned during a lexical decision task involving neutral, happy, sad, and threat-related w...

Determining the relationship between depression and brain waves in depressed subjects using Pearson correlation and regression

Background and aims: The aim of this study was to investigate the relationship between brain waves and Beck Depression Inventory(BDI) score in clinical cases with depression. Methods: In this study, EEG was taken using neurofeedback device at the point F4 of dorsolateral prefrontal cortex (DLPFC) of the brain of 60 depressed patients referred to psychiatr...

Pre-Activation Negativity (PrAN) in Brain Potentials to Unfolding Words

We describe an event-related potential (ERP) effect termed the "pre-activation negativity" (PrAN), which is proposed to index the degree of pre-activation of upcoming word-internal morphemes in speech processing. Using lexical competition measures based on word-initial speech fragments (WIFs), as well as statistical analyses of ERP data from three experiments, it is shown that the PrAN is sensi...

Brain-Behavioral Systems in Patients with Comorbid Anxiety -Depression vs. Healthy Individuals

Background: According to the brain-behavioral systems theory, behavioral inhibition and behavioral activation systems contribute to the development of many psychopathological conditions. Given that anxiety and depression are the most common emotional disorders and the fact that they are highly overlapping, the aim of this study was to compare the brain-behavioral systems in the...
