Meta-analysis of Functional Neuroimaging of Major Depressive Disorder in Youth
Abstract
Despite its high prevalence and morbidity, the underlying neural basis of major depressive disorder (MDD) in youth is not well understood. To identify in youth diagnosed as having MDD the most reliable neural abnormalities reported in existing functional neuroimaging studies and characterize their relations with specific psychological dysfunctions. Searches were conducted in PubMed and Web of Science to identify relevant studies published from November 2006 through February 2015. The current analysis took place from August 21, 2014, to March 28, 2015. We retained articles that conducted a comparison of youth aged 4 to 24 years diagnosed as having MDD and age-matched healthy controls using task-based functional magnetic resonance imaging and a voxelwise whole-brain approach. We extracted coordinates of brain regions exhibiting differential activity in youth with MDD compared with healthy control participants. Multilevel kernel density analysis was used to examine voxelwise between-group differences throughout the whole brain. Correction for multiple comparisons was performed by computing null hypothesis distributions from 10 000 Monte Carlo simulations and calculating the cluster size necessary to obtain the familywise error rat...Continue Reading

Brain Circuits in Emotional Learning
The neuronal circuits within the cortico-limbic brain regions form networks that mediate emotional behavior. Areas specific to emotional learning include the basal amygdala and sublenticular extended amygdala region along with a supplemental motor area.
