Functional Neuroanatomy of Emotion: A Meta-Analysis of Emotion Activation Studies in PET and fMRI

  author={K. Luan Phan and Tor D. Wager and Stephan F. Taylor and Israel Liberzon},
Neuroimagingstudies with positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) have begun to describe the functional neuroanatomy of emotion. Taken separately, specific studies vary in task dimensions and in type(s) of emotion studied and are limited by statistical power and sensitivity. By examining findings across studies, we sought to determine if common or segregated patterns of activations exist across various emotional tasks. We reviewed 55 PET and fMRI…

Functional Neuroimaging Studies of Human Emotions

Observations in several regions of interest in limbic and paralimbic brain regions in emotional responding are reviewed, to determine if common or segregated patterns of activations exist in different emotions and across various emotional tasks.

Functional neuroanatomy of emotions: A meta-analysis

Novel statistical techniques were applied to the meta-analysis of 106 PET and fMRI studies of human emotion and predictions made by key neuroscientific models demonstrated partial support for asymmetry accounts.

fMRI of Emotion

Recent brain imaging work has expanded our understanding of the mechanisms of perceptual, cognitive, and motor functions in human subjects, but research into the cerebral control of emotional and

The neural correlates of happiness: A review of PET and fMRI studies using autobiographical recall methods

This article reviews eight positron emission tomography and seven functional magnetic resonance imaging studies that have investigated happiness by using autobiographical recall to induce emotion and integrates these findings, discussing important limitations of the extant literature and suggesting new research directions.

Neural Correlates of Levels of Emotional Awareness: Evidence of an Interaction between Emotion and Attention in the Anterior Cingulate Cortex

This work used positron emission tomography and 15O-water to measure cerebral blood flow in healthy women during film- and recall-induced emotion and correlated CBF changes attributable to emotion with subjects' scores on the Levels of Emotional Awareness Scale (LEAS), a measure of individual differences in the capacity to experience emotion in a differentiated and complex way.

Neuroanatomical correlates of externally and internally generated human emotion.

This study identified brain regions that participate in externally and internally generated human emotion, suggesting that these regions participate in aspects of emotion that do not depend on the nature of the emotional stimulus.

The Emotional Modulation of Cognitive Processing: An fMRI Study

Results provide evidence that the emotional valence and arousing nature of stimuli used during the performance of an attention-demanding cognitive task are reflected in discernable, quantitative changes in the functional anatomy associated with task performance.

Neuroanatomical correlates of happiness, sadness, and disgust.

This study identifies regions of the brain that participate in happiness, sadness, and disgust, regions that distinguish between positive and negative emotions, and regions that depend on both the elicitor and valence of emotion or their interaction.

Imaging Cognition II: An Empirical Review of 275 PET and fMRI Studies

Analysis of regional activations across cognitive domains suggested that several brain regions, including the cerebellum, are engaged by a variety of cognitive challenges.

Emotional arousal and activation of the visual cortex: an fMRI analysis.

Functional activity in the visual cortex was assessed using functional magnetic resonance imaging technology while participants viewed a series of pleasant, neutral, or unpleasant pictures. Coronal

The functional neuroanatomy of major depression: an fMRI study using an emotional activation paradigm

An fMRI study using an emotional activation paradigm revealed that passive viewing of the emotionally laden film clip produced a significantly greater activation in the left medial prefrontal cortex and in the right cingulate gyrus in depressed patients than in normal control subjects.
