Although the amygdala is often directly linked with fear and emotion, amygdala neurons are activated by a wide variety of emotional and non-emotional stimuli. Different subregions within the amygdala may be engaged preferentially by different aspects of emotional and non-emotional tasks. To test this hypothesis, we measured and compared the effects of novelty and fear on amygdala activity. We used high-resolution blood oxygenation level-dependent (BOLD) imaging and streamline tractography to…

Resting-State Amygdala Subregion and Precuneus Connectivity Provide Evidence for a Dimensional Approach to Studying Social Anxiety Disorder
Background: Social anxiety disorder (SAD) is a prevalent and disabling mental health condition, characterized by excessive fear and anxiety in social situations. Resting-state functional magnetic
Parcellation of Human Amygdala Subfields Using Orientation Distribution Function and Spectral K-means Clustering.
High angular and high spatial resolution diffusion magnetic resonance imaging is used to generate orientation distribution function, which bears distinctive microstructural features within amygdala subfields, which is tested on 32 healthy volunteers.
Dynamic Changes in Amygdala Psychophysiological Connectivity Reveal Distinct Neural Networks for Facial Expressions of Basic Emotions
It is found that for each emotion the amygdala recruited a distinctive and spatially distributed set of structures to interact with, and all emotions enhanced amygdala functional integration with premotor cortices compared to neutral faces.
Threat of shock increases excitability and connectivity of the intraparietal sulcus
Anxiety disorders affect approximately 1 in 5 Americans within a given 1 year period, placing a substantial burden on the national health care system, and it is reported that a single brain region, the intraparietal sulcus (IPS), shows both elevated neural activity and global brain connectivity during threat.
Altered hippocampus and amygdala subregion connectome hierarchy in major depressive disorder
The altered role of these limbic subregions in the whole-brain connectome is related to diagnosis and depression severity, contributing to the understanding of the limbic system involvement in MDD and may elucidate the underlying mechanisms of depression.

Neuroimaging Predictors and Mechanisms of Treatment Response in Social Anxiety Disorder: an Overview of the Amygdala
The amygdala and amygdala pathways predict treatment outcome and are altered following treatment, however, further study is needed to establish the role of the amygdala and other candidate regions and brain circuits as sites of action.


Arousal Dissociates Amygdala and Hippocampal Fear Responses: Evidence from Simultaneous fMRI and Skin Conductance Recording
The findings provide direct evidence for a dissociation between human amygdala and hippocampus networks in the visceral experience versus declarative fact processing of fear.
The amygdaloid complex: anatomy and physiology.
The anatomical and physiological substrates proposed to underlie amygdala function are examined, suggesting that long-term synaptic plasticity of inputs to the amygdala underlies the acquisition and perhaps storage of the fear memory.

The connections of the amygdala in rats, cats, and monkeys can be divided into three systems: a largely forebrn system that provides sensory information to the amygdala from the olfactory cortex, ascending taste/visceral pathways, posterior thalamus and sensory association cortex, and a forebrain circuit that seems to be directly involved in emotional behavior and mood.
Processing of the Arousal of Subliminal and Supraliminal Emotional Stimuli by the Human Amygdala
The results provide support for the hypothesis that the left and right amygdalae subserve different functions in emotion processing: the left may decode the arousal signaled by the specific stimulus, whereas the right may provide a global level of autonomic activation triggered automatically by any arousing stimulus.

Resting-state connectivity of the amygdala is altered following Pavlovian fear conditioning
Resting-state data show that amygdala connectivity is altered following Pavlovian fear conditioning and that these changes are also related to behavioral outcomes, which may reflect the operation of a consolidation process that strengthens neural connections to support memory after the learning event.
