MEG evidence for dynamic amygdala modulations by gaze and facial emotions.

PLoS ONE, 2013
BackgroundAmygdala is a key brain region for face perception. While the role of amygdala in the perception of facial emotion and gaze has been extensively highlighted with fMRI, the unfolding in time of amydgala responses to emotional versus neutral ...

Robust automated amygdala segmentation via multi-atlas diffeomorphic registration

Frontiers in Neuroscience, 2012
Here, we describe a novel method for volumetric segmentation of the amygdala from MRI images collected from 35 human subjects. This approach is adapted from open-source techniques employed previously with the hippocampus (Suh et al., 2011; Wang et al ...

Associations between early trajectories of amygdala development and later school-age anxiety in two longitudinal samples

Developmental Cognitive Neuroscience
Amygdala function is implicated in the pathogenesis of autism spectrum disorder (ASD) and anxiety. We investigated associations between early trajectories of amygdala growth and anxiety and ASD outcomes at school age in two longitudinal studies: high ...

Processing of the Arousal of Subliminal and Supraliminal Emotional Stimuli by the Human Amygdala [PDF]

, 2003
The amygdala is known to play an important role in conscious and unconscious processing of emotional and highly arousing stimuli. Neuroanatomical evidence suggests that the amygdala participates in the control of autonomic responses, such as skin ...

Sex differences in maturational timing of amygdala and prefrontal cortex volumes and white matter tract microstructure

Developmental Cognitive Neuroscience
The developmental mismatch hypothesis (DMH) proposes that a mismatch in maturational timing of the amygdala and prefrontal cortex (PFC) drives adolescent sensation-seeking behaviour.

Exploring Age-Related Changes in Resting State Functional Connectivity of the Amygdala: From Young to Middle Adulthood

Frontiers in Aging Neuroscience, 2018
Functional connectivities of the amygdala support emotional and cognitive processing. Life-span development of resting-state functional connectivities (rsFC) of the amygdala may underlie age-related differences in emotion regulatory mechanisms.

Tau-PET pathology in the subregions of the amygdala and its associations with cognitive performance and neuropsychiatric symptoms in autosomal dominant Alzheimer’s disease

Alzheimer’s Research & Therapy
Background The amygdala plays a role in behavior and emotional response and is vulnerable to Alzheimer’s disease (AD) pathology, yet little is known about amygdala tau accumulation before clinical symptom onset.

When scientific paradigms lead to tunnel vision: lessons from the study of fear

npj Science of Learning, 2017
For the past 30 years, research on the amygdala has largely focused on the genesis of defensive behaviors as its main function. This focus originated from early lesion studies and was supported by extensive anatomical, physiological, and pharmacological ...

Beta-Adrenergic Receptor Blockade By Propranolol Enhances Retention In A Multitrial Passive-Avoidance Procedure [PDF]

, 2000
The effect of beta -adrenergic receptor blockade on retention in a mildly aversive passive-avoidance procedure was investigated. Rats were given passive-avoidance training-1 trial per day for 4 days-and were administered saline, the centrally and ...
