Reduced amygdala volumes are related to motor and cognitive signs in Huntington's disease: The IMAGE-HD study

NeuroImage: Clinical, 2018
In Huntington's disease (HD), the presence of neurodegeneration in brain regions other than the striatum has been recently gaining attention. The amygdala is one such area, which has been investigated in only eight structural magnetic resonance imaging ...

GABA(B) receptor-mediated modulation of synaptic plasticity in the lateral amygdala [PDF]

, 2005
Fear conditioning, one of the most powerful and widely used methods to investigate the mechanisms of associative learning in animals, involves the pairing of an aversive stimulus such as a foot-shock (the unconditioned stimulus; US) with a neutral ...

The Key Role of the Amygdala in Stress [PDF]

, 2017
Several data highlighted that stress exposure is strongly associated with several psychiatric disorders. The amygdala, an area of the brain that contributes to emotional processing, has a pivotal role in psychiatric disorders and it has been demonstrated

Local synchronization of resting-state dynamics encodes Gray's trait Anxiety [PDF]

, 2013
The Behavioral Inhibition System (BIS) as defined within the Reinforcement Sensitivity Theory (RST) modulates reactions to stimuli indicating aversive events. Gray’s trait Anxiety determines the extent to which stimuli activate the BIS.

Vasopressinergic modulation of stress responses in the central amygdala of the Roman high-avoidance and low-avoidance rat [PDF]

, 1992
The central nucleus of the amygdala (CEA) is selectively involved in the passive component of the behavioral (immobility) and the accompanying parasympathetic response during conditioned, stressful environmental challenges. Vasopressinergic mechanisms in

Increased functional connectivity of amygdala subregions in patients with drug-naïve panic disorder and without comorbidities

Chinese Medical Journal, 2023
. Background:. Amygdala plays an important role in the neurobiological basis of panic disorder (PD), and the amygdala contains different subregions, which may play different roles in PD.

Modulating anxiety with extrasynaptic inhibition [PDF]

, 2014
Traumatic experiences and stress can lead to complex behavioral adaptations, including increased levels of anxiety and fear generalization. The neuronal mechanisms underlying such maladaptive behavioral changes are, however, poorly understood.

Depressive Symptoms and Amygdala Volume in Elderly with Cerebral Small Vessel Disease: The RUN DMC Study

Journal of Aging Research, 2011
Introduction. Late onset depressive symptoms (LODSs) frequently occur in elderly with cerebral small vessel disease (SVD). SVD cannot fully explain LODS; a contributing factor could be amygdala volume. We investigated the relation between amygdala volume

Amide Proton Transfer-Weighted MRI Might Help Distinguish Amnestic Mild Cognitive Impairment From a Normal Elderly Population

Frontiers in Neurology, 2021
Objectives: To evaluate whether 3D amide proton transfer weighted (APTw) imaging based on magnetization transfer analysis can be used as a novel imaging marker to distinguish amnestic mild cognitive impairment (aMCI) patients from the normal elderly ...
