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 ...

Dissociation of affective modulation of recollective and perceptual experience following amygdala damage [PDF]

, 2003
It has been suggested that similar neural mechanisms may underlie the affective modulation of both recollective and perceptual experience. A case is reported of a patient who has bilateral amygdala damage and marked impairment in the perception of ...

Presynaptic mechanisms determining the dynamic range of neurotransmitter release in the lateral amygdala [PDF]

, 2008
The amygdala is a central brain structure receiving sensory information from diverse regions of the central nervous system. Cortical and thalamic axons converge to the lateral amygdala (LA) which is thought to be the main site for fear-induced ...

Abnormal anatomical connectivity between the amygdala and orbitofrontal cortex in conduct disorder [PDF]

, 2012
Objective: previous research suggested that structural and functional abnormalities within the amygdala and orbitofrontal cortex contribute to the pathophysiology of Conduct Disorder (CD).

Amygdala Plasticity and Pain

Pain Research and Management, 2017
The amygdala is a limbic brain region that plays a key role in emotional processing, neuropsychiatric disorders, and the emotional-affective dimension of pain.

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 ...

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.

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.

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 ...
