Abnormal amygdala subregional-sensorimotor connectivity correlates with positive symptom in schizophrenia

NeuroImage: Clinical, 2020
Altered resting-state functional connectivity (rsFC) of the amygdala has been demonstrated to be implicated in schizophrenia neuronal pathophysiology.

Stress-induced cortisol response is associated with right amygdala volume in early childhood

Neurobiology of Stress, 2021
Rodent research suggests that dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and the resulting cortisol stress response can alter the structure of the hippocampus and amygdala.

Fear conditioning- and extinction-induced neuronal plasticity in the mouse amygdala [PDF]

, 2009
Experience-dependent changes in behavior are mediated by long-term functional modifications in brain circuits. To study the underlying mechanisms, our lab is using classical auditory fear conditioning, a simple and robust form of associative learning. In

Central amygdala micro-circuits mediate fear extinction [PDF]

, 2021
The central amygdala inhibitory microcircuits mediate fear extinction by reversible, stimulus- and context-specific changes in neuronal responses. These alterations are absent when extinction is deficient and selective silencing of PKCδ neurons impairs ...

The Corticomedial Amygdala and Learning in an Agonistic Situation in the Rat [PDF]

, 1984
Social agonistic behaviour of intact male rats is strongly reduced by the experience of defeat by a dominant male conspecific. Small electrolytic lesions in the corticomedial amygdala strongly affected this behavioural change due to defeat. No effects of

Peripherally-administered amphetamine induces plasticity in medial prefrontal cortex and nucleus accumbens in rats with amygdala lesions: implications for neural models of memory modulation

Frontiers in Behavioral Neuroscience, 2023
The amygdala has been implicated in a variety of functions linked to emotions. One popular view is that the amygdala modulates consolidation in other brain systems thought to be mainly involved in learning and memory processes. This series of experiments

Dreaming in Urbach-Wiethe patients the effect of amygdala damage on dreaming [PDF]

, 2012
Includes bibliographical references.As it stands, there is a paucity of literature looking at the effect of damaged amygdalae on dreaming and dream content.

Asymmetric engagement of amygdala and its gamma connectivity in early emotional face processing.

PLoS ONE, 2015
The amygdala has been regarded as a key substrate for emotion processing. However, the engagement of the left and right amygdala during the early perceptual processing of different emotional faces remains unclear. We investigated the temporal profiles of

Serotonin transporter in the temporal lobe, hippocampus and amygdala in SUDEP [PDF]

, 2022
Several lines of evidence link deficient serotonin function and SUDEP. Chronic treatment with serotonin reuptake inhibitors (SRIs) reduces ictal central apnoea, a risk factor for SUDEP.
