Amygdala volume is not associated with MRI-based markers of early cardiovascular disease [PDF]

Insights into Imaging
Background Recent PET studies suggest a link between amygdala activity and cardiovascular disease. Altered amygdala volumes are associated with increased stressor-evoked cardiovascular reactivity, which potentially increases the risk for cardiovascular ...

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.

A Review of the Metabolism and Relevance to Form and Formulation of Ketamine

European Psychiatry, 2023
Introduction Ketamine is a phenylcyclohexylamine derivative comprising a racemic mixture of S- and R-ketamine that possesses anesthetic, analgesic, anti-inflammatory, and antidepressant activity.

A 28-Day, Randomized, Controlled, Single-Blind, Phase 2 Study in Treatment-Resistant Major Depressive Disorder (TRD) Patients Receiving Intranasal Esketamine Comparing Addition of Almond Therapy TM with Treatment-as-Usual (TAU)

European Psychiatry, 2023
Introduction Treatment Resistant Depression (TRD) occurs in up to 30% of patients with Major Depressive Disorder (MDD). New treatments are clearly needed and there is a burgeoning interest in novel agents including ketamine.

Effective connectivity of the amygdala during the consumption of erotic, sexual humor, and monetary rewards with a DCM-PEB approach

PLoS ONE, 2022
While a large body of research exists on the processing of monetary rewards, less is known about sexual reward processing. This study aimed to identify effective connectivity for the consumption of sexual (erotic and sexual humor) and non-sexual ...

Vagus nerve stimulation (VNS) therapy in patients with treatment resistant depression: A systematic review and meta-analysis

Comprehensive Psychiatry, 2020
Background: Vagus nerve stimulation (VNS) therapy is approved for treatment-resistant depression (TRD). A recent 5-year comparative study prompted this review of its impact in this very severe population.

Decreased amygdala volume in adults after premature birth

Scientific Reports, 2021
Premature-born infants have impaired amygdala structure, presumably due to increased stress levels of premature birth mediated by the amygdala. However, accounting for lifelong plasticity of amygdala, it is unclear whether such structural changes persist

Connectivity-based parcellation of the amygdala and identification of its main white matter connections

Scientific Reports, 2023
The amygdala plays a role in emotion, learning, and memory and has been implicated in behavioral disorders. Better understanding of the amygdala circuitry is crucial to develop new therapies for these disorders.

Within amygdala: Basolateral parts are selectively impaired in premature-born adults

NeuroImage: Clinical, 2021
While it is known that whole amygdala volume is lastingly reduced after premature birth, it is unknown whether different amygdala nuclei are distinctively affected by prematurity.

Structural and functional abnormities of amygdala and prefrontal cortex in major depressive disorder with suicide attempts [PDF]

, 2019
Finding neural features of suicide attempts (SA) in major depressive disorder (MDD) may be helpful in preventing suicidal behavior. The ventral and medial prefrontal cortex (PFC), as well as the amygdala form a circuit implicated in emotion regulation ...
