Significats de amygdala reactivity en anglès

Increased amygdala reactivity has been discussed in the context of major depression.

Results: Before therapy, both patient groups equally showed elevated amygdala reactivity to sad faces compared with HC.

The aim of this study was to assess amygdala reactivity in BPD patients relative to normal control subjects.

Objective: In a previous study, we demonstrated that amygdala reactivity to masked negative facial emotions predicts negative judgmental bias in healthy subjects.

The main results were positive associations of separation anxiety scores with amygdala reactivity to emotional faces as well as increased amygdala grey matter volumes.

Our data suggest a potential molecular mechanism by which a reduced capacity for negative feedback regulation of 5-HT release is associated with increased amygdala reactivity.

We observed a significant inverse relationship wherein greater mPFC 5-HT(2A) density was associated with reduced threat-related right amygdala reactivity.

In the present study automatic amygdala reactivity to facial emotion was investigated as a function of alexithymia (as assessed by the 20-Item Toronto Alexithymia Scale).

We found a significant inverse relationship wherein 5-HT1A autoreceptor density predicted a notable 30-44% of the variability in amygdala reactivity.
