Emotion circuits research, explained
8 open-access emotion circuits studies, each with a flashcard deck and a quiz.
- How different types of meditation shape everyday brain responses
Meditation training can change how your brain reacts to emotional images even when you are not actively meditating.
- How does the brain recognize emotions in music?
Damage to a distributed brain network, particularly in areas like the insula and amygdala, impairs a person's ability to identify emotions expressed in classical and film music.
- Does emotional speech synchronize brains across listeners?
When people listen to the same emotional stories, their brain activity and functional connections synchronize, especially during highly intense or negative moments.
- Why do we remember upsetting things but forget their context?
Negative images were remembered better on their own but linked less well to other images, and brain scans showed the amygdala tracking the first effect and a dampened hippocampus the second.
- Is amygdala activity to emotional faces stable enough to be a biomarker?
Although emotional faces reliably activated the amygdala and deactivated the subgenual cingulate on average, how strongly each individual responded was mostly not consistent from one scan to the next.
- Do fear circuits respond differently in women with PTSD?
Women with PTSD showed more amygdala and insula activity than controls during an emotional distraction task, and their insula responded especially when they paid attention to fearful faces.
- Is there a fast shortcut from the eyes to the amygdala for faces?
Early brain responses to faces were best explained by a model that includes a direct subcortical route to the amygdala, regardless of the face's emotion.
- Where does nociplastic pain hitch a ride in the amygdala?
In TRAP2 mice, inflammation-tagged parabrachial (elPB) neurons project most densely to posterior capsular central amygdala (pCeC) and form strong synapses with pain-tagged pCeC cells; exciting those CeA neurons recreates bilateral hindpaw sensitization.
