The paper investigates how the brain prioritizes cue-based versus episodic fear memories over time and finds that anxiety alters this process.

This study shows that fear conditioning in humans leads to distinct movement patterns, and training active defensive movements reduces fear responses long-term.

The paper investigates reciprocal inhibition between the amygdala and vmPFC in PTSD patients, linking attentional biases to symptom clusters and amygdala reactivity.

This study uses neural reinforcement to alter resting-state functional connectivity in the threat regulation network, showing increased prefrontal connectivity with amygdala and ventral temporal cortex, but no Hebbian-like learning.

The paper investigates how spatial frequency affects metacognitive performance in schizophrenia patients and controls, finding atypical SF dependence in patients.

The paper uses 7T fMRI to show pulvinar input to V1 superficial layers mediates threat anticipation, not just threat perception.
