Post-traumatic stress disorder (PTSD) persists when stress biases memory systems-broadening threat engrams, weakening context-appropriate inhibition, and rendering extinction fragile. Integrating preclinical and human evidence, we argue that these liabilities are tractable within a circuit-informed framework that aligns behavioral procedures with the biology of fear memory. Extinction can be...
Physiological, pharmacological, and pathological alterations of consciousness provide critical windows into its neural substrates. Given the inherent complexity and multidimensionality of consciousness, defining quantitative, dynamic signatures of neural activity, and translating them into clinically applicable tools remains challenge. This study aimed to build an electroencephalography...
