Overview
The purpose of this study is to investigate the neural mechanisms by which acute stress influences statistical learning and episodic encoding.
Description
This study aims to assess the neural and behavioral mechanisms by which acute stress modulates episodic encoding (which involves the trisynaptic pathway: entorhinal cortex, dentate gyrus, cornu ammonis [CA] 3, and CA 1) and statistical learning (monosynaptic pathway: entorhinal cortex, CA1) in humans.
