Design of the face profession association task. Inside the magnetic resonance scanner, persons performed the face‐profession association task that was interleaved with a visuo‐motor task. During the visuo‐motor task, they were required to judge whether the ears of a shadow‐masked face contour were closer to the left or the right shoulder. In the face profession association task participants had to memorize the face‐profession associations and to judge whether the face fitted well with the underlined profession or not. Thereafter, they performed a recall test outside the scanner. The participants were provided with a printed list of all the professions and faces seen in the scanner. They had to write down the associated professions below the faces. The figure is adapted with permission from Thielen, J.

The increase in medial prefrontal glutamate/glutamine concentration during memory encoding is associated with better memory performance and stronger functional connectivity in the human medial prefrontal‐thalamus‐hippocampus network.
