Cognitive engagement induces area-specific fingerprints of dopamine, acetylcholine, serotonin, glutamate and GABA in prefrontal cortex and striatum

Sarah Shehreen, Seyed A. Hassani, Sofia Lendor, Adam R. Neumann, Kanchan Sinha Roy, Janusz B. Pawliszyn, Thilo Womelsdorf

The paper examines how cognitive engagement alters neurochemical profiles in the prefrontal cortex and striatum of nonhuman primates, identifying area-specific changes in dopamine, acetylcholine, serotonin, glutamate, and GABA.

Multi-Neuromodulator Measurements across Fronto-Striatal Network Areas of the Behaving Macaque using Solid-Phase Microextraction

Seyed A. Hassani, Sofia Lendor, Ezel Boyacı, Janusz B. Pawliszyn, Thilo Womelsdorf

The paper uses SPME to measure multiple neuromodulators in macaque brains during behavior, finding glutamate concentrations much higher than dopamine and acetylcholine.
