Is it true that neurotransmitter distribution and usage vary significantly across the brain?
Yes. Extensive neuroimaging and mapping studies confirm that neurotransmitter receptor densities, usage, and distributions vary significantly across different regions of the human brain.
Verdict: SUPPORTED · 7 sources for, 0 against · Last checked
The analysis
The retrieved papers consistently demonstrate, through PET imaging, gene expression, and spatial correlation analyses, that neurotransmitter receptors and systems exhibit marked regional variations and topographies across the brain. There are no papers refuting this well-established neuroscientific fact.
Evidence for · 7
The study maps densities for 27 neurotransmitter receptors and transporters, demonstrating considerable regional variation across the human brain.
