Hello!
I am new exploring the Allen Brain Map resources, so maybe this is a silly question. Exploring the Spatial Transcriptomics database for mouse brain, I noticed that when filtering by neurotransmitter type and NA , the results include over 1.5 million cells distributed across the entire brain. This is puzzling, as noradrenergic cells are known to be restricted to specific nuclei in the brainstem.
Can anyone clarify what the neurotransmitter type filter represents in this context? It seems unlikely to correspond directly to the neurotransmitter released by the cells. Thank you in advance!
