Is this only a neuroscience topic?

Given that core-matrix classifications exist I geology, I had thought the thalamus & basal ganglia core-matrix models were borrowed from that field. Does anyone know otherwise? LetThereBeNick (talk) 22:03, 25 September 2024 (UTC)[reply]

@LetThereBeNick I am not an expert on neuroscience. And I don't know anything about core-matrix classifications in geology. But I've been reading a 2024 review paper about the matrix-core subdivision of thalamic neurons recently.

In neuroscience, people talk about "matrix" as being for example all of the stuff which exists between cells, namely the extracellular matrix. Then inside this "matrix" or "network" of stuff, which is a hydrogel, there are neurons, axons and dendrites. So in that context, the matrix is everything except neurons, whereas in the thalamus context, the matrix is a subset of the neurons. Clearly this is contradictory usage.

In the thalamus context, the matrix neurons are a kind of general neurons which don't do so much information-wise. But the "core" neurons carry real sensory information to the cerebral cortex. They are more focused in location. So they bring more specific, detailed sensory data.

Does this all sound similar to the geology vocabulary? Where are the geology terms defined?
