Dear colleagues,
I’m not sure about the meaning of “thick long-range axonal tracks” in the passage below: in particular, I can’t understand how “thick” relates to “axonal tracks”.
Thank you so much for any hint!
************
What is the “social brain” and what is it for? The fully developed adult human brain is organized as anatomically connected and functionally coupled intrinsic networks. These networks are held together by *** thick, long-range axonal tracks *** [Bullmore and Sporns (2012)]. Of specific importance to both allostasis and social processing are the salience network [ and the default mode network (also called the mentalizing network. The salience and default mode networks together make up an integrated network for implementing allostasis and represent its sensory consequences, called interoception [Kleckner et al. (2017)]

tracts
Likewise, axonal tracts are groups of axons running together on such a scale that they can be seen by the naked eye.

I hope that makes "thick, long-range" self explanatory.

Note from asker:
Thank you very much, Phil! So you think it may be a type: tracts instead of "tracks"? Because I've found some instances of "axonal tracks" https://www.google.com/search?q=%22axonal+tracks%22&ei=14iBYJyhN9X6sAeTlpvACA&oq=%22axonal+tracks%22&gs_lcp=Cgdnd3Mtd2l6EAMyBggAEAgQHjoJCAAQsAMQCBAeUNElWNElYNosaAFwAHgAgAGBA4gBlwSSAQcwLjEuMC4xmAEAoAEBqgEHZ3dzLXdpesgBAcABAQ&sclient=gws-wiz&ved=0ahUKEwjc6MHSiJLwAhVVPewKHRPLBogQ4dUDCA8&uact=5 and I thought it might mean something like "paths" or "trajectories"... |

Thanks. Yes, it gets hardly any hits compared to "tracts".

Multiple
sclerosis is a disorder that causes sporadic autoimmune
attacks and demyelination of axonal tracts in the brain.
The probability that a specific tract will be affected by
a focal lesion is proportional to its volume, rendering
longer tracts more vulnerable. Accordingly, greater
degrees of lesion load are associated with greater loss of
topological efficiency owing to greater damage to longdistance axonal projections128
