Difference between local connectivity , short-range connectivity and long-range connectivity

[JIAQI ZHANG]

hi! I have a question about the definition of connectivity.

Are these explanation right or wrong?

1、local connectivity: connectivity between vertex on triangles of surface

2、short-range connectivity: connectivity between neural mass, i.e. E-E, I-I, E-I, I-E

3、long-range connectivity: connectivity between regions of brain, i.e. white fibers

I know it may be a easy and basic question but I'm really puzzled! Sorry to be a bothor!

Hi,

As mentioned in my previous email, I suggest you to read the paper of Sanz-Leon et al. 2015, where you can find all the necessary definitions and information for large-scale brain network modeling using TVB!

In TVB, you can find two types of connectivity to build a brain avatar:

1. global or long-range connectivity: connection between brain regions
2. local or short-range connectivity: connection between vertices

The connection between two neural masses of a neural mass model is called intrinsic or internal connection.
