#46: On the relationship between structure and function in cortical networks – with Michael Reimann

Detailed reconstructed neuronal morphologies are now widely available, but how do you wire them up in a network?

The shape of the neurons provides a key constraint: synapses only can occur when presynaptic axon terminals are physically close to postsynaptic dendrites.

Today’s guest has used this and other principles to construct large-scale cortical model networks and to study the relationship between the anatomical connectivity and function of such networks.
