abstract = {Background: The structure of the brain plays a crucial role
in shaping its activity. However, the link between
structural connectivity and observed neuronal activity
remains incompletely understood. Previous research utilizing
a large-scale spiking network model of leaky
integrate-and-fire neurons has addressed this question for
macaque cortex [1,2]. Here, a similar framework is employed
to investigate human cortex in a model that links the
cortical network structure to the resting-state activity of
neurons, populations, layers, and areas.Objectives: The
objective of this study is to investigate the link between
structural connectivity and observed neuronal activity in
human cortex using a large-scale spiking network model, and
to create a platform for multi-scale in silico studies of
human cortex.Materials and Methods: The model includes all
34 areas in a single hemisphere of human cortex according to
the Desikan-Killiany parcellation. Our approach integrates
cortical data on architecture, morphology, and connectivity
into a multi-scale framework for predicting neuron
connections. Each cortical area is represented by a 1 $mm^2$
layered microcircuit adapted from [3] with the full density
of neurons and synapses. Inter-area connectivity relies on
diffusion tensor imaging data [4] and the determination of
laminar patterns of synaptic connectivity takes into account
human neuron morphology data [5]. The model comprises 4
million neurons and 50 billion synapses, simulated with the
NEST simulator on the supercomputer JURECA-DC. Results and
Conclusions: Simulations of the model with uniform synaptic
weights reveal a state with asynchronous and irregular
activity that deviates from experimental recordings in terms
of spiking activity and inter-area functional connectivity.
Increasing inter-area synapse strength enables the model to
capture both microscopic and macroscopic resting-state
activity of human cortex measured via electrophysiological
recordings and fMRI [6]. Furthermore, the model reveals
rapid propagation of the effects of a single-spike
perturbation across the entire network. This suggests
individual spikes play a role in fast sensory processing and
behavioral responses in the cortical network. Overall, the
model serves as a basis for the investigation of multi-scale
structure-dynamics relationships in human cortex.},
