||"Randomly-connected networks of integrate-and-fire (IF) neurons are known to display asynchronous irregular (AI) activity states, which resemble the discharge activity recorded in the cerebral cortex of awake animals.
Here, we investigate the occurrence of AI states in networks of nonlinear IF neurons, such as the adaptive exponential IF (Brette-Gerstner-Izhikevich) model. This model can display intrinsic properties such as low-threshold spike (LTS), regular spiking (RS) or fast-spiking (FS). We successively investigate the oscillatory and AI dynamics of thalamic, cortical and thalamocortical networks using such models.
||This package provides a series of codes that simulate networks of spiking neurons (excitatory and inhibitory, integrate-and-fire or Hodgkin-Huxley type, current-based or conductance-based synapses; some of them are event-based). The same networks are implemented in different simulators (NEURON, GENESIS, NEST, NCS, CSIM, XPP, SPLIT, MVAspike; there is also a couple of implementations in SciLab and C++).
The codes included in this package are benchmark simulations; see
the associated review paper (Brette et al. 2007). The
main goal is to provide a series of benchmark simulations of
networks of spiking neurons, and demonstrate how these are implemented in the
different simulators overviewed in the paper. See also details in the
enclosed file Appendix2.pdf, which describes these different
benchmarks. Some of these benchmarks were based on the
Vogels-Abbott model (Vogels TP and Abbott LF 2005).
