Simulating Cortical Electrical Signals Using the Mouse V1 Model

The mouse V1 model was used to simulate electrical signals (LFP/CSD). Feedback from a higher cortical area was added to obtain a better match with LFP recorded in vivo.

Modeling the mammalian cortex: Layer IV of mouse V1

Biologically realistic models of the cortical lamina (Layer IV; L4) of mouse primary visual cortex (V1) were constructed at the biophysically detailed and point-neuron levels, to explore mechanisms underlying cortical computations in extensive simulations with a battery of visual stimuli. Learn more about the Layer 4 model.

DiPDE

The displacement integro-partial differential equation (DiPDE) population density model refers to a simulation platform for numerically solving the time evolution of coupled networks of neuronal populations. Instead of solving the subthreshold dynamics of individual model leaky-integrate-and-fire (LIF) neurons, DiPDE models the voltage distribution of a population of neurons with a single population density equation. In this way, DiPDE can facilitate the fast exploration of mesoscale (population-level) network topologies, where large populations of neurons are treated as homogeneous with random fine-scale connectivity.
