Modeling local field potentials (Bedard et al. 2004)
|
|
|
|
|
|
|
This demo simulates a model of local field potentials (LFP) with
variable resistivity. This model reproduces the low-pass
frequency filtering properties of extracellular potentials. The
model considers inhomogeneous spatial profiles of conductivity
and permittivity, which result from the multiple media (fluids,
membranes, vessels, ...) composing the extracellular space around
neurons. Including non-constant profiles of conductivity enables
the model to display frequency filtering properties, ie slow
events such as EPSPs/IPSPs are less attenuated than fast events
such as action potentials. The demo simulates Fig 6 of the
paper.
