Estimation of initiated local field potential by neurons in heterogeneous tissue environment using admittance method

In order to decode the relationship between the activity of neuronal networks in the brain and the physiological response, multiple recording methods are available to monitor the spatial-temporal response of the neurons. Compared to single neuron recording that is useful for finding neuronal response, local field potential (LFP) recording allows for analysis of a larger neuronal network response. LFP is a combinational effect of the asynchronous action potentials from multiple neurons and can be recorded using implanted microelectrodes. Accurately calculating the LFP of a simulated neuronal network allows for optimal electrode placement for electrical stimulation and recording. The simulated LFP on a proximal recording electrode due to the neuronal firings of a multineuron network can be compared with the recorded LFP from a relevant experiment. In this work we compare two different methods for solving multineuron network field potentials.
