Modelling and Analysis of Electrical Potentials Recorded in Microelectrode Arrays (MEAs)
TLDR
We use a biophysical forward-modelling formalism based on the finite element method (FEM) to establish quantitatively accurate links between neural activity in the slice and potentials recorded in the MEA set-up. Expand
