1. A method for determining position of an electrode lead inside a body tissue, comprising:
receiving electrical signals recorded from at least one macro electrode contact of an electrode lead positioned inside a body tissue;
extracting spiking (SPK) signals from said received electrical signals, wherein said extracting comprises filtering said received electrical signals to obtain said SPK signals within a frequency range of 250 Hz-7000 Hz;
providing stored measurements or indications thereof;
determining a position of said lead and/or said at least one macro electrode contact inside said body tissue based on said extracted SPK signals and said provided stored measurements or indications thereof.
