Abstract: A method for determining position of an electrode lead inside a body tissue, including: 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 the received electrical signals; providing stored measurements or indications thereof; determining a position of the lead and/or the at least one macro electrode contact inside said body tissue based on the extracted SPK signals and the provided stored measurements or indications thereof.

Abstract: A method for selecting stimulation treatment parameter values, including: receiving signals related to a patient condition from at least one sensor, during and/or following at least one brain stimulation session, in which stimulation is delivered in at least one location within the brain, using at least one set of treatment parameter values; analyzing the received signals to quantitatively assess at least one treatment side effect and at least one symptomatic effect; selecting a set of treatment parameter values based on the quantitative assessment of the treatment side effects and the symptomatic effect.
