Embodiments discussed herein facilitate identification of a target area within a region of a brain for stimulation via one or more BS (Brain Stimulation) electrodes. One example embodiment comprises generating, based on radiological imaging of a region of a brain of a patient and BS electrode lead(s), a patient-specific anatomical model of the region and lead(s); populating the patient-specific anatomical model with neuron models based on associated neuronal densities of at least one of the region or one or more sub-regions of the region; constructing a patient-specific local field potential (LFP) model of the region based on the patient-specific anatomical model and location(s)/orientation(s) of the one or more BS electrode leads; and identifying, via the patient-specific LFP model of the region, a target area within the region for at least one of monitoring or treatment of a medical condition via the one or more BS electrode leads.
