Disclosed are methods and systems for non-invasive ultrasound neuromodulation of superficial cortex of the brain or stimulation of nerve roots or peripheral nerves. Such stimulation is used for such purposes as determination of motor threshold, demonstrating whether connectivity to peripheral nerves or motor neurons exists and performing nerve conduction-speed studies. Neuromodulation of the brain allows treatment of conditions such as depression via stimulating superficial neural structures that have connections to deeper involved centers. Imaging is optional.
