Nasal stimulation devices and methods

A system for stimulating nasal tissue of a subject, comprising:

• a handheld stimulator comprising:
• a stimulator probe comprising a first nasal insertion prong comprising a first electrode and a second nasal insertion prong comprising a second electrode, wherein the first and second electrodes are directed at least partially toward each other, such that the angle between the center of each electrode and an axis intersecting the first and second nasal insertion prongs is between 0 degrees and 90 degrees;
• and
• a stimulator body comprising a rechargeable power source and a control subsystem to allow the subject to control a stimulus to be delivered to the subject via the nasal insertion prong, wherein the control subsystem is configured to deliver a stimulus having a maximum amplitude between 10 μA and 100 mA.
