1. A device for applying transcutaneous electrical stimulation to a patient, comprising:
an elongate support configured to be coupled to a forehead of the patient, the elongate support comprising a support surface comprising a first lateral zone, a second lateral zone, and a central zone therebetween, wherein the first lateral zone has a first lateral end opposite the central zone, and the second lateral zone has a second lateral end opposite the central zone;
a first electrode coupled to the first lateral zone and a second electrode coupled to the second lateral zone, the first electrode and the second electrode configured to stimulate a trigeminal nerve of the patient;
a conductive gel applied to between about 50% and about 80% of the support surface, wherein the first lateral end, the second lateral end, and the central zone are devoid of the conductive gel; and
a signal generator configured to supply pulses to the first electrode and the second electrode,
wherein the support is configured to removably couple to the signal generator and the support comprises at least two magnetizable metal connectors on a surface of the support facing away from the conductive gel, the at least two magnetizable metal connectors configured to removably couple to at least one magnet coupled to the signal generator.
