Tumors in portions of a subject's body that have a longitudinal axis (e.g., the torso, head, and arm) can be treated with TTFields by affixing first and second sets of electrodes at respective positions that are longitudinally prior to and subsequent to a target region. An AC voltage with a frequency of 100-500 kHz is applied between these sets of electrodes. This imposes an AC electric field with field lines that run through the target region longitudinally. The field strength is at least 1 V/cm in at least a portion of the target region. In some embodiments, this approach is combined with the application of AC electric fields through the target region in a lateral direction (e.g., front to back and/or side to side) in order to apply AC electric fields with different orientations to the target region.

Devices, systems and methods are disclosed for treating or preventing an autism spectrum disorder, a pervasive developmental disorder, or a disorder of psychological development. The methods comprise transmitting impulses of energy non-invasively to selected nerve fibers, particularly those in a vagus nerve. The nerve stimulation may be used as a behavior conditioning tool, by producing euphoria in an autistic individual. Vagus nerve stimulation is also used to modulate circulating serotonin levels in a pregnant woman so as to reduce the risk of having an autistic child; modulate the levels of growth factors within a child; promote balance of neuronal excitation/inhibition; modulate the activity of abnormal resting state neuronal networks; increase respiratory sinus arrhythmia; and avert episodes of motor stereotypies with the aid of forecasting methods.

The present invention relates to methods of increasing metabolic activity and stimulating cell proliferation of biological cells through the use of pulsed electric field (PEF) treatment, especially through the use of nanosecond pulsed electric field (nsPEF) treatment.

This application discloses configurations for arranging transducer arrays on a person's head to impose tumor treating fields (TTFields) in the brain at field strengths that are as uniform as possible throughout the entire brain. In some embodiments, L-shaped sets of electrodes are positioned near the right and left ears, each with a horizontal arm above the ear and a vertical arm behind the ear. Optionally, these embodiments may be combined with a second pair of electrodes positioned on top of the head and behind the neck. In other embodiments, one pair of electrodes is positioned above the right ear and on the left/rear portion of the neck; and a second pair of electrodes is positioned above the left ear and on the right/rear portion of the neck. These configurations improve the uniformity of the electric fields imposed throughout the brain, and are particularly useful for preventing and/or treating metastases.
