The invention relates to a biophysiological regulator for therapeutic treatments, including brain stimulation coils (7) which generate current using a microcontroller (11). The invention includes a second microcontroller (16), a liquid crystal display (17), a selector (21) for selecting pre-recorded programs and a connection port (20) for an external device (19) which is provided with a speaker (24) and LEDs that indicate whether or not the battery is charged (18), the regulator is connected (27), an application is underway (26) and the battery is low (25), and an internal program (28) which regulates the frequency and typology of the output wave and the time. The invention also includes a tamper protection system formed by a microcontroller (29) inside a special connector (30) built into the assembly (applicator and cable), in which the internal software of the device reads the serial number located inside the microcontroller of the connector.
