Transcranial electrostimulation apparatus and method
First Claim
Patent Images
1. A method for effecting transcranial electrostimulation including the steps of:
- producing an asymmetrical tone burst envelope comprising a predetermined number of squarewave pulses, a first portion of which constitutes a high amplitude burst followed by a second portion which constitutes a low amplitude burst;
repeating the asymmetrical tone burst successively at a repetition frequency that is between 70 Hertz and 85 Hertz; and
delivering the repeated tone burst signals to electrodes of a transcranial electrostimulation apparatus.

Abstract
Transcranial electrostimulation apparatus and method includes a first generator of bipolar pulses of a first predetermined frequency. A source of modulating control signals, producing an output at a second frequency less than the first predetermined frequency, is used to cause the output pulses from the first generator of pulses to vary in amplitude in a predetermined asymmetrical pattern at the frequency of the modulating control signals, with the asymmetrical pattern of signals applied to output electrodes designed to be attached to the scalp of a patient.

8. A transcranial electrostimulation apparatus including in combination:
-
a source of bipolar pulses of a first predetermined frequency;
source of modulating control signals to yield a second frequency which is less than said first predetermined frequency;
an amplitude control means responsive to the modulating control signals and coupled to the source of bipolar pulses at the first predetermined frequency for causing the amplitude of bipolar pulses in successive groups of bipolar pulses to vary in accordance with a predetermined asymmetrical pattern at the second frequency. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
