Abstract

The present publication discloses a device and method for generating magnetic pulses and directing them to brain. The device in accordance with the invention comprises means (15) for generating short, high energy current pulses (18), means (7) for controlling amplitude (16) of the current pulses (18), means (1) for generating high energy electromagnetic field stimulation pulses from the current pulses (18) and directing them to brain, and means (6, 14) for measuring biologic responses to the stimulation pulses. In accordance with the invention the device includes means (7) for creating such a pulse sequence (17) of electromagnetic pulses where the amplitude (18) varies irregularly.

Description

technical field [0001] The present invention relates to the non-invasive stimulation of the human brain according to predetermined pulses for the purpose of inferring information about the ability of the brain and its descending pathways to conduct neural signals. In particular, the invention relates to rapid pulse sequences combined with detected changes in biometrics to provide measurement information faster and more reliably than would otherwise be possible. In particular, the invention relates to what is mentioned in the preambles of the independent claims. Background technique [0002] Transcranial magnetic stimulation (TMS) provides a method of stimulating the motor areas of the human brain. Stimulation of the primary expressing areas of the muscles can result in the activation of corticospinal neural pathways originating in the cerebral cortex and creating pathways to the spinal cord, from where nerve signals are carried by peripheral nerves to the muscles and ultima...
