Abstract
The invention relates to a method and apparatus for targeting electromagnetic stimulation on the human brain. According to the method, pulse-like electromagnetic fields are formed, which have a strong local electromagnetic maximum, the electromagnetic maximum of the field is targeted on the brain (2), the distribution, direction, and strength of the electromagnetic field arising in the brain are defined, and some physiological or biological response, such as, for example, a muscular response measured using electromyography, is measured. According to the invention, the position of the brain is defined in three-dimensional space and the position data is received in electrical form in a data-processing apparatus (8), the position data of the electromagnetic fields are received in the data-processing apparatus (8) in the same three-dimensional set of co-ordinates as the brain, the position data of the electromagnetic fields are combined with the position data of the brain (2), and a graphical presentation (9) of the position data of the electromagnetic fields and of the position data of the brain is formed with the aid of the data-processing apparatus (8).
