Abstract
The present invention relates to a stimulator head of a magnetic stimulator used in the stimulation of living tissue such as the human brain. Such a stimulator bead comprises a stimulator head body (3) suited for mounting the stimulator head on the magnetic stimulator equipment, at least one coil (1) which is connected to said stimulator head body (3) and is designed suitable for generating a stimulating magnetic field, and conductors (7) for passing electric current from said magnetic stimulator into any of said at least one coil (1). According to the invention, the stimulator head includes a housing (2) which is connected to said stimulator head body (3) and is designed to enclose at least one air-tight space (5) which further separates each of said at least one stimulator coil (1) from the other parts of said housing (2) facing the object being stimulated. Further according to the invention, each of said at least one coil (1) is placed in said housing (2), whereby an acoustic insulation can be attained between each of said at least one coil (1) and the object being stimulated by virtue of bringing the pressure in said air-tight space (5) to a substantially low level.
