Multi-side TMS describes the use of multiple independently controlled stimulation coils which all are stimulating one subject. It is used for the investigation of functional connectivity within complex interconnected networks. By varying the timing and location of each coil, the temporal and spatial relationships between brain regions can be investigated. The operator can e.g. stimulate multiple locations with or without time delay between the stimulation pulses. It is for instance possible to suppress one hemisphere while activating the other stimulation side.
Another approach is to combine a “virtual lesion” which is evoked by applying rTMS on one or more brain area(s) and using single-pulse stimulation onanother area. Up to 4 selected brain regions can be stimulated with different patterns and intensities at the same time while using highly focal coils.
Major considerations and solutions:
Safe and flexible operation of up to 4 stimulators
Patented safety concept with safety restrictions on stimulation intensities and frequencies.
Set and control the stimulation parameters freely through different options (USB, analogue & digital interface, triggers in/out, front panel).
Coil sizes and abilities
Variety of stimulation coils – different sizes and housings.
Application-oriented coil geometries for specific applications.
Precision of stimulation coils
Extraordinary temporal and spatial resolution through continuous
Reproducible results with different protocols
Stable output power through all stimulation patterns (single-pulse,
rTMS, Trains, Theta-burst, QPS).
Stimulation of two spatially close brain areas at the same time
Decentral mini-coils enable the stimulation of areas that are only 2-3cm apart.
