Alpha B.I. Coil Range

The Alpha B.I. coil range (coated) features a variety of sizes (40-70mm) to allow for simultaneous stimulation of two centres of the brain. This allows the user to investigate cortical interactions and the timing of information transmission.

The ergonomic design of the coil range provides comfort in positioning, allowing users to maintain the coil’s position for longer periods.
