Harmonic interface
The harmonic interface was a device that allowed Commander Paul Stamets to link his neurons to the mycelial network, so as to operate the spore drive on .

In 2257, Stamets modified the interface in an effort to link a multidimensional fungal parasite to Ensign Sylvia Tilly's central nervous system, allowing it to speak through Tilly's mouth. However, the link required a cortical implant to function. ()
