A brain-computer interface is disclosed. The brain-computer interface includes a spatially-adjustable animalia-engaging portion connected to a computing resource interface portion. The computing resource interface portion includes an actuator that is connected to at least one spatial-adjuster-component of the spatially-adjustable animalia-engaging portion. The actuator is configured to rotate the at least one spatial-adjuster-component for extending a distal portion of a length of a micro-electrode of at least one subassembly of the spatially-adjustable animalia-engaging portion beyond a distal end of a micro-electrode guide portion of the spatially-adjustable animalia-engaging portion.
