An intracortical-detection device including: at least one electrode that contacts a group of neurons； a first body, forming a surface that contacts a portion of a cerebral region； a first motor that moves the electrode with respect to the first body； a second motor； and a second body, operatively connected to the second motor, the first and second bodies being able to slide with respect to one another in a first direction, under the action of the second motor. The detection device moreover includes a sensor generating an electrical signal indicating a pressure exerted by the portion of cerebral region on the surface.
