Abstract: A probe for recording and/or stimulating brain activity includes a connecting portion and at least one shank extending from the connecting portion. The at least one shank includes a first side, a second side opposed to the first side, and a fin protruding substantially perpendicularly from the second side and running on at least a part of a length of the at least one shank. The first side includes at least one recording and/or stimulating site.

Abstract: In a process for assembling a microstructure (1), provision is made of a first microstructure piece (2) having a receiving recess (3) in its surface and a second microstructure piece (5) having a connecting region (6) fitting into the receiving recess (3) and on which is arranged at least one electrical contact element (7a, 7b). Provision is made of a flexible cable (8) having a flat substrate layer (9) made of an electrically insulating material and at least one strip conductor (10) arranged thereon. The cable (8) has at least one tongue (14a, 14b) on which is arranged at least one counter-contact element (11a, 11b) connected to the strip conductor (10). The cable (8) and the microstructure pieces (5) are positioned relative to each other in a preassembly position in which the connecting region (6) is opposite the receiving recess (3) and the tongue (14a, 14b) is aligned between the connecting region (6) and the receiving recess (3).
