Abstract: The invention concerns a method for connecting first contact studs of a structure bearing electrodes for measuring or for stimulating a physiological activity with second studs of at least a downstream circuit, each second stud being traversed by an opening perforating the downstream circuit. The method includes the following steps: a) placing the downstream circuit on the structure, so that the opening of a second stud is located opposite a first stud; and b) depositing in the opening of the second stud a conductive material providing the connection between the first second stud opposite.
