A method to provide secure attachment of miniature electric connectors in free-moving animals

A connection assembly for miniature electric plug and socket systems used in the recording and stimulation of the brain in free-moving animals was constructed from sew-on dress snaps. Two male portions of the snaps were cemented to the miniature electric socket or the dental acrylic mound that attached the socket to the skull. The female portions of the snaps were sewn to the ends of an elastic band. The wires that lead to the commutator passed through a hole in the elastic band. The plug and socket were securely attached to one another by snapping the elastic band to the skull.
