Abstract: The invention relates to a contact for a direct plug-in connector having two strips made of sheet-metal material that are arranged next to one another in an insertion portion and in a contact portion, wherein the insertion portion is provided for insertion into a through-opening, which is electrically conductive at its inner wall, in a printed circuit board and the contact portion is provided to make electrical contact with the inner wall of the through-opening, wherein the two strips are connected together in a connection portion that is provided for connecting to a cable strand, and wherein a connecting portion is located between the connection portion and the contact portion, wherein the two strips are located in a common plane and formed in an L-shaped manner in the connecting portion, wherein the legs of the connecting portion that proceed from the connection portion extend parallel to one another and the legs of the connecting portion that are connected to the contact portion extend towards one another.

Abstract: A fitting element includes a first fitting section for connection with a spacer element, and a second arresting section for arresting with a circuit board. A central section is arranged between the fitting section and the arresting section and serves for forming a first stop for the spacer element, and a second stop for the circuit board. The fitting element is connected with an associated spacer element for forming a fitting device. The spacer element is fitted to a first circuit board. A second circuit board is then arrested with the fitting element. In this way two circuit boards can be connected with each other in a simple, flexible and automated way.

Abstract: The invention relates to a direct plug-in connector for making electrical contact with printed circuit boards, comprising a housing and at least one contact, which is connected to the housing, for insertion into a first passage opening of a printed circuit board, which first passage opening is electrically conductive on the inner wall, wherein at least one latching device for securing the housing on the printed circuit board is provided, wherein the latching device has at least one elastically resilient latching arm which is integrally connected to the housing and has a latching projection in the region of its free end, wherein the latching arm and the housing are separated by means of an intermediate space which runs perpendicularly to a supporting face of the direct plug-in connector on the printed circuit board and in a straight line.

Abstract: Methods and composition for inducing, detecting and modulating seizure in animal systems are provided. Methods for inducing seizure comprise (1) electrically stimulating an unanesthetized fly and detecting seizure induction in the fly (2) electrically stimulating a fly with less than 10V and detecting seizure induction in the fly; (3) electrically stimulating a population of wild-type flies and detecting seizure induction in most of the flies and (4) electrically stimulating a population of flies and quantitatively detecting seizure induction in the flies across genotypes or experience. Methods for modulating seizure induction comprise changing the activity of a novel seizure regulator in an animal system and confirming a resultant change in seizure inducibility of the system.
