Abstract: An electrical connector assembly comprising an electrode interface board with a socket portion of a subminiature dual-row electrical connector attached to the top surface of a first printed circuit board and a first plurality of magnets attached to the bottom surface. The socket portion comprises a plastic housing and a plurality of female contacts with protruding contact points. The connector assembly further comprises a head stage with a top socket, connector and a second printed circuit board. A plug portion of the electrical connector is attached to the bottom surface of the second printed circuit board and a second plurality of magnets is attached to the bottom surface. The plug portion comprises a plastic housing and a plurality of male contacts with detents. The male contacts mate with the female contacts so that the protruding contact point of each female contact touches an inside distal surface of a male contact.

Abstract: An apparatus for use in neurophysiological research and clinical diagnosis comprises a hollow body having a plurality of electrode wires slidably carried therein. Each electrode wire is carried on a shuttle that is slidably mounted in a slot in an interior wall of the hollow body.

Abstract: A mobile neurological data acquisition system. A multiplexing circuit is utilized to combined multiple electrical-neurological signal inputs (synaptic “spikes”, EEG, EKG, EMG). A programmable logic device is utilized to package the combined signal into a packet containing a header and a footer. An analog transmitter is utilized to modulate a RF signal with the packetized combined signal and broadcast it to an analog receiver, where it is demodulated. An analog-to-digital converter is used to convert the demodulated combined analog signal into a combined digital signal. A computer and software algorithms are used to demultiplex the combined digital signal into discrete digital representations of the original electrical-neurological signals. The discrete digital signals are sent to a printer or video display for human analysis or stored on digital media such as a hard disk, a floppy disk, a magnetic tape, or a CD-ROM.
