A newly designed intrafascicular electrode for chronic neural recording was studied by implanting 12 electrodes in the radial nerves of 6 cats for 6 months. Action potentials were monitored at specified intervals throughout the experiment. The number and size of the signals recorded suggest that this type of electrode provides information that is(More)
OBJECTIVE Most phosphorus-31 magnetic resonance spectroscopy ((31)P-MRS) studies have described measures of lower membrane anabolism or greater catabolism in the frontal lobes of patients with schizophrenia. The purpose of the present study was to evaluate whether these findings can also be detected in young subjects at genetic risk for schizophrenia. (More)
We are developing a new type of bipolar recording electrode intended for implantation within individual fascicles of mammalian peripheral nerves. In the experiments reported here we used electrodes fabricated from 25 microns diameter Pt wire, 50 microns 90% Pt-10% Ir wire and 7 microns carbon fibers. The electrodes were implanted in the sciatic nerves of(More)
The effects of small dc bias currents on the offset potentials of disposable ECG electrodes (four brands of Ag-AgCl and two brands of stainless steel) were examined. After periods ranging from a few minutes to several days, samples of all electrode types exhibited offset potentials exceeding 200 mV after subjection to dc bias currents over 200 nA. All(More)
A graph-theoretical approach is proposed to facilitate pattern matching in post-tonal music analysis with pitch-class set theory, in which music perception is taken into account by incorporating stream segregation—a model of the perceptual organization of music. A piece of music is modelled as a graph, with each musical note presented as a vertex and the(More)
The public opinion pays much attention to the Nobel Prize as an indicator for the scientific efficiency of a university or a country in connection with foundation of so-called elite universities. The former holder of the psychiatric chair in Jena and discoverer of the electroencephalogram Hans Berger (1873 - 1941) came into discussion as candidate for the(More)
Utilizing an automated test system, measurements of the 10-Hz impedance were made with electrode pairs joined gel-to-gel and electrode quartets on the skin of the backs of human volunteers. Two skin preparation procedures were examined. As a minimum skin preparation, the electrodes were applied to clean, dry skin from which body hair had been shaved if(More)
