The isolated retina of rabbit lies on nylon tissue fixed in a ring, which is placed in a chamber. The lower side of the retina, by choice the receptor or ganglion cell side, is superfused by a plasma saline mixture kept at 35 degrees C. At the upper side of the retina, warm humidified oxygen is added. The two sides are isolated from each other by a rubber(More)
Over the last few years our group has been strongly involved in the study of the chemistry of oligosilanes. 1,2 In particular, the development of a convenient synthetic access to structurally diverse oligosilanyl anions 3À6 allowed the preparation of a huge variety of previously unknown small polysilanes. Some 40 years ago Ishikawa and Kumada discovered the(More)
b S Supporting Information ' INTRODUCTION In recent years small alkylated polysilanes 1 have been used to investigate the conformational dependency of the σ-bond electron delocalization of these compounds. 2À8 Some reports have dealt with branched derivatives of this substance class, which were either den-drimers 9À14 or linear silanes with branched end(More)
The receptor potential of the isolated rabbit retina was recorded between a microelectrode approximately 80 microns deep from the inner limiting membrane and a reference electrode at the receptor side. Amplitude and slope of the receptor potential and the area under it were measured as a function of increasing stimulus intensity and the amplitude and(More)
