Simultaneous visual detection and identification: theory and data.

A signal-detection model is presented for the two-alternative forced-choice procedure that gathers simultaneous detection and identification judgments. By using vector representation, a measure of independent processing within the visual system is derived. The independence measure is applied to data on the detection and identification of stimuli that differ along the dimensions of orientation, spatial frequency, and size. Data are presented that favor the signal-detection model over a high-threshold model.

[Immunological concepts of the etiology of EPH-gestosis].

Immunofluorescent findings are revealing EPH-gestosis as an immunological disease similar to graft rejection. Deposits of immunoglobulins, complement, and fibrinogen/fibrin are localized in the glomerular capillaries, mesangium of the kidney and in the decidual arteries resembling findings in transplanted organs with signs of rejection. Fibrinoid changes of the villous stroma are found in greater amounts in placentae after gestosis revealing a more lively humoral reaction of the immune system. By mixed lymphocyte culture a cellular hyperreactivity of the mother against her fetus can be demonstrated. In conclusion, gestosis is a disease of humoral and cellular hyperreactivity finally resulting in the well-known peripheral symptoms edema, hypertension, and proteinuria. Early diagnosis followed by an effective therapy is desirable in preventing these secondary effects.

Bandwidths of orientation channels in human vision.

The ability of observers to discriminate between stimuli differing in orientation was measured using low contrast, foveally viewed stimuli. Detection and discrimination performance were measured simultaneously. A model is presented which permits bandwidths of orientation-tuned mechanisms to be estimated from the data. In a group of five observers, half-amplitude bandwidths varied from 10 degrees to 20 degrees.

Granulation tissue in the umbilical cord.

The development of granulation tissue in the umbilical cord is described here for the first time. Nothing is known about the conditions necessary to produce such tissue.
