Rats were cooled in water until attaining profound hypothermia and respiratory arrest. After removal from water, 0.5% solution of Na2EDTA was administered intravenously. This led to a drop of blood [Ca2+] by 20-30% from the baseline and promoted recovery of respiration following its arrest lasting 10.3 ± 1.4 min. By the 30th minute of Na2EDTA(More)
We studied the characteristics of evoked potentials recorded during the recognition test based on four types of series of images subjected to the wavelet filtration: images of living objects containing either low frequency or high frequency portion of the spatial frequency spectrum, and imaging of non-living objects in the same two spatial frequency bands.(More)
This paper presents a new hardware and software system that allows not only recording the EMG of different groups of the respiratory muscles but also performing its amplitude-frequency analysis to determine the change in the contribution to the function of breathing of the respiratory muscles and detect early signs of fatigue of the respiratory muscles. The(More)
The electrophysiological measurements of image distortion are based on the model of object's detection in noise which describes quantitatively frequency-contrast characteristics in presence of noise and consist of the several stages including primary filtering, signal match filtering, comparison with threshold, decision, internal and memory noise. The tools(More)
