Power spectral analysis of inspiratory discharges of C3-C5 ventral roots in brainstem-spinal cord preparation from foetal (18 and 20 gestation days) and newborn (0-1 and 2-3 postnatal days) rats was performed. The respiratory centre perinatal development manifests itself by decreasing of respiratory rhythm variability and increasing of inspiratory burst(More)
The role of neuronal structures of the rostral ventromedullary area in regulation of central inspiratory activity, was studied. The data obtained suggests that the structures of subretrofacial area are important for the respiratory rhythm generation due to regulation of excitability of the inspiratory neurons.
The article describes a simple floating hydraulic micromanipulator of original construction which works in positive-positive pressure and provides maximum stability of the microelectrode tip concerning the neuron in the moving brain. This work is achieved by fixing of the micromanipulator on the hinged suspension bracket and by setting of it on the surface(More)
Microiontophoretic application of H+ and H+ + HCO-3 to optically monitored multipolar neurons in the caudal and intermediate bulbar chemosensitive areas increased their firing rate and induced discharges in previously "silent" neurons. A reverse effect occurred in some cases. An interrelationship was revealed between changes of the neurons redox-state and(More)
In anesthetized cats, in conditions of vagal and sinus deafferentation, the effect of bilateral cooling of portions of the medulla oblongata ventral surface on electric activity of the respiratory volley neurons, was studied. The main types of the responses were as follows: cessation or reduction of firing, transformation of the volley discharges into(More)
