Summary Enzymatically disaggregated, electrically stimulated cardiomyocytes from adult rats were examined by television-mediated vital microscopy for intracellular Ca2+ concentration and contractile activity. Using an inverted microscope in the epifl

Anteroapical left ventricular aneurysms were produced in 23 sheep by coronary arterial ligation. Plication of the aneurysm does not change stroke volume or cardiac output and does not significantly change left ventricular oxygen consumption from the

Single bulbar respiratory unit activity was recorded in urethane-anesthetized rabbits. During artificial ventilation, reflex contractions of the diaphragm were elicited by the forced deflations of the respirator. Out of 44 neurons, four I, one E and

The property of the neuronal membrane to be permeable to metabolic modifiers of two regulatory enzymes has been utilized to manipulate the spike activity of inspiratory (I) and expiratory-inspiratory (EI) neurons of the bulbar respiratory centre. The

An amplitude window discriminator is described which permits selection of spikes from a multi-unit recording, provided the signal-to-noise ratio is high enough. The device can be built at relatively low cost and time. The circuitry permits analysis o

Expiratory-related neurons have been classified according to their phase relation within the respiratory cycle, their response to lung distension and collapse (α- and β-type), and to hyperventilation (tonic firing denoted by “+”, cessation of a

A device is described which permits to obtain a signal at the beginning of in- or expiration respectively. This signal may be used to trigger an electrical stimulator. To permit studies at different states of lung inflation the tracheal cannula is co

Suprapontine brain sites acting on the central respiratory system have been demonstrated to give rise to inspiratory as well as expiratory facilitatory effects. In the present study the inspiratory inhibitory effect which has been reported in the cat

In anesthetized rabbits spirogram and diaphragmatic activity were examined during electrical stimulation of regions of the medulla oblongata. The volleys were triggered by the animal's own respiration. 1. One volley of 120 msec duration at 100 pulses
