At UHC, as in most labs, we only do painful experiments on anesthetized animals.
This theory was bolstered by the later observation that an anesthetized animal, placed in a pressure chamber, immediately regains consciousness, Dr. Weinberg said.
Briefly, in anesthetized animals kidneys were exposed and the renal artery cannulated.
Josef Breuer and Ewald Hering reported in 1868 that a maintained distention of the lungs of anesthetized animals decreased the frequency of the inspiratory effort or caused a transient apnea.
Another technique involves injecting special "beads" into the brain nuclei of anesthetized animals.
His stomach lies on his lap like an anesthetized animal, large but no longer posing a threat.
A few minutes later the anesthetized animal was on the ground, grunting and squirming.
Most recordings of the activity of single neurons in anesthetized and conscious animals are made in this way.
Atrophied spine apparatuses were observed in these animals, as well as in anesthetized animals.
The researchers also used smoke and chemicals to injure the lungs of anesthetized animals in experiments intended to simulate respiratory failure in humans.
