Here is further information from Dr. Kevorkian’s book about wholesale beheadings and the doctors fascinated by their own experiments and the belief that consciousness persists after decapitation:
The same Italian investigator had done prior testing on severed heads in Bologna.
There he had noted that electrical contact on the lips caused a small amount of saliva to flow from the mouth. When touched to the exposed surface of the brain, all facial muscles contracted. Direct contact wit the electrodes to the optic and olfactory nerves gave no reaction.
Instead of supplying answers to the question of persistence of consciousness in severed heads, this kind of experimentation merely polarized the controversy and broadened the scope of activity.
Those who insisted that consciousness did persist in a severed head (even for up to a quarter of an hour) were encouraged by results from an execution in Breslau, Germany, on the morning of 25 February 1803.
Immediately after the criminal was beheaded by sword, an electrical device produced strong muscular contractions in the head. Two assistants held the head firmly while the researcher stared intently at the face.
At the same time the cut end of the spinal cord was touched with a mechanical probe. The facial muscles contracted and the lips twisted. It looked like a grimace of pain. When the researcher swiftly thrust his finger toward the open eye of the detached head, its lids closed as though the brain were conscious of an immediate threat.
The eyelids also closed when the head was faced toward the sun.
Next, the investigator shouted the victim’s name into an ear. The eyelids opened, and the gaze slowly turned toward the source of the sound. The mouth made movements as though trying to open and speak. A local merchant who was timing the various phases of the experiment announced that one and a half minutes had elapsed at the end of the hearing test.
Galvanic stimulation was repeated, and muscular reaction was now weaker. However, deep mechanical probing of the spinal cord yielded facial contortions so violent as to cause many to shout, “He’s alive!”
The eyelids slammed shut, and they were further compressed by muscular spasms that puffed the cheeks as though in pain. Teeth clamped down on fingers inserted into the mouth of the severed head, and even more forcefully with repeated probing of the spinal cord.
Another independent experiment of this kind in the same years revealed traces of muscular activity for more than an hour after decapitation.

He’s alive!?! Doctors actually thought a decapitated head was alive. Hard to believe they represented the educated. Definitely, the sanctity of life and death meant absolutely nothing to those doctors who used dead bodies like they were dispensable lab rats.
