The HEAVEN head transplant initiative needs human data concerning the acute restoration of motor transmission after application of fusogens to the severed cord in man. Data from two centuries ago prove that a fresh cadaver, after hanging or decapitation, can be mobilized by electrical stimulation for up to 3 hours. By administering spinal cord stimulation by applied paddles to the cord or transcranial magnetic stimulation to M1 and recording motor evoked potentials, it should be possible to test fusogens in fresh cadavers. Delayed neuronal death might be the neuropathological reason.

Cephalosomatic anastomosis is made possible by the GEMINI Spinal cord Fusion protocol.[
Another possibility exists, namely, testing the fusogens on fresh cadaveric specimens. This exploits the phenomenon of delayed neuronal death and is supported by observations made two centuries ago in which electric jolts induced complex motor responses in fresh cadavers.
ELECTRICAL INDUCTION OF MOVEMENTS IN FRESH CADAVERS
In 1802, at the height of the controversy on the existence of animal electricity between Alessandro Volta (con) and Luigi Galvani (pro),[
These data prove that electrical stimulation up to 3 hours after death can engage the CNS and produce movements, in agreement with Aldini's predictions: “convey an energetic fluid to the seat of all sensations; distribute its force throughout the different parts of the nervous and muscular systems; produce, reanimate and, so to speak, control the vital forces: this is the object of my research…from the theory of galvanism.”[
In other words, it appears that a fresh cadaver might act as a proxy for a live subject as long as a window of opportunity is respected (a few hours). It also implies that the process of deathly disintegration is not an immediate process (see below). We name this effect the “Frankenstein effect.” We believe this has a neuropathological basis.
DELAYED NEURONAL DEATH AND RESISTANCE TO DEATH
It is generally believed that a neuron is highly sensitive to hypoxia or glucose deprivation, and that cerebral ischemia of more than several minutes results in irreversible brain neuron damage.[
However, this belief seems to be negated by the above-reviewed data and modern evidence. The reality is that there is no well-accepted definition of the point at which a cell dies.[

These studies refer to stroke models in animals and humans.[
EXPERIMENTATION ON FRESH CADAVERS
In view of many failed trials based on animal data, the need to acquire clinically relevant experimental data in neurology is urgent, and this also applies to spinal cord fusion protocols. Organoids (“minibrains”) have been grown for exactly this purpose.[
As a corollary, the same line of reasoning suggests that current protocols to rapidly (within the hour) freeze just-deceased heads (and/or whole bodies) for future reanimation might actually turn out to be successful, provided the de-thawing process does not damage cellular bodies.[
Both occurrences are likely due to the phenomenon of delayed neuronal death.
