With thanks to Mendel, above (sorry, I can't find a way of posting a 'Quote' link in "edit").
Politico.com, Lara Seligman. 09-03-23 (9th March), "The Pentagon is funding experiments on animals to recreate 'Havana Syndrome"
Quote from the above source,
"DoD spokesperson Lt. Cmdr. Tim Gorman confirmed that the grant to Wayne State University, with collaborators from the University of Michigan, “will develop and test a novel laboratory animal model to mimic mild concussive head injury.”
“Behavioral, imaging, and histological studies will determine if the model is comparable to the abnormalities seen in humans following concussive head injury,” Gorman said, adding that: “The model may subsequently be used to test potential treatments to alleviate the deficits associated with traumatic brain injury.” "
Concussive head injury is obviously of legitimate interest to the medical profession, including those caring for wounded service personnel (as is the wider field of traumatic brain injury).
Hypothetical EMF weapons would not cause direct concussive injury, unless focussed emissions cause proximal blast effects on-target.
Concussion requires an application of kinetic energy; EMF devices do not directly deliver significant kinetic energy.
An animal model of concussion- injury resulting from rapid forced acceleration/ deceleration of the head- would appear to be a poor model for EM radiation injury, presumably resulting from heating or ionization effects.
If one wanted to have an animal model of EMR-induced injury in humans, exposing animals to EMR would have fewer confounding variables.
Lt. Cmdr. Gorman, the government / defence source cited in the Politico article, does not mention RF waves, any other EMF radiation, or "Havana syndrome". He does refer to "AHI", anomalous health incidents, a phrase which seems to have become a shorthand for symptoms reported by US embassy staff claiming to have experienced "Havana syndrome", but the term AHI could be applied to many other things.
Maybe the DoD is researching whether "anomalous health incidents" reported by those with Havana syndrome are actually sequelae of earlier events unconnected with current (or recent) employment, e.g. post-concussion syndrome.
Edited to add: Would like to make clear that I am NOT in favour of animal experiments in the context of "Havana syndrome". I don't believe that there is anything like sufficient evidence of EMR-induced injury to justify the inevitable suffering and despatch of animals.
