A professor at Stanford has been for years investigating the impact on the brain of close encounters with UFOs.

His name is Dr. Garry Nolan.

Now, as the Pentagon dropped a new batch of UFO files, he shares an explosive insight.

Appearing on CBS, he says, officials from the government reached out to him years ago.

They needed him to analyze samples of officials suffering from the infamous 'Havana Syndrome.'

However, in those cases, Nolan found something strange.

'Damages in human brains'

The signs on scars inside their brains indicated they were in an alleged close encounter with a UFO.

"A few of them claimed," the professor claimed, "had damage that had been done to them inside their brains that was due to proximity to alleged UAPs."

Though Nolan did not squarely put blame on aliens for this, the professor shares the signs in scans show it looked like "white matter disease." 

This disease, perhaps, the professor suggests, can come from technology, the unknown object's use.

Nolan says they produce harmful radiation effects, but it is not simple like that.

Simple explanation

The professor explains it with an example.

"It’s more along the lines of, you know, if you walk across an airfield and you get in the exhaust plume of a jet engine, you’re going to get hurt." 

"So whatever it is that these objects might be using to move around in the ways that they do create some sort of local field structure or some sort."

"Let's just call it ionizing radiation, which will burn tissue," he concludes.

UFOs' new batch of files sparks a renewed interest in the question of whether aliens are real, which so far has no conclusive answers.
