Gouverneur, New York — Nine brains inexplicably appeared earlier this week along a street in a St. Lawrence County village. How the brains got there and where they came from remains a mystery.

Residents discovered the brains on Beck with Street near railroad tracks and called the police.

Gouverneur police collected one of the brains and brought it to a local veterinarian for an examination, WWNY TV 7 reported. The veterinarian determined the brain had been professionally removed — likely from a dog — and preserved in formaldehyde.

The veterinarian told North Country Now that the brain was consistent with a beagle-sized brain and was in very good condition with no damage.

But a chemistry professor at Clarkson University told North Country Now the specimen was possibly from a sheep, not a dog.

Regardless, police told both news outlets there was little to fear. The nine brains are believed to have been part of a collection for educational or research purposes and no criminal activity, other than littering, is suspected, police said.

As unusual as it might seem, mishaps with preserved brains do happen. Last year the University of Texas in Austin said dozens of human brains stored in jars of formaldehyde and reported missing were actually destroyed in 2002. The brains had been donated for teaching and research.
