How do you know if a mouse is on a psychedelic? It might just shake its head. This behavior, known as the head-twitch response, signals whether a molecule is a psychedelic-like hallucinogen. Head twitch is one tool used by pharmaceutical companies racing to develop new mental health drugs. But does a mouse experience an altered state like a human? Do animals have mystical experiences? And what can we really learn about the brain, or even human consciousness, from these unwitting rodent

Altered States ·

2024/10/09

When journalist Anna Silman started reporting on ketamine five years ago she did so because people in her friend group had begun taking the drug recreationally. She was intrigued by the ways that interest in psychedelic-assisted therapy meant more people were taking ketamine, both with a prescription and without one too.
