The exploration of alternative therapeutics for hard-to-treat mental health disorders has brought into focus an array of psychedelics such as psilocybin, present in ‘magic mushrooms’, and LSD, substances once associated more with counterculture than clinical practice. Alongside ‘atypical’ psychedelics like ketamine and MDMA, these substances are increasingly being recognised for their potential therapeutic attributes.

The Constant Chatter of Neurons

“The brain isn’t like a computer that turns off when it’s not doing a particular task”, explains Alfonso Renart, the senior author of the study published in eLife. “There’s always a kind of background hum, a baseline activity that can sometimes make it seem as if the brain is chattering to itself”. The team’s study lifts the lid on how that baseline activity, the continuous stream of electrical impulses sent by neurons, impacts behaviour and decision-making.
