This paper changed my life: A technical breakthrough for memory studies

In a 2007 Science paper, Mark Mayford and his colleagues found that some neurons activated during learning are also recruited during memory retrieval. Noelia Weisstaub shares how this study and others drove an era of great progress in tool development.

Research image of serotonin and dopamine neurons manipulated simultaneously in mice.

Dopamine ‘gas pedal’ and serotonin ‘brake’ team up to accelerate learning

Mice learn fastest and most reliably when they experience an increase in dopamine paired with an inhibition of serotonin in their nucleus accumbens, a new study shows, helping to resolve long-standing questions about the neuromodulators’ relationship.

Tripping over the potential of psychedelics for autism

Drugs such as LSD act primarily on the serotonin system, which is implicated in autism — and some autistic people who experiment with psychoactive compounds report enhanced social connections, among other benefits. But researchers have more questions than answers.
