Serotonin initiates earliest social bonds
Mice and rats, for example, gravitate toward their mother’s bedding over bedding that is clean or smells of a different dam.

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.

Serotonin shapes social memory signals
Social memory, which may be altered in autism, depends on serotonin-sensitive neurons that send signals from the medial septum to the hippocampus.

Drugs boost serotonin, socialization in multiple autism mouse models
The finding that MDMA and an experimental serotonin agonist increase sociability across six different model mice suggests that disparate autism-linked mutations converge on the same underlying pathways.

After 60 years, scientists are still trying to crack a mysterious serotonin-autism link
The high levels of serotonin seen in the blood of some autistic people have confounded scientists for more than half a century. Despite so little progress, some researchers refuse to give up.

Sensor helps scientists spy on serotonin activity in mice in real time
A glowing protein tracks serotonin levels and location in the brains of living mice and could yield clues to the neurotransmitter’s role in autism.
