Serotonin powers pruning of developing brain circuits in mice
Mice with microglia missing receptors for the neurotransmitter serotonin since birth have too many synapses and show social difficulties in adulthood.

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.

Getting eight arms around autism
Octopuses can solve some of the same problems as people but do so in unusual ways.

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.

David Krakauer reflects on the foundations and future of complexity science
In his book “The Complex World,” Krakauer explores how complexity science developed, from its early roots to the four pillars that now define it—entropy, evolution, dynamics and computation.

Fleeting sleep interruptions may help brain reset
Brief, seconds-long microarousals during deep sleep “ride on the wave” of locus coeruleus activity in mice and correlate with periods of waste clearing and memory consolidation, new research suggests.
