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.

Ketamine targets lateral habenula, setting off cascade of antidepressant effects
The drug’s affinity for overactive cells in the “anti-reward” region may help explain its rapid and long-lasting results.
