Alterations in inhibitory circuits and difficulties in social recognition characterize mice missing one copy of DYRK1A, a gene linked to autism.

After 10 years of work, Neurona may have the data to quiet its skeptics. But its ongoing clinical trial will be the ultimate test.

Over one hour, a particularly motivated mouse poked its nose 350 times into a hole in the test chamber in the hopes of meeting a playmate.

The map, by far the largest one of an entire brain to date, contains 130,000 neurons and 53 million synapses.

Knocking down the gene that codes for the proteins normalizes the vocalizations.

The discovery could help clinicians diagnose children who carry mutations in the gene, called SCN2A, and gauge their responses to potential therapies.

Mice with microglia missing receptors for the neurotransmitter serotonin since birth have too many synapses and show social difficulties in adulthood.

The map diagrams more than half a million neuronal connections in the first complete connectome of Drosophila and holds clues about which brain architectures best support learning.

Altered expression of TSC2 and the mTOR pathway reshape the formation of certain synapses between inhibitory and excitatory neurons in mice.
