In comparing gene expression profiles and SNP risk across psychiatric disorders, Michael Gandal, Daniel Geschwind and colleagues found that shared genetic risk manifests in alterations in gene networks.
Using a mouse lacking brain-localized NHE9, Edwards shows that pH gradients affect neuronal communication and autism-like behaviors.
By assessing the 16p11.2 deletion autism mouse model, Ted Abel and colleagues uncover male-specific vulnerabilities in striatal signaling and reward function.
Lauren Weiss and Erik Ullian report on two studies using carrier-derived iPSC neurons to elucidate cellular phenotypes associated with 16p11.2 CNVs and a BRAF RASopathy mutation.
Evan Eichler and Robert Darnell provide deep whole genome sequencing of 516 families with idiopathic autism, providing insights into the complex etiology of simplex autism.
Robert Malenka and colleagues find that oxytocin acts within the ventral tegmental area to increase dopamine reward neurons to reinforce the rewarding aspects of social interactions in mice.
Jun Huh, Gloria Choi and colleagues provide a link between maternal infection, gut bacteria and the risk of developing behavioral and cortical abnormalities in mice.
Christopher Gregg and colleagues demonstrate that diverse epigenetic mechanisms affect allele-specific gene expression in the mammalian brain.
Kevin Bender and Stephan Sanders show that ASD-associated SCN2A variants lead to impaired NaV1.2 channel activity and reduced neuronal excitability.
Amiel Rosenkranz and colleagues have identified a specific intra-amygdala circuit, from the lateral nucleus to the medial nucleus, which is critical for social learning.
