Deep brain stimulation is a powerful therapeutic approach for severe brain circuit dysfunctions that can effectively alleviate the heterogeneous symptoms characteristic of Parkinson’s disease, dystonia, Tourette’s syndrome, and obsessive-compulsive disorder. Barbara Hollunder (Lab of Andreas Horn) explains what invasive brain stimulation can teach us about the circuit architecture of the brain’s dysfunction — and which commonalities it shares with a prism.

Topiramate — an antiseizure medication prescribed to treat epilepsy as well as migraines and bipolar disorder — does not appear to increase the risk of autism spectrum disorder (ASD) among children exposed to it prenatally, according to a new study led by Harvard T.H. Chan School of Public Health.

Yu-Tzu Shih, Jason Alipio, and Amar Sahay share new research on the autism linked gene Dyrk1a.

In order for neurons to be ‘plastic’ and adapt in response to environmental stimuli, they must undergo rapid changes in gene expression. Sometimes these rapid changes can lead to DNA damage. Daniel Gilliam and Elizabeth Pollina of the Greenberg lab describe their discovery of a DNA repair pathway that neurons use to address this challenge.

Harvard Gazette article on new research from Kristen Koenig and colleagues, co-first authors Francesa R. Napoli and Christina M. Daily, applying a new live-imaging technique to watch the creation of neurons in squid embryos in almost real-time. Tracking these cells through the development of the nervous system in the retina they discovered that these neural stem cells behaved very much like those in vertebrates during nervous-system development.

Boston Children's Hospital Answers article on new research from Joseph Gonzalez-Heydrich, David Glahn, and colleagues, co-first authors Catherine Brownstein and Elise Douard (Université de Montréal) finding that children with early-onset psychosis have similar rates of deleterious copy number variants (CNVs) as children diagnosed with autism spectrum disorder. The new study suggests that all children and adolescents with a psychotic diagnosis might benefit from undergoing genetic screening.

Walsh and colleagues, first author Richard Smith, linking mutations in the gene ATP1A3 to polymicrogyria, a disease causing irregular folds and disorganized layering in the cortex, often resulting in severe developmental and intellectual disabilities.

Maria Sundberg shares new research from the lab of Mustafa Sahin on the role of a small piece of chromosome 16, called the 16p11.2 locus, in disease phenotypes of dopaminergic neurons. The team identified that RhoA pathway activation led to network dysfunction in 16p11.2 deletion neurons. Its inhibitor, Rhosin, rescued the hyperactivity of these neuronal networks. In the future, the RhoA pathway and its inhibitors may serve as potential therapeutic targets.

Erin Johnson-Venkatesh and Hisashi Umemori share their work trying to understand why X-linked PCDH19-related disorder occurs only in females, and not males – when the opposite is typical for most disorders emanating from mutations on the X-chromosome. They find that inactivation of one copy of Pcdh19 results in a molecular mismatch at hippocampal synapses, leading to functional impairments in female, but not male mice.
