Genetic background steers PTEN syndrome traits
People with the syndrome, caused by variants in the gene PTEN, often have autism or cancer, or both, but it depends on the genetic diversity encoded in the components of distinct cell signaling pathways, according to a new study.
Some dopamine neurons signal default behaviors to reinforce habits
Movement-sensing neurons that target the striatum influence a mouse’s choice of action by favoring routine.

Split gene therapy delivers promise in mice modeling Dravet syndrome
The new approach overcomes viral packaging limitations by delivering SCN1A piecemeal and stitching it together in target cells.

PTEN problems underscore autism connection to excess brain fluid
Damaging variants in the autism-linked gene cause congenital hydrocephalus—a buildup of cerebrospinal fluid in the brain—by turbocharging a downstream signaling pathway that promotes the growth of cells, according to a new study.

Cell ‘fingerprints’ identify distinct cortical networks
These networks align with different assemblages of cells, a finding that could reveal how cellular diversity influences brain function, according to a new study.

Neural population-based approaches have opened new windows into neural computations and behavior
Neural manifold properties can help us understand how animal brains deal with complex information, execute flexible behaviors and reuse common computations.
