RNA-binding proteins use both translational activation and repression of key molecular determinants to post-mitotically sculpt the identity and connectivity of developing mouse neocortex in an area-specific manner.
TANGO1 functions as a linactant filament to stabilize shallow COPII-coated buds, and after which membrane tension regulation, possibly mediated by TANGO1-controlled membrane fusion, facilitates bud elongation for procollagen export.
New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.

Anatomical tracing, in combination with a genetic ablation approach, identifies a critical maturation period for neocortex to dorsal raphe afferents pivotal for the development of behavioral persistence over adolescence in mice.
Genetic and imaging analysis reveal that microglial precursors use ocular blood vessels as a pathway to enter the optic cup and subsequently infiltrate the retina preferentially through the neurogenic region.

In neurons of the Drosophila brain’s memory center, PKCδ relays a post-learning dopamine signal to mitochondria, boosting their metabolic activity and thereby unlocking long-term memory formation.
Deciphering the mechanism of action of a large family of natural and synthetic cytotoxic lipids bioactivated by enantiospecific oxidation into protein-reactive species inspires the development of enzyme-specific prodrugs.
A computer model of the mouse visual cortex shows that local brain circuits are organized as switches whose states are coded as neuronal oscillations with different frequencies.

Distinct and direct functions of the RNA binding protein SAM68 regulate integrin signaling and focal adhesion dynamics that condition basement membrane deposition and angiogenic behavior of endothelial cells.

The first born excitatory cerebellar nuclei neurons influence the survival of their Purkinje cell partners which stimulate the expansion of granule cells and interneurons to produce functional local circuits.
