1. Brain Progenitor Lineages
A Nature Neuroscience study asks whether the developing brain comes from one common progenitor or from separate cell lineages. In mouse embryos, the researchers traced two neural ectoderm progenitors emerging during gastrulation: one associated with the forebrain and midbrain, the other with the hindbrain.

2. Fly Connectome Model
A post in the neuro community introduces FlyLab, a computer-based fruit fly that uses a real fly connectome in a keyboard-typing loop. The system combines screen vision, modeled neural activity, a learned controller, and an embodied fly model that presses keys through contact.

3. Touch-Guided Landing
A bioRxiv preprint investigates how touch helps fruit flies switch from flying to landing. Researchers found that touching a fly’s lower legs reliably stopped flight, while the first contact prompted coordinated movements between its legs.
