Neuroscience Daily for 20 September: Brain Progenitor Lineages, Fly Connectome Model, Touch-Guided Landing

Neuroscience Daily for 20 September follows 3 stories from r/neuro and r/neuroscience, moving through brain progenitor lineages, fly connectome model, touch-guided landing. Chapters 00:00:00 — Intro 00:00:07 — Brain Progenitor Lineages 00:01:08 — Fly Connectome Model 00:01:58 — Touch-Guided Landing 00:02:47 — Closing 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.

The system combines screen vision, modeled neural activity, a learned controller, and an embodied fly model that presses keys through contact. Source link Reddit discussion 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. Source link Reddit discussion Episode closing.
