Complete Map Of Brain Activity
Summary and Analysis: "For The First Time Ever We Have A Complete Map Of Brain Activity, And It’s Dazzling" by Rachael Funnell This groundbreaking article highlights a major leap in neuroscience: the creation of the first comprehensive, brain-wide map of neural activity during decision-making in mammals. Led by the International Brain Laboratory (IBL) — a global collaboration of 12 neuroscience labs — researchers have produced an unprecedented view of how the brain functions at the single-cell level during cognitive tasks. --- 🔬 Key Achievements: - **Scale of Data**: Over **75,000 neurons analyzed**, with recordings from **over 500,000 neurons** across **279 brain regions**. - **Coverage**: Captured activity from **95% of the mouse brain volume**, offering a near-complete picture of brain-wide dynamics. - **Technology Used**: Advanced **Neuropixels probes**, which allow high-resolution, real-time recording of electrical activity from thousands of neurons simultaneously. - **...
