Source link Reddit discussion 2. Recording Waveform The second story comes from r/neuro, where a researcher asked about an unusual waveform appearing during extracellular recordings from parietal cortex. The setup used a 64-channel probe, and the signal appeared on one channel after the electrode moved deeper into the cortex. Source link Reddit discussion 3. Learning Chunks The final story starts with a question in r/neuro about whether the brain learns by building increasingly large abstractions, using the example of learning an instrument from individual movements to complete musical phrases. The discussion connected that intuition to motor chunking, hierarchical predictive processing, and the basal ganglia’s role in stitching practiced sequences into more automatic units.

The researchers measured continuous pouring across different containers, vessels, and speed demands, then modeled the task with a stochastic control framework that included flow dynamics, energy use, and each person’s preferred idea of Despite large differences in movement paths and durations, people tended to aim for an individually stable fill level. Source link Reddit discussion 3. Alzheimer’s Trial Extensions The third story examines whether open-label extensions make Alzheimer’s antibody trials look more effective than their controlled phases, in a 2026 paper in BMJ Neurology Open. The authors simulated and compared cognitive-decline trajectories from the lecanemab Clarity-AD and donanemab TRAILBLAZER-ALZ 2 trials, paying particular attention to selective retention and the switch from double-blind treatment to open-label follow-up.
