Cool work on conserved #MotorCortex dynamics across species. #Behavior differs mainly through different trajectories on shared #NeuralManifolds.

Just read a fantastic paper showing how dendritic morphology defines local computational subunits—letting neurons process synaptic input locally before it ever reaches the soma.
Dendrites are the brain of the neuron. 🧠✨

We first compared cerebellar #BMI control with #MotorCortex (M1)-driven BMI.
Performance was on par.
And, BMI control from the cerebellum was equally effective in healthy vs. stroke brains.

🧬 The Neuroscience Behind It
This kind of performance relies on motor intention, attention control, and working memory—functions deeply tied to prefrontal and #motorcortex activity.
That’s where #neurotechnology steps in.

Neural recording and experimental setup. Top: T1-weighted magnetic resonance imaging (MRI) showing the overlap between arm/hand movement areas (from functional MRI) in primary motor cortex and the placement of the recording array as indicated by post-operative tomography. Bottom: Rendering of the experimental setup, where the BMI user (pixelated for privacy) viewed a clock with a single hand (red dot) performing a full cycle in 2,560 ms and had to indicate when he first intended to move, when he moved (action), or when tones occurred (effect).
Movements can be initiated before or when one becomes aware of the intention. @jpnoel.bsky.social &co show that spiking activity in human primary #MotorCortex coincides with onset of subjective intention, extending prior work on pre-motor & parietal #brain areas @plosbiology.org 🧪 plos.io/4ivhobk
