🐭🎶 New paper by Isko et al, who study #Alston’s singing mouse, a rodent with loud, stereotyped songs.
Using bulk tracing, serial #2P #tomography, & #MAPseq of >76,000 barcoded neurons, they find expanded projections from #orofacial #MotorCortex to #auditory #cortex & #PAG. This suggests that singing / #Vocalization may emerge not from entirely new circuits, but from selective strengthening of existing motor, auditory & vocal-control pathways.

How does somatosensory input to the #MotorCortex contribute to limb movement? This study shows that loss of #somatosensory inputs disrupts voluntary forelimb movements & motor cortex neuronal dynamics, highlighting the role of somatosensory input in motor control @PLOSBiology https://plos.io/3QcbXph

🧠 New work by Codol et al. who show that #MotorCortex dynamics are remarkably conserved across #mice, #monkeys, and #humans. Despite very different #behaviors, #NeuralPopulation activity follows similar dynamical rules on low-dimensional #manifolds. Species differences arise mainly from the geometry of trajectories within this shared #DynamicalSystem.

There's a great talk by Juan Gallego on how low-dimensional #NeuralManifolds arise from biological constraints, remain invariant across states and inputs, and support cross-animal alignment. Examples span #HeadDirection rings, #gridcell tori, #MotorCortex prep vs movement, striatal timing dynamics, and C. elegans #behavior loops. Cool talk as it shows how #manifold-level structure can generalize across tasks and organisms.

🧠 New preprint by Codol et al. (2025): Brain-like #NeuralDynamics for #behavioral control develop through #ReinforcementLearning. They show that only #RL, not #SupervisedLearning, yields neural activity geometries & dynamics matching monkey #MotorCortex recordings. RL-trained #RNNs operate at the edge of #chaos, reproduce adaptive reorganization under #visuomotor rotation, and require realistic limb #biomechanics to achieve brain-like control.

🧠 New preprint by Kashefi et al. (2025): High-density #Neuropixels recordings in monkeys reveal compositional #NeuralDynamics in #MotorCortex. A posture subspace anchors fixed points, rotational dynamics link them to generate movement, and a uniform shift tracks trial state. Recurrent models show this geometry emerges only when controlling a full arm, suggesting posture-dependent control as a core principle:

Movements can be initiated before or when one becomes aware of the intention. This study shows that spiking activity in human primary #MotorCortex coincides with onset of subjective intention, extending prior work on pre-motor & parietal #brain areas @PLOSBiology https://plos.io/4ivhobk
