Non-saturating dimensionality, contextual dependence, and the limits of unsupervised decoding in motor cortex

The paper shows that unsupervised dimensionality in motor cortex does not reflect movement complexity but instead scales with neuron count and is context-dependent, challenging assumptions about neural representation.

Stability of neural manifolds at minimal dimensionality despite motor representational drift

The paper shows that neural manifolds remain stable in low dimensions despite motor representation drift, with encoding maps changing while latent maps stay stable.

Context-dependent low-dimensional neural dynamics unfold in distinct subspaces, dimensionality, and dynamical strength for natural walking and reaching

The paper compares neural dynamics during walking and reaching, finding that reaching has higher dimensionality and faster decay in dynamical systems than walking.

Direct comparison of epifluorescence and immunostaining for assessing viral mediated gene expression in the primate brain

The paper compares epifluorescence, immunofluorescence, and immunohistochemistry for assessing viral-mediated gene expression in macaques, finding that the latter two methods detect more transduced neurons and provide better visualization.

Embodied Cognition and Decision-Making in the Primate Superior Colliculus

This study shows that inactivating the superior colliculus in monkeys alters perceptual decision-making, supporting the embodied cognition model by linking decision evidence accumulation to a brainstem structure.
