[PDF][PDF] Neural manifolds for the control of movement
The analysis of neural dynamics in several brain cortices has consistently uncovered low-dimensional
manifolds that capture a significant fraction of neural variability. These neural …

Rethinking brain-wide interactions through multi-region 'network of networks' models
Highlights • Brains can be viewed as a composition of anatomically distinct modules called
regions. • Brain regions interact in complex ways to form a ‘network of networks’. • Untangling …

Long-term stability of cortical population dynamics underlying consistent behavior
Animals readily execute learned behaviors in a consistent manner over long periods of time,
and yet no equally stable neural correlate has been demonstrated. How does the cortex …

[HTML][HTML] Cortical population activity within a preserved neural manifold underlies multiple motor behaviors
Populations of cortical neurons flexibly perform different functions; for the primary motor
cortex (M1) this means a rich repertoire of motor behaviors. We investigate the flexibility of M1 …

Machine learning for neural decoding
Despite rapid advances in machine learning tools, the majority of neural decoding approaches
still use traditional methods. Modern machine learning tools, which are versatile and …

A spinal cord neuroprosthesis for locomotor deficits due to Parkinson's disease
…, C Moerman, F Raschellà, S Sun, MG Perich… - Nature Medicine, 2023 - nature.com
People with late-stage Parkinson’s disease (PD) often suffer from debilitating locomotor
deficits that are resistant to currently available therapies. To alleviate these deficits, we …

[PDF][PDF] A neural population mechanism for rapid learning
Long-term learning of language, mathematics, and motor skills likely requires cortical
plasticity, but behavior often requires much faster changes, sometimes even after single errors. …

[HTML][HTML] Preserved neural dynamics across animals performing similar behaviour
Animals of the same species exhibit similar behaviours that are advantageously adapted to
their body and environment. These behaviours are shaped at the species level by selection …

Rapid adaptation of brain–computer interfaces to new neuronal ensembles or participants via generative modelling
For brain–computer interfaces (BCIs), obtaining sufficient training data for algorithms that map
neural signals onto actions can be difficult, expensive or even impossible. Here we report …
