A recurrent neural network for closed-loop intracortical brain–machine interface decoders
Recurrent neural networks (RNNs) are useful tools for learning nonlinear relationships in time
series data with complex temporal dependences. In this paper, we explore the ability of a …

[HTML][HTML] Single-trial dynamics of motor cortex and their applications to brain-machine interfaces
Increasing evidence suggests that neural population responses have their own internal drive,
or dynamics, that describe how the neural population evolves through time. An important …

[HTML][HTML] Making brain–machine interfaces robust to future neural variability
A major hurdle to clinical translation of brain–machine interfaces (BMIs) is that current decoders,
which are trained from a small quantity of recent data, become ineffective when neural …

A low-power band of neuronal spiking activity dominated by local single units improves the performance of brain–machine interfaces
The large power requirement of current brain–machine interfaces is a major hindrance to
their clinical translation. In basic behavioural tasks, the downsampled magnitude of the 300–…

A high performing brain–machine interface driven by low-frequency local field potentials alone and together with spikes
Objective. Brain–machine interfaces (BMIs) seek to enable people with movement disabilities
to directly control prosthetic systems with their neural activity. Current high performance …

Latent factors and dynamics in motor cortex and their application to brain–machine interfaces
In the 1960s, Evarts first recorded the activity of single neurons in motor cortex of behaving
monkeys ( Evarts, 1968 ). In the 50 years since, great effort has been devoted to …

[PDF][PDF] Motor cortical visuomotor feedback activity is initially isolated from downstream targets in output-null neural state space dimensions
Neural circuits must transform new inputs into outputs without prematurely affecting
downstream circuits while still maintaining other ongoing communication with these targets. We …
