Background:

Decoding neural signals is crucial for brain-computer interfaces (BCIs).
Current methods often struggle with the complexity of neural data during movement.
Improving decoding accuracy is essential for effective BCI applications.

Purpose of the Study:

To present a novel protocol for decoding kinematic and kinetic parameters from the primary somatosensory cortex.
To compare a state-based decoding approach with conventional methods.
To enhance the accuracy of BCIs for hand movement control.

Main Methods:

A protocol for decoding neural signals from the primary somatosensory cortex during hand movements was developed.
Data preparation and feature extraction were performed.
A state-based model classified movement directions and predicted parameters using regression (partial least squares, multilinear regression).

Main Results:

The state-based decoding approach demonstrated superior performance compared to conventional decoders.
Enhanced accuracy was achieved in decoding kinematic and kinetic parameters.
The protocol effectively classifies movement directions into distinct states.

Conclusions:

The developed state-based decoding protocol offers a significant improvement for BCI applications.
This method provides a more accurate way to decode neural signals related to hand movements.
The findings pave the way for more sophisticated and reliable neural decoding systems.
