Background:

Brain-computer interfaces (BCI) traditionally use cerebral electroencephalography (EEG), collecting limited brain interaction data.
The cerebellum, involved in movement and executive function, remains largely unexplored for BCI applications.
Investigating cerebellar electrocerebellography (ECeG) offers potential for novel BCI signal acquisition.

Purpose of the Study:

To identify key movement-related features in ECeG for decoding.
To compare the decoding performance of ECeG with conventional EEG from the cerebrum.
To assess the feasibility of ECeG as a signal source for BCI.

Main Methods:

Collected ECeG and EEG data from six healthy adults during movement tasks.
Utilized electromyography to record muscle activity.
Employed support vector machines for decoding movement vs. rest and movement vs. movement states.
Applied re-referencing techniques to mitigate artifacts.

Main Results:

Movement-related features were successfully decoded from both cerebellar and cerebral signals.
Classification accuracies for movement vs. rest were comparable (cerebrum: 0.78, cerebellum: 0.70).
Classification accuracies for movement vs. movement were also similar (cerebrum: 0.76, cerebellum: 0.71).
The delta frequency band (1-3 Hz) proved most effective for decoding.

Conclusions:

Demonstrated the feasibility of using ECeG for movement-related signal acquisition in BCI.
ECeG signals closely resemble EEG signals, providing an alternative BCI approach.
This offers a viable option for BCI when cerebral signals are compromised due to disease or injury.
