Background:

Shared control is a key strategy for neuroprosthetic devices, requiring accurate prediction of user goals.
Decoding grasp types is crucial for daily independence in amputees, but has not been explored using non-invasive brain activity.
Electroencephalography (EEG) offers a non-invasive method to potentially capture neural signals related to motor intentions.

Purpose of the Study:

To investigate the feasibility of using electroencephalography (EEG) to decode different grasp types from brain activity.
To determine if neural signals can predict intended grasp types for advanced neuroprosthetic control.
To assess the temporal dynamics of grasp-type information in brain activity relative to movement onset.

Main Methods:

Non-invasive electroencephalography (EEG) recordings were acquired from participants.
Machine learning algorithms were employed to decode intended grasp types from the recorded EEG data.
Analysis focused on identifying predictive information present in brain activity before and during grasping movements.

Main Results:

Electroencephalography (EEG) signals contain information that allows for the decoding of intended grasp types.
The information about the intended grasp type increases progressively during the grasping movement.
Grasp type information was significantly decodable from EEG data up to 200 milliseconds before the onset of the physical movement.

Conclusions:

Electroencephalography (EEG) is a feasible modality for extracting information about intended grasp types in the context of neuroprosthetic control.
Predicting grasp intentions from brain activity prior to movement onset is possible, paving the way for more intuitive prosthetic control.
This research supports the development of advanced neuroprosthetic systems that can enhance functional independence for individuals with limb loss.
