Area of Science:

Neuroscience
Biomedical Engineering
Materials Science

Background:

Cortical maps detail neural responses for predicting behavior.
Existing mapping methods (EEG, fMRI, etc.) suffer from limitations like poor resolution and invasiveness.

Purpose of the Study:

To develop and validate a graphene array-based electrocorticography method for enhanced somatosensory mapping.
To overcome the limitations of current neuroimaging techniques.

Main Methods:

Utilized a novel graphene electrode array for electrocorticography.
Demonstrated the feasibility of the method in rat models for somatosensory mapping.

Main Results:

The graphene array exhibited superior biocompatibility, high spatiotemporal resolution, and a desirable signal-to-noise ratio.
Minimized tissue damage compared to traditional methods.

Conclusions:

Graphene electrode arrays offer a promising, minimally invasive alternative for high-resolution brain mapping.
The protocol is adaptable for mapping various cortical areas, including auditory, visual, and motor cortices, with potential for clinical translation.
