Background:

Understanding how the human brain compactly represents perceived stimuli is a significant challenge.
Neural manifolds offer a framework for visualizing complex brain activity patterns.

Purpose of the Study:

To develop novel techniques for constructing neural manifolds.
To represent complex visual stimuli within the brain's activity patterns.

Main Methods:

A supervised locally linear embedding method was proposed.
Magnetoencephalography (MEG) data was used to capture brain activity.
Source localization techniques were applied to MEG data.

Main Results:

A strong correlation was found between neural manifolds and face orientation in visual stimuli.
The method successfully revealed high-level information about image content from brain responses.
10x10-fold cross-validation confirmed the robustness of the findings.

Conclusions:

The proposed method is effective for investigating inherent patterns in brain activity.
This approach provides a powerful tool for understanding neural representations of visual information.
