First-Person Consciousness Brain Bee Ideas
Close your eyes and imagine moving your hand.
No muscle contracts, yet the brain vibrates as if the gesture were real.
This borderland — between physical movement and imagined movement — is one of the most beautiful expressions of First-Person Consciousness.
The body thinks without acting; the mind acts without body.
And still, there is energy.
There is direction, there is intention.
That energy is what I call the existential tension of the gesture — the embryonic spark of every action, every creative act.
And it is precisely this tension that Yi et al. (2025) allow us to observe, quantify, and understand more deeply than ever before.
The Study
The work by Yi et al. presents a unique multimodal dataset combining EEG (electroencephalography) and fNIRS (functional near-infrared spectroscopy) during motor imagery tasks — imagined movements of the upper limbs, performed without real motion.
The dataset includes dozens of participants, multiple motor imagery conditions, perfectly synchronized EEG and fNIRS recordings, and both high temporal and spatial resolution.
It is, so far, one of the most comprehensive open datasets for studying neurovascular and neuroelectrical coupling during mental simulation of action.
More than a technical contribution, it is an invitation to study how the mind stages the body — an inner theater where movement begins before the muscles awaken.
Motor Imagery and Zone 2
In Zone 2, body and consciousness are metabolically aligned, operating between 92% and 94% SpO₂ — the point of maximal energetic fruição and minimal cognitive resistance.
It is the state in which the brain acts effortlessly and the body thinks without tension.
An instant where intention already contains movement, though movement has not yet begun.
Motor imagery embodies precisely this phenomenon — suspended action, interiorized gesture.
The motor cortex activates, blood flows, beta and mu rhythms organize in readiness patterns — and yet the muscles remain still.
It is the brain experiencing the world without disturbing the world: a natural exercise in biological ethics and energetic economy.
Fruição and Neural Energy
During motor imagery, the body does not “pretend” to move — it lives the movement in its purest form, without the metabolic cost of execution.
This makes motor imagery a natural laboratory for Fruição: the state where action happens without strain, and feeling flows without resistance.
EEG captures the rapid oscillations of motor thought, while fNIRS maps the slow waves of hemodynamic change.
Together, they reveal that imagination is not a shadow of reality, but a more economical and intelligent mode of existence.
Electrical and vascular rhythms dance together — blood pulsing to the tempo of thought.
It is life rehearsing itself before being lived.
Tensional Selves and Plasticity
Every attempt to move — real or imagined — evokes what I call Tensional Selves: temporary neuroenergetic identities formed by the brain’s metabolism in response to a task.
They are not psychological characters, but momentary patterns of embodied organization that prepare the organism to act.
In motor imagery, we observe the tensional self of pure intention — the one that regulates, prepares, and projects the act before any physical engagement.
EEG shows its signature in mu and beta rhythms; fNIRS reveals pre-motor and supplementary motor activation.
These same circuits sustain attention, learning, and creativity.
Training these tensional configurations is to train the brain to act delicately — with precision, without waste, without aggression.
It is to transform energy into awareness.
Evidence and Applications
Yi et al. (2025) provide a major empirical foundation:
The dataset contains synchronized EEG–fNIRS recordings during multiple motor imagery paradigms;
It enables the study of neurovascular coupling between fast electrical activity and slower blood flow dynamics;
It is ideal for machine-learning models and brain–computer interfaces (BCI) that decode intention into technological action;
It supports comparative research in motor plasticity, rehabilitation, and meditative movement.
For anyone working in human neurotechnology, this dataset is gold — a transparent map of the mind in motion.
A Decolonial and Ethical Perspective
The greatest risk of brain–computer interface development is to treat the brain as a machine of command, reducing consciousness to a functional input–output system.
Decolonial Neuroscience offers a different reading:
the brain is not a tool — it is a living environment of relation.
The data from Yi et al. remind us that before a gesture is utilitarian, it is a mode of belonging.
Motor imagery is a language of care: it teaches us to act without harm, to move without domination.
This is the essence of a Neuroethics of Movement — where technology amplifies experience rather than replacing it.
Every interface must begin with respect for the Damasian Mind — the living integration of body, intention, and feeling.
EEG + fNIRS and the Future of Applied Consciousness
Within SfN 2025, this study forms a bridge between pure neuroscience and human application:
Motor imagery training and rehabilitation using real-time EEG–fNIRS feedback;
Hybrid deep learning models decoding motor intention with accuracy and ethical context;
BCIs tuned to fruição, recognizing balanced energetic states rather than binary commands.
These technologies signal a new generation of human–machine relationships: not of control, but of communion between consciousness and information.
A future where data does not replace awareness but expands it through care.
Conclusion
Yi et al. (2025) offer more than a dataset — they offer a mirror of the future.
By merging EEG and fNIRS, they reveal the instant where imagination touches biology, where the invisible architecture of thought translates into light and electricity.
For the first time, we can see with such clarity the moment the body begins inside the mind.
That instant of pure potential is the birthplace of creation, healing, and consciousness.
To train the brain to imagine is, ultimately, to train the body to belong to the world without harming it.
And within that balance lies the true meaning of human high performance.
