An Analysis Of The Relationship Between Neuronal And Haemodynamic Responses To Stress From Simultaneous Recordings Of Optical Topography And EEG Signals
Bibliographic record
Abstract
Physiological studies had been done extensively by researchers in evaluating human stress using Electroencephalogram (EEG). However, the usage of Optical Topography (OT) to evaluate the human stress is still a new field. EEG has been an established measuring device for stress through the electrical response arising from neuronal activities. On the other hand, the haemodynamic response due to stress has yet been studied. This project analyses the simultaneous recordings of the EEG and OT in response to mental stress. Data was recorded from 12 subjects that underwent tasks based on Montreal Imaging Stress Task in order to invoke mental stress. The EEG and OT datasets were analysed through the power spectrum and oxyhaemoglobin level respectively. The alpha power band has been found to be lower in the control session compared to the stress sessions. While for the OT, the oxyhaemoglobin level has been higher in the control session compared to the stress sessions. The results are then used for correlation with the data from the OT. From the correlation result obtained, it showed little significant relationship between the neuron and haemodynamic response due to stress.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
