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.
