SENSING OLFACTORY RESPONSE TO ONE OR MORE SCENTS

摘要

Disclosed is a system for sensing an olfactory response of a subject to one or more scents. The system comprises a scent delivery device for delivering the one or more scents to the subject, a respiration sensor device for detecting one or more respiratory events of the subject, an electroencephalogram (EEG) sensor array for sensing brain activity of the subject and producing therefrom an EEG signal exhibiting the olfactory response of the subject to the one or more scents, and at least one processor. The at least one processor is configured to compute the one or more respiratory events to determine one or more periods during which the subject may be responding to the one or more scents, derive, from the EEG signal, EEG data corresponding to the one or more respiration cycles of a predetermined time period, and determine the olfactory response of the subject to the one or more scents by comparing the EEG data to model EEG data representing a predetermined olfactory condition of the subject.
