1. A modular physiological sensor comprising:
- an electroencephalogram (EEG) sensor comprising a stem, a left branch and a right branch;
the left branch and the right branch extending generally perpendicularly from the stem so as to form a branch intersection, wherein the branch intersection includes a left corner defined by an intersection of the left branch and the stem of the EEG sensor and a right corner defined by an intersection of the right branch and the stem of the EEG sensor;
a plurality of EEG electrodes disposed along the left branch and the right branch;
a ground electrode and a reference electrode disposed proximate the branch intersection;
a first mounting zone extending outwardly along an edge of the left corner of the branch intersection and configured for removable attachment of a first regional oximetry (rO2) sensor, said first rO2 sensor comprising a first edge including a first outline shape; and
a second mounting zone extending outwardly along an edge of the right corner of the branch intersection and configured for removable attachment of a second rO2 sensor, said second rO2 sensor comprising a second edge including a second outline shape;
wherein the first mounting zone is shaped to match at least a portion of said first outline shape; and
wherein the second mounting zone is shaped to match at least a portion of said second outline shape.

Abstract
Modular physiological sensors that are physically and/or electrically configured to share a measurement site for the comfort of the patient and/or to ensure proper operation of the sensors without interference from the other sensors. The modular aspect is realized by providing outer housing shapes that generally conform to other physiological sensors; mounting areas for attachment of one sensor to another sensor; providing release liners on the overlapping sensor attachment areas; and/or providing notches, tabs or other mechanical features that provide for the proper placement and interaction of the sensors.
