# Subjects

A subject represents a human being who is the subject of a [record](https://emotiv.gitbook.io/cortex-api/records), ie the person wearing the headset during the record. A subject is a permanent object. It is stored on the hard drive and then synchronized to the EMOTIV cloud.

To associate a subject to a record, you must create the subject first, by calling [createSubject](https://emotiv.gitbook.io/cortex-api/subjects/createsubject). Then you must specify the subject name when you call [createRecord](https://emotiv.gitbook.io/cortex-api/records/createrecord). A subject is identified by his/her name.

You can call [querySubjects](https://emotiv.gitbook.io/cortex-api/subjects/querysubjects) to list the subjects already created for the current user.
