Inclusion Criteria

Inclusion Criteria:
1. General
* The criteria for eligibility described here are intended to protect patient welfare where, for example, the administration of ketamine in the context of standardized research (i.e. pharmaco-EEG challenge) would be inadvisable or unsafe. An additional purpose is to decrease psychiatric co-morbidities that may affect the clinical phenomenology or treatment response and thus obscure findings. Further, by virtue of the eligibility criteria the investigators seek to limit variability due to demographic and other factors.
2. All subjects Inclusion Criteria:
* Male or Female ages 21-45, inclusive.
* Level of understanding sufficient to agree to all tests and examinations required by the protocol.
3. TRD patients
* Major depressive disorder (MDD) diagnosis confirmed by MINI, with major depressive episode of at least 4 weeks duration.
* MADRS score of 27 or greater.
* Meet criteria for treatment resistance, defined as 2+ unsuccessful trials of antidepressants at an adequate dose for at least 6 weeks.
* On a stable dose of all psychotropic medications (including antidepressant, antipsychotic, lithium, hypnotic, etc) for a minimum of 4 weeks prior to the Screening period.
4. MDD patients
* MDD diagnosis confirmed by the Mini International Neuropsychiatric Interview (MINI), with major depressive episode of at least 4 weeks duration.
* MADRS score of less than or equal to 12.
