Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to understand how ketamine brings about dissociative symptoms.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The goal of this proposed research is to record the effects of ketamine on brain activity to understand the changes that occur during antidepressant therapy and the side effect of dissociation. This research is designed to probe altered cognitive states associated with dissociation, depression, and other neuropsychiatric conditions.
