Brief Summary

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

This phase Ib study aims to evaluate applicability of touchscreen-based cognitive test battery for assessment of ketamine-induced schizophrenia-like cognitive deficits in healthy volunteers. Additionally, the study aims to assess whether ketamine-induced cognitive deficits are reversed by modafinil using touchscreen-based test battery for testing of cognition.

Detailed Description

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

Ketamine-induced schizophrenia-like cognitive deficits in healthy volunteers are measured by using touchscreen-based cognitive tests. In addition, the study aims to assess whether ketamine-induced cognitive deficits detected by touchscreen-based cognitive tests are reversed by modafinil.
