Brief Summary:
Different compounds that might modify the glucose regulation in the central nervous system will be evaluated in healthy volunteers. Several examinations will be performed in order to get a detailed plan how these substances might work.

Primary Outcome Measures :
  1. Clinical assessment with several psychopathological scores for self-assessment and peer evaluation (BPRS, PANSS, SIPS, CGI, MADRS, HAM-A, SCL-90-R) [ Time Frame: Seven days ]
  2. Laboratory assessment (routine testing, "-omics", genetic analyses, endocannabinoid levels) [ Time Frame: Seven days ]
  3. Diagnostics of the cerebrospinal fluid [ Time Frame: Seven days ]
  4. fMRI scan of the brain [ Time Frame: Seven days ]

Secondary Outcome Measures :
  1. Regular evaluating of the subject's condition and ability to continue the study by CGI [ Time Frame: Seven days ]
  2. Regular laboratory testing and ECG [ Time Frame: Seven days ]
  3. Scales for the assessment of adverse events (UKU, SCL- 90-R) [ Time Frame: Seven days ]
  4. (Numbers of) SAE and AE [ Time Frame: Seven days ]
