|---|---|
| 1) Detecting and characterizing functional network changes in different diagnoses underlying hallucinations. Questions that are addressed are: can changes in local and global connectivity be detected in brain networks of patients with and without hallucinations for the different diagnoses? Can brain regions be identified which are more affected than others and can regional differences in network change be related to region-specific properties of the network? 2) Relating specific network changes to specific subtypes of hallucinations. If patterns of change in connectivity or regional changes in brain networks are found within or between different diagnoses, can a relationship with certain subtypes of hallucinations be established? | — |
