Dynamic causal modelling parameters from the best fitting model
| Group; mean ± SD* | |||
|---|---|---|---|
| Connectivity | Control n = 19 | FEP, treated n = 12 | FEP, untreated n = 17 |
| Right insula– ACC† | 0.1867 ± 0.3064‡ | 0.0651 ± 0.1567 | −0.0642 ± 0.2877 |
| Left insula– ACC | 0.0976 ± 0.3138 | 0.1182 ± 0.2234 | 0.1879 ± 0.4933 |
ACC = anterior cingulate cortex; FEP = first-episode psychosis; SD = standard deviation.
↵* Modulatory effect induced by high-probability reward cues.
↵† F2,47 = 3.823, p = 0.029 for analysis of variance, and p = 0.025 (healthy controls > untreated FEP) for Bonferroni-corrected post hoc t test.
↵‡ Significant t tests within each group compared with 0 (p < 0.05).
