Moreover, in our study, we found that only the right PPTha interacted in the relationship between TPH2 and childhood trauma, and only the right RPhG had a main effect on CTQ; the left ones did not, potentially due to hemispheric lateralization since one study [1] demonstrated that the left thalamus was smaller than the right in both schizophrenia patients and healthy individuals. Here, TPH2 is linked to schizophrenia.
