Is there a cortical blood flow redistribution pattern related with perseverative error in schizophrenia?
Successful WCST performance is associated to a high left frontal activity in controls but not in patients. The severity of PE during WCST performance is associated to a low left frontal-temporal activity in controls and to a high right parietal-occipital activity in schizophrenia. This may represent a cortical activity redistribution pattern related to perseveration in schizophrenia.
Our study identifies enrichment in B cell-related genes in patients with COPD with emphysema that is absent in bronchiolitis. These observations contribute to a better understanding of COPD pathobiology and may open new therapeutic opportunities for patients with COPD.
