Research has shed light on the genetic architecture of the human cerebellum, suggesting its importance in human evolution and psychopathology. However, the focus of the studies appears to vary, with some examining the cerebellum specifically, while others look at related aspects of brain development and morphology, including cortical folding and the hippocampal formation. The studies seem to draw from large datasets, such as the UK Biobank, to explore the genetic underpinnings of brain structure and its potential links to mental health.
