There can be no doubt that schizophrenia is associated with a variety of neurophysiological disturbances and disordered cognitive functioning. But we are only beginning to identify which brain areas are involved and to discover how abnormalities in these areas are related to abnormal psychological processes. This symposium, organised by Drs David and Cutting, offered an opportunity to learn about the work of both psychologists and psychiatrists in this field. Diverse research presented ranged from PET studies to the analysis of home videos, from epidemiological work to studies of cognitive performance.
