Prof Darryl Eyles is the head of the Queensland Centre for Mental Health Research Psychiatric Neurobiology laboratory. One of Darryl's research directions is focused on how known risk-factors for schizophrenia change the way the brain develops. His group have established the biological plausibility of various epidemiological risk factors for this disease including developmental vitamin D deficiency, prenatal hypoxia and maternal immune activation. Strikingly all these exposures affect the early development and later differentiation of early dopamine neurons. A second major focus is on understanding the effects of increased dopamine release in selective circuits and how this may be causal in schizophrenia. A third major interest is in factors such as the gut microbiome, and how increased testosterone contribute to altered brain function related to autism.
