BRAIN DEVELOPMENT,
NEUROCOGNITION
& PSYCHOTIC-LIKE EXPERIENCES
Our neuroimaging findings (those that come from an analysis of magnetic resonance brain imaging (MRI) data) have revealed differences in the area of the brain known as the hippocampus in young people who report psychotic-like experiences. The hippocampus is a complex structure and processes memory and spatial information before transmitting it throughout the brain. In particular, it transmits information to areas of the brain that involve emotional, behavioral and cognitive processing. In our study, on average, the hippocampus in young people who reported psychotic-like experiences was smaller than those who did not report these experiences. We have also found areas of increased activity in the motor network and between the auditory network and visual regions of the brain. Our brain imaging findings may be related to our complementary finding that young people who report psychotic-like experiences have some neurocognitive deficits, particularly in the area of speed of processing. This, in turn, may help to explain our related finding that psychotic-like experiences are associated with an increased risk of educational and vocational difficulties.
