- Brain maturation in adolescence: concurrent changes in neuroanatomy and neurophysiologyThomas J Whitford
Brain Dynamics Centre, Westmead Millennium Institute, University of Sydney, Westmead Hospital, New South Wales, Australia
Hum Brain Mapp 28:228-37. 2007..We suggest that the reduction in gray matter primarily reflects a reduction of neuropil, and that the corresponding elimination of active synapses is responsible for the observed reduction in EEG power...

Schizophr Res 99:182-91. 2008..We determined the presence of separable factors of general and social cognition, their equivalence to the consensus domains identified by the NIMH MATRICS project, and their effectiveness in predicting real world functional outcomes...

Neuroscience Institute of Schizophrenia and Allied Disorders, Darlinghurst, NSW 2010, Australia
Schizophr Res 90:284-94. 2007..In this study we tested the hypothesis that schizophrenia is characterized by abnormal functional connectivity in the amygdala network underlying fear perception...
