In this study the cross-sectional area (in n = 14 female controls, 15 male controls, 11 female patients with schizophrenia, 15 male patients with schizophrenia) and fibre composition (in n = 11 female controls, 10 male controls, 10 female patients with schizophrenia, 10 male patients with schizophrenia) of the corpus callosum in post-mortem control and(More)
OBJECTIVE Voxel-based morphometry is a method for detecting group differences in the density or volume of brain matter. The authors reviewed the literature on use of voxel-based morphometry in schizophrenia imaging research to examine the capabilities of this method for clearly identifying specific structural differences in patients with schizophrenia,(More)
Schizophrenia is associated with structural changes (eg, a mild degree of ventricular enlargement) in the brain, although whether these precede onset of illness or progress with episodes is not established. In a postmortem study, we find that ventricular enlargement affects the posterior and particularly the temporal horn of the lateral cerebral ventricle.(More)
This review highlights the importance of right hemisphere language functions for successful social communication and advances the hypothesis that the core deficit in psychosis is a failure of segregation of right from left hemisphere functions. Lesion studies of stroke patients and dichotic listening and functional imaging studies of healthy people have(More)
Population variation in handedness (a correlate of cerebral dominance for language) is in part genetic and, it has been suggested, its persistence represents a balanced polymorphism with respect to cognitive ability. This hypothesis was tested in a sample of 12,770 individuals in a UK national cohort (the National Child Development Study) by assessing(More)
BACKGROUND In light of evidence for deviations in asymmetry and alterations in the anatomy of the corpus callosum in schizophrenia, this study examined the anterior commissure in post mortem brains (n = 14 female control patients, 15 male control patients, 11 female schizophrenic patients, 15 male schizophrenic patients). METHODS Measures were made of the(More)
Schizophrenic illnesses occur with approximately the same incidence in all human populations with a characteristic distribution (slightly earlier in males) of ages of onset. Given that the predisposition (which presumably is genetic) is associated with a procreative disadvantage why do such illnesses persist? Here it is suggested that these conditions are a(More)
Those who as adults will be admitted to a psychiatric ward with a psychotic illness can be distinguished (on the basis of group differences) from others by their behaviour and academic performance at the ages of 7 and 11 years. Pre-schizophrenic boys are anxious and hostile towards adults and peers at the age of 7 years and show poor concentration. By age(More)

The central paradox of schizophrenia is that the condition, apparently genetic in origin, persists in spite of a substantial fecundity disadvantage. The hypothesis is proposed that the predisposition to schizophrenia is a component of Homo sapiens-specific variation associated with the capacity for language. A genetic change (the 'speciation event',(More)
