Aspiration was used to selectively ablate only the lateral white matter tracts and a minimal portion of the dorsal and ventral graymatter. The frontal lobe white matter volume was significantly larger than normal and the frontal lobe graymatter showed an overall enlargement in autism. Quantitative data were collected every 50 -100 mm along a penetration until either the graymatter ended or the responses became weak or untuned. Reduced prefrontal graymatter volume and reduced autonomic activity in antisocial personality disorder. For example, the peak of a cluster may be in graymatter with an extent large enough to include surrounding white matter. The dominance and accompanying relative increase in graymatter in a particular hemisphere influences the type of cognitive processing at which that hemisphere can excel. Thus, hyperserotonemia may produce increased thickness of the graymatter in autism without affecting the white matter.

Increased graymatter volume in medication naive highfunctioning children with autism spectrum disorder. Cerebral cortical graymatter overgrowth in autism is associated with functional variation of the serotonin transporter gene. Many researchers have documented that while there are age-related decreases in graymatter in the prefrontal cortex, the overall cortical volume does not change significantly. Voxels with graymatter probability higher than 0.4 were selected. Axons but not cell bodies are activated by electrical stimulation in cortical graymatter. Patients had significantly decreased volumes in the cingulate graymatter and the amygdala compared to controls. In addition, reporter expression was detected in protoplasmic astrocytes of ventral graymatter but not in fibrous astrocytes of white matter. Reduced anterior and posterior cingulate graymatter in borderline personality disorder. This is probably because white matter reductions are more diffuse and widespread than those involving graymatter. In both studies, the reduction in white matter was slightly greater than that in graymatter. The pixels representing graymatter in the frontal cortex of one group, for example, might superimpose on frontal white matter of the other group.

By 3 weeks post-transplantation, large numbers of graft-derived cells differentiated into mature neurons in both the white and graymatter of the intact adult hippocampus, striatum, and spinal cord. They demonstrated that although there are linear increases in the development of white matter during childhood, there were nonlinear changes in the development of cortical graymatter right through adolescence. It also appears that the posterior cerebellar vermis and the volume of cerebellar graymatter are typically smaller than in age-matched healthy control subjects at the earliest ages examined. Memory and executive function in older adults: relationships with temporal and prefrontal graymatter volumes and white matter hyperintensities. At the earliest ages examined, there is an overgrowth of cerebral volume and graymatter as well as cerebral and cerebellar white matter, compared to normal. Although total brain size does not increase after 5 years, frontal cortical graymatter peaks at 12.1 years for males and at 11 years for girls. Changes in graymatter volume in patients with bipolar disorder. In the cerebellum volumes, there was one outlier among the autism parent couples, whereas in the cerebral graymatter volume there was one outlier among the healthy control couples. Patients showed a significant increase of 6 % in intracranium, total brain, cerebral graymatter, cerebellum, and of more than 40 % in lateral and third ventricles compared to controls. Thus, in two major developmental disorders of genetic origin, differences in overall cerebral volume appear to be related to the extent of connectivity (white matter) between regions (graymatter). Volume changes in graymatter in patients with schizophrenia. Impaired cerebral cortical graymatter growth after treatment with dexamethasone for neonatal chronic lung disease. This could explain why minicolumns are "narrow" or "underdeveloped" and an excess of neuron numbers could explain why cortical graymatter volumes are larger than normal. Focal graymatter density changes in schizophrenia. Bilirubin is known to accumulate in the graymatter of neurological tissue where it exerts direct neurotoxic effects.
