Grey matter consists of neuron cell bodies, crucial for processing information in the brain. White matter contains myelinated axons, facilitating communication between different brain regions.

我认为灰白的头发使你看上去很有尊严。4.It can be black, white or grey.它可能是黑的、白的或灰的。5.You're wearing well ─ only a few grey hairs!你一点儿都不显老，只是有几根灰白头发！gray 1.The mud is smooth, gray, soft, and plastic as butter.这种泥浆呈灰色，它光滑、柔...

Twenty-one ADHD children were examined by single voxel 1H-magnetic resonance spectroscopy (MRS) before and after 2 months of medication with OROS methylphenidate (n=10) or atomoxetine (n=11). The spectra were taken from the dorsolateral prefrontal cortex (DLPFC, 8ml) and white matter behind ...
We present preliminary data using this approach to visualize the boundaries of the cortex from the dura to the white matter. A series of isosurfaces were extracted from a signal-enhanced T1 MRI. The lower MR-intensity isosurfaces featured cortical vessels and dura, in contrast to higher ...
fact, the largest concentration of iron the researchers found was in the superficial white matter in regions of the frontal cortex, which happens to be the slowest developing structure in the human brain. Incredibly, the human frontal cortex is not fully myelinated until the forth decade of ...
Consequently, the timing and synchronization of white and grey matter maturation is disturbed. There appears to be a "false start" of some maturational processes in WM triggered by physiological and/or stimulatory events after birth. This may contribute not only to the greater risk of long-term ...
We have extended a mathematical model of gliomas based on proliferation and diffusion rates to incorporate the effects of augmented cell motility in white matter as compared to grey matter. Using a detailed mapping of the white and grey matter in the brain developed for a MRI simulator, we have...
