The white matter on the other hand primarily consists of myelinated axons and the supportive glial cells. The purpose of the white matter is to allow for communication from one part of the cerebrum to the other, and also to communicate to other brain areas and carry impulses through the ...
The white matter consists mostly of longitudinally running axons and also glial cells that surround the gray matter except for the region where the dorsal horn touches the margin of the spinal cord. The horns of the gray matter divide the white matter into three columns (funiculi): dorsal, lat...
Lifelong bilingualism may result in neural reserve against decline not only in the general cognitive domain, but also in social cognitive functioning. In this study, we show the brain structural correlates that are associated with second language age of acquisition (L2AoA) and theory of mind (the...
Subjective hyperosmia refers to a self-reported olfactory ability that is superior to a normal, intact sense of smell (normosmia), and is associated with olfactory emotional experience. The current study used voxel-based morphometry to investigate the gray matter volume (GMV) in people with self...
It consists of a parameter estimation process based on the modified kmean clustering (MKM) algorithm to estimate the parameters of SVGM from a radiologist-segmented image, and a classification algorithm based on iterated conditional modes (ICM) to perform the segmentation of the sequential brain ...
Fibromyalgia (FM) and ankylosing spondylitis (AS) are both rheumatic diseases characterized by significant musculoskeletal pain. In this study, we investigated the differences of the resting-state network (RSN) connectivity and gray matter volume (GMV) b
grayscale (redirected fromGray level) Related to Gray level:Grey scale gray·scale (grā′skāl′) n. 1.A series of shades ranging from pure white to pure black, used in displaying monochromatic images. 2.An image displayed using such a series of shades. ...
The small butterfly shaped structure of spinal cord (SC) gray matter (GM) is challenging to image and to delineate from its surrounding white matter (WM). Segmenting GM is up to a point a trade-off between accuracy and precision. We propose a new pipelin
Ellingsen stresses that an important mechanism in placebo analgesia – one that has been replicated several times – is the engagement of the opioid descending modulatory system, which consists of vmPFC, amygdala, and PAG. "When treated with a placebo that is expected to have analgesic effects,"...
The human PAG is about 14 mm long and 4–5 mm wide and consists of poorly differentiated gray matter that encircles the mesencephalic aqueduct. It extends from near the posterior commissure rostrally to the level of the locus coeruleus caudally. Contrary to its name, it does not completely en...
