What cortical thickness tells us?
The thickness of the cortex can be a useful measure for understanding disease progression, for identifying affected brain regions and possibly for assessing treatment. It can also be an interesting metric for studying how the normal brain develops and ages.
How is cortical thickness of the brain measured?
Measuring the cortical thickness consists in assessing, measuring the distance between the white and the grey matter. The picture hereafter shows the distance between the blue layer (grey matter exterior) and the yellow layer (referring to the white matter boundary).
Why is cortical thickness important?
In general, greater gray matter volumes in these regions of association cortex have been associated with higher IQ scores. Thus, cortical thickness may offer more insight into the relations between brain structure and intelligence than other measures (Narr et al., 2007).
What is structural graph theory?
Structural Graph Theory deals with establishing results that characterize various properties of graphs, and utilizes them in the design of efficient algorithms and other applications.
Is cortical thickness good or bad?
Recent advances in neuroimaging enable us to assess early age-related brain changes. Of particular interest is cortical thickness, which reflects the width of the cortical gray matter,9 and has been proposed to be a reliable marker of brain atrophy.
What is normal cortical thickness of the kidneys?
Linear regression was used for statistical analysis. Results: Mean cortical thickness was 5.9 mm (range, 3.2-11.0 mm). Mean length was 10 cm (7.2-12.4 cm).
How can I improve my cortical thickness?
Our data indicate that regular practice of meditation is associated with increased thickness in a subset of cortical regions related to somatosensory, auditory, visual and interoceptive processing. Further, regular meditation practice may slow age-related thinning of the frontal cortex.
Is a graph theory topology?
Graphs are one-dimensional topological spaces of a sort. When we talk about connected graphs or homeomorphic graphs, the adjectives have the same meaning as in topology. So graph theory can be regarded as a subset of the topology of, say, one-dimensional simplicial complexes.
What is the vortex in a graph?
Vortices (precise definition) A face of an embedded graph is an open 2-cell in the surface that is disjoint from the graph, but whose boundary is the union of some of the edges of the embedded graph.
What are the effects of cortical thinning?
These findings suggest that cortical thinning in the right hemisphere produces disturbances in arousal, attention, and memory for social stimuli, which in turn may increase the risk of developing depressive illness.
What is normal parenchymal thickness of kidneys?
Renal length and parenchymal thickness are valuable diagnostic parameters in urological and nephrology practice. In the adult, each kidney measures approximately 11 cm long, 2.5 cm thick, and 5 cm wide [4]. The normal parenchymal thickness range from 14-18 mm.
How can I increase my cortical thickness?
