Gray Matter Axonal Connectivity Maps
Structural brain connectivity is generally assessed through methods that rely on pre-defined regions of interest (e.g., Brodmann's areas), thus preventing analyses that are largely free from a priori anatomical assumptions. Here, we introduce a novel and practical technique to evaluate a voxel-based measure of axonal projections connecting gray matter tissue [gray matter axonal connectivity map...
متن کاملAbnormal structural and functional brain connectivity in gray matter heterotopia.
PURPOSE Periventricular nodular heterotopia (PNH) is a malformation of cortical development associated with epilepsy and dyslexia. Evidence suggests that heterotopic gray matter can be functional in brain malformations and that connectivity abnormalities may be important in these disorders. We hypothesized that nodular heterotopia develop abnormal connections and systematically investigated the...
متن کاملGray coding planar maps
The idea of (combinatorial) Gray codes is to list objects in question in such a way that two successive objects differ in some pre-specified small way. In this paper, we utilize β-description trees to cyclicly Gray code three classes of cubic planar maps, namely, bicubic planar maps, 3-connected cubic planar maps, and cubic non-separable planar maps.
متن کاملNeuronal and axonal loss in normal-appearing gray matter and subpial lesions in multiple sclerosis.
Multiple sclerosis (MS) is a demyelinating and neurodegenerative disease of the CNS. Multiple sclerosis lesions include significant demyelination of the gray matter, which is thought to be a major contributor to both physical and cognitive impairment. Subpial (Type III) lesions are the most common demyelinated cortical lesions. We investigated neurodegenerative features of subpial lesions in ce...
متن کاملMyelin loss and axonal ion channel adaptations associated with gray matter neuronal hyperexcitability.
Myelination and voltage-gated ion channel clustering at the nodes of Ranvier are essential for the rapid saltatory conduction of action potentials. Whether myelination influences the structural organization of the axon initial segment (AIS) and action potential initiation is poorly understood. Using the cuprizone mouse model, we combined electrophysiological recordings with immunofluorescence o...
