Human Brain Mapping based on COLD Signal Hemodynamic Response and Electrical Neuroimaging
To understand ‘Working of Human Brain’, measurements related to the brain function are required. These measurements should be possibly non-invasive. Brain should be disturbed as less as possible during the measurement. Integration of various modalities plays a vital role in understanding the cognitive and the behavioral changes in the human brain. It is an important source of converging evidenc...
متن کاملHuman brain mapping : Hemodynamic response and electrophysiology q
In view of the recent advance in functional neuroimaging, the current status of non-invasive techniques applied for human brain mapping was reviewed by integrating two principles: hemodynamic and electrophysiological, from the viewpoint of clinical neurophysiology. The currently available functional neuroimaging techniques based on hemodynamic principles are functional magnetic resonance imagin...
متن کاملElectrical neuroimaging based on biophysical constraints.
This paper proposes and implements biophysical constraints to select a unique solution to the bioelectromagnetic inverse problem. It first shows that the brain's electric fields and potentials are predominantly due to ohmic currents. This serves to reformulate the inverse problem in terms of a restricted source model permitting noninvasive estimations of Local Field Potentials (LFPs) in depth f...
متن کاملMapping human brain capillary water lifetime: high‐resolution metabolic neuroimaging
Shutter-speed analysis of dynamic-contrast-agent (CA)-enhanced normal, multiple sclerosis (MS), and glioblastoma (GBM) human brain data gives the mean capillary water molecule lifetime (τ(b)) and blood volume fraction (v(b); capillary density-volume product (ρ(†)V)) in a high-resolution (1)H2O MRI voxel (40 μL) or ROI. The equilibrium water extravasation rate constant, k(po) (τ(b)(-1)), average...
متن کاملNeuroimaging and cartography: mapping brain tumors.
Although MR images are currently of exquisite resolution, as neuroradiologists we all acknowledge that confidently mapping the margins of primary brain tumors is very difficult. Malignant gliomas tend to extend beyond their enhancement into areas of high T2 signal that most of us initially assume to represent edema. This behavior is typical of primary gliomas, and at our institution, if proton ...
