Human umbilical tissue-derived cells (hUTC) represent an attractive cell source and a potential technology for neurorestoration and improvement of functional outcomes following stroke. Male Wistar rats were subjected to a transient middle cerebral artery occlusion (tMCAo) and were intravenously administered hUTC (N = 11) or vehicle (N = 10) 48 hrs after stroke. White matter and vascular reorgan...

In recent years, the development of neuroimaging techniques such as high-resolution magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), positron emission tomography (PET), or single photon emission tomography (SPECT) has promoted the identification of structural and functional characteristics underlying mental disorders to a great extent. In anxiety disorders, recent...

Functional Magnetic Resonance Imaging (functional MRI or fMRI) is a noninvasive neuroimaging technique that can be used for studying human brain function in vivo. Functional MRI extends the use of Magnetic Resonance Imaging to provide information about biological function in addition to the anatomical information. Seiji Ogawa first demonstrated that by measuring the blood-oxygenation-level-depe...

In this paper we present a system that allows onlinecontrol of functional magnetic resonance imaging (fMRI) experiments. With the beginning of the fMRI experiment, the functional volumes are real-time exported to an external PC. The statistical relevance of each voxel's activation is then calculated by correlation analysis. After calculation, the activation maps are overlaid to an anatomical da...

Adaptively limiting image acquisition to areas of interest will allow more efficient data acquisition time for in-depth characterization of areas of brain activation. We designed and implemented an adaptive image acquisition scheme that uses a multiresolution-based strategy to zoom into the regions of cortical activity. Real-time pulse prescription and data processing capabilities were combined...

Functional brain imaging with magnetic resonance is a useful research tool for showing regional metabolic changes with ongoing brain activity. Use of functional imaging to study the anatomy and function of various brain areas has recently been applied to the examination of the emotional life of patients including those with anxiety, panic, or depression. The application of this technology to th...
