Multimodal neurofeedback estimates brain activity using information acquired with more than one neurosignal measurement technology. In this paper we describe how to set up and use a hybrid platform based on simultaneous electroencephalography (EEG) and functional magnetic resonance imaging (fMRI), then we illustrate how to use it for conducting bimodal neurofeedback experiments. The paper is in...
[structure: see text] A bimodal target-specific contrast agent based on a cyclic peptide containing the target-specific NGR sequence, gadolinium(III) diethylenetriaminepentaacetic acid (Gd(III)DTPA), and Oregon Green 488 (OG488) suitable for both MR imaging and optical imaging of angiogenesis is developed. The synthetic strategy for this target-specific contrast agent exploits the use of highly...
Early-age drying (immediately after casting) of mortars and the corresponding plastic shrinkage were studied using bimodal neutron/X-ray computed tomography. This novel, correlative 3D imaging mode enabled studying simultaneously without any source spurious perturbation water migration loss processes together with deformations due to shrinkage. Bimodal opens up new possibilities for dynamic cou...
Functional imaging studies of learning and memory have primarily focused on stimulus material presented within a single modality (see review by Gabrieli, 1998, Annu. Rev. Psychol. 49: 87-115). In the present study we investigated mechanisms for learning material presented in visual and auditory modalities, using single-trial functional magnetic resonance imaging. We evaluated time-dependent lea...
ASTER stereo and ASTER infrared (IR) retrieved cloud top heights (CTHs) at 90 m spatial resolution are compared to operational Multi-Angle Imaging SpectroRadiometer (MISR) stereo and MODerate Resolution Imaging Spectroradiometer (MODIS) thermal IR techniques at 1100 m and 5000 m spatial resolution, respectively. ASTER data availability limits this study to trade wind cumulus clouds only. ASTER ...
Neurofeedback is a promising tool for brain rehabilitation and peak performance training. Neurofeedback approaches usually rely on a single brain imaging modality such as EEG or fMRI. Combining these modalities for neurofeedback training could allow to provide richer information to the subject and could thus enable him/her to achieve faster and more specific self-regulation. Yet unimodal and mu...
Downlo mbination of reporter genes for magnetic resonance imaging (MRI) and optical imaging can provide an nal level of noninvasive and quantitative information about biological processes occurring in deep tise developed a bimodal lentiviral vector to monitor deep tissue events using MRI to detect myc-tagged ferritin heavy chain (myc-hFTH) expression and fluorescence imaging to detect green flu...
