Functional and Structural Magnetic Resonance Imaging of Humans and Macaques [PDF]

open access: yes, 2004
Magnetic resonance imaging (MRI) is a technique which finds use in the neurosciences both as an anatomical and functional localization tool. The traditional uses of MRI for structural analysis, such as are commonly found in medicine, can be adapted to ...

IMAGE ANALYSIS OF FUNCTIONAL MAGNETIC RESONANCE IMAGING [PDF]

open access: yesBiomedical Engineering: Applications, Basis and Communications, 2001
Functional MRI can provide important new insights into the phenomenon of brain activity through improved temporal and spatial resolution as well as easiness and safety on repeated or prolonged examination. A revolutionary renewal on the knowledge of functional anatomy of the human brain based on the pre-fMRI technology is thus possible.

Functional imaging of plants: A nuclear magnetic resonance study of a cucumber plant [PDF]

open access: yes, 2002
Functional magnetic resonance imaging was used to study transients of biophysical parameters in a cucumber plant in response to environmental changes. Detailed flow imaging experiments showed the location of xylem and phloem in the stem and the response ...

Functional magnetic resonance imaging [PDF]

open access: yes, 2012
Introduction Functional magnetic resonance imaging (fMRI) allows the non-invasive measurement of neural activity nearly everywhere in the brain. The structural predecessor, MRI, was invented in the early 1970s (Lauterbur, 1973) and has been used clinically since the mid-1980s to provide high-resolution structural images of body parts, including rapid

On the reconstruction of magnetic resonance current density images of the human brain: Pitfalls and perspectives

open access: yesNeuroImage, 2021
Magnetic resonance current density imaging (MRCDI) of the human brain aims to reconstruct the current density distribution caused by transcranial electric stimulation from MR-based measurements of the current-induced magnetic fields.

The neuronal correlate of bidirectional synesthesia: a combined event-related potential and functional magnetic resonance imaging study [PDF]

open access: yes, 2007
The neuronal correlate of a rare explicit bi-directional synaesthesia was investigated with numerical and physical size comparison tasks using both functional magnetic resonance imaging and event-related potentials. Interestingly, although participant I.
