The possibility that neurons in the basal ganglia and cerebellum innervate areasof the cerebral cortex that are invloved in cognitive function has been a controversial subject. The combined alignment of all of these protons results in a net magnetic moment a subject placed within a magnetic field thus becomes “magnetized.” Over time, random atomic collisions and other perturbations allow the complete system to reach a magnetic and thermal equilibrium with an excess of protons aligned with the magnetic field. When placed within a magnetic field, a torque will be exerted upon them, resulting in a slight energetic advantage of one orientation (parallel to the field) over another (the anti-parallel orientation). The proton nuclei of the hydrogen atom possess a small magnetic moment. Application of a brief radio frequency (RF) electromagnetic pulse disturbs the equilibrium and introduces a transient phase coherence to the nuclear magnetization that can, in turn, be detected as a radio signal and formed into an image.The proton nuclei precess about the applied field at a characteristic frequency, but at a random phase (or orientation) with respect to one another.Various atomic nuclei, particularly the proton nucleus of the hydrogen atom (from here, we will consider only the proton), align themselves with this field and reach a thermal equilibrium. The subject is first placed into a strong and homogeneous magnetic field.To understand the fMRI method, investigators should be familiar with the physical principles of magnetic resonance that determine its signal characteristics, and through which it is possible to form images. This NIH grant is governed by the National Institute of Biomedical Imaging and Bioengineering (NIBIB). LONI Resource is operated by the Laboratory of Neuro Imaging (LONI) at USC and funded by the P41 Biomedical Technology Resource Center award. In doing so, LONIR hopes to foster research relationships that will disseminate new information and train investigators in the use of new techniques. The algorithms and tools developed by LONIR are made available to the neuroscience research community. The goal of the Resource is to develop a collaborative environment equipped with the necessary tools for discovery in brain imaging research.
LONI Resource (LONIR) supports neuroimaging researchers investigating brain structure, function and physiology in health and disease using comprehensive imaging analysis. These protocols illustrate the functionality and utilization of heterogeneous datasets, a number of validated methods and tools for data analysis, as well as web-services for managing brain imaging data. LONI provides trainees with access to a diverse array of neuroimaging research protocols.

Attendees will get acquainted with the Pipeline interface and learn how to describe their own modules and create processing workflows, including a hands-on demonstration of segmentation, shape analysis and cortical thickness workflows. The training course covers how to employ any of the available Pipeline library modules and workflows. The Pipeline environment offers a scalable infrastructure for graphical integration of diverse, complex and heterogeneous software. The LONI Pipeline provides a graphical framework for development, maintenance and dissemination of neuroimaging data-analysis Off-site trainings can be arranged at your institution. On-site trainings are held in the LONI DIVE theatre. Visit our calendar on the News and Events page for information about upcoming scheduled training.

Software training is available for researchers who use LONI software. LONI develops a diverse array of modeling, analysis and visualization software and provides user guides, forums and training workshops demonstrating the use of these computational resources to solve specific biomedical imaging problems.
