Neuroimaging

The OHBM Replication Award is an award presented annually by the Organization for Human Brain Mapping (OHBM). It is presented to a researcher in recognition of conducting and disseminating the results of a neuroimaging replication study of exceptional quality and impact.

Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei. EPR spectroscopy is particularly useful for studying metal complexes and organic radicals. EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford.

Neuroimaging is the use of quantitative (computational) techniques to study the structure and function of the central nervous system, developed as an objective way of scientifically studying the healthy human brain in a non-invasive manner. Increasingly it is also being used for quantitative research studies of brain disease and psychiatric illness. Neuroimaging is highly multidisciplinary involving neuroscience, computer science, psychology and statistics, and is not a medical specialty. Neuroimaging is sometimes confused with neuroradiology.

Ryan C.N. D'Arcy (born 1972) is a Canadian neuroscientist. He is a full professor at Simon Fraser University, where he holds the B.C. Leadership Chair in Multimodal Technology for Healthcare Innovations. He is also the head of Health Sciences and Innovation at Fraser Health's Surrey Memorial Hospital.

Gitte Moos Knudsen (legal name Karen Birgitte Moos Knudsen) is a Danish translational neurobiologist and clinical neurologist, and Clinical Professor and Chief Physician at the Department of Clinical Medicine, Neurology, Psychiatry and Sensory Sciences, at Copenhagen University Hospital. She graduated from Lyngby Statsskole, just north of Copenhagen, before gaining entrance to medicine, where she received her MD from University of Copenhagen in 1984, and became a Board certified user of radioisotopes in 1986. She sat the FMGEMS exam (Foreign Medical Graduates Examination in the Medical Sciences) (US) in 1989. She became Board certified in neurology in 1994 and received her DMSc (Dr.Med.) from University of Copenhagen in 1994. She currently resides in Copenhagen, and is married to Tore Vulpius. She has 3 children.

Professor Rajendra D Badgaiyan (Born 1955) is an Indian-American psychiatrist and cognitive neuroscientist. He is best known for developing a new neuroimaging technique for detection of acute changes in concentration of dopamine released in the live human brain during performance of a cognitive. behavioral or emotional task.

Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3D information. This information is typically presented as cross-sectional slices through the patient, but can be freely reformatted or manipulated as required.

Eyewire is a citizen science game from Sebastian Seung's Lab at Princeton University. It is a human-based computation game that uses players to map retinal neurons. Eyewire launched on December 10, 2012. The game utilizes data generated by the Max Planck Institute for Medical Research.

Neuroradiology is a subspecialty of radiology focusing on the diagnosis and characterization of abnormalities of the central and peripheral nervous system, spine, and head and neck using neuroimaging techniques. Medical issues utilizing neuroradiology include arteriovenous malformations, tumors, aneurysms, and strokes.

Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.
