Our guest today is Richard Edden.
Richard is a professor in the department of Neuroradiology at Johns Hopkins University. He uses a tool — a technology, a method— called Magnetic Resonance Spectroscopy (MRS) to study the brain. Richard’s group focuses on both method development — how can they make MRS better? More informative? — and also what the specific findings mean for brain health.
In this MINI episode, Richard talks to us about spectroscopy and a particular kind of spectroscopy: nuclear magnetic resonance spectroscopy, also known as NMR (and more familiarly, MRI.) Richard talks about why electronegativity, a concept taught in high school and early college chemistry, is essential to how NMR works.

In this mini episode, Dr. Jonathan Bogan explains how insulin triggers the TUG protein to help move GLUT 4 transporter proteins from inside the cell to the cell membrane. There, they transport glucose from the bloodstream into the cell using facilitated diffusion. Tune in next week for the full-length interview. Hosted on Acast.

Dr. Dina Simkin is an Research Assistant Professor at Northwestern University's Feinberg School of Medicine whose research mainly focuses on how on how mutations in ion channel proteins contribute to pediatric epilepsy and neurodevelopmental disorders. Dr. Simkin earned her BS in Biochemistry, and then proceeded to earn PhDs in Neuroscience, Biophysics, and in Cellular and Molecular Pharmacology. She additionally completed post-graduate training in both the neurophysiology of aging and stem cell-derived neuronal models of epileptic channelopathy.

Lydia Pecker, M.D., is a pediatric hematologist and director of research and advocacy at the Sickle Cell Center for Adults at Johns Hopkins University. She previously served as the founding director of the Center's Young Adult Clinic, which was built to support young people transitioning from pediatric to adult care systems. She received her undergraduate degree in Africana studies from Brown University, earned her M.D. at the University of Pennsylvania School of Medicine, and received a Master's degree in Health Sciences from the Bloomberg School of Public Health.
