The Waiting Is Over

March 18, 2015

Synapses, the links between neurons that allow them to pass information to one another, are central to all the brain’s functions. These key building blocks are believed to be where memories are stored, yet researchers…

Memories Illuminated

June 19, 2013

Oscar Wilde called memory “the diary that we all carry about with us.” Now a team of USC Dornsife scientists has developed a way to see where and how that diary is written. Led by Don Arnold and Richard Roberts,…

Video Illuminates a Brain Cell

August 27, 2012

Using bioluminescent proteins from a jellyfish, a team of scientists has lit up the inside of a neuron, capturing video footage that shows the movement of proteins throughout the cell. The video offers a rare peek at how…

Don Arnold is the recipient of a 2012 Technological Innovations in Neuroscience Award presented by the McKnight Endowment Fund for Neuroscience. Arnold will use the funding to study how intracellular antibody-like molecules called intrabodies can be used to target and eliminate proteins in living cells. Photo by Jie Gu.

Arnold Wins McKnight Award

July 27, 2012

Don Arnold, associate professor of biological sciences in USC Dornsife, has received the 2012 McKnight Technological Innovations in Neuroscience Award. The award supports scientists working on new and unusual approaches to…

Motors on a Mission

March 23, 2011

Within each of our bodies are billions of neurons. These cells relay chemical and electrical signals, forming vast networks that comprise the human nervous system. Within each neuron is a microscopic network of its own, a…
