Tran N H Nguyen, James K Nolan, Hyunsu Park, Stephanie Lam, Mara Fattah, Jessica C Page, Hang-Eun Joe, Martin B G Jun, Hyungwoo Lee, Sang Joon Kim, Riyi Shi, Hyowon Lee,

Glutamate excitotoxicity is a pathology in which excessive glutamate can cause neuronal damage and degeneration. It has also been linked to secondary injury mechanisms in traumatic spinal cord injury. Conventional bioanalytical techniques used to characterize glutamate levels in vivo, such as microdialysis, have low spatiotemporal resolution, which has impeded our ... Read more >>
