The overarching hypothesis for the Kramer Lab is that axons have an active and unexplored role in neurotransmission.
Axons can compute information and generate output that contributes to behavior and the etiology of neurological diseases, much like the somatodendritic compartment. We aim to study foundational mechanisms of neuronal signaling and physiology, and use that to better understand the brain and its diseases.
