“On a fundamental level, I’m fascinated by how one neuron can receive hundreds or even thousands of different synaptic signals and know how to process them. By gaining a deeper understanding of the diversity of synaptic receptors that receive these signals, we are edging closer to finding treatments for a wide range of neurological diseases.”

Studying the diversity of synapses

What are the molecular mechanisms that underlie seizure disorders?

Even when our bodies rest, millions of neuronal cells in our brains are active, firing electrical impulses. Most of the time, these signals are elegantly harmonized through circuits composed of many cells. When disrupted due to disease or brain injury, however, the activity in these circuits can become chaotic. This can lead to epilepsy, psychiatric diseases, or movement disorders, which afflict millions of Americans.

Clinical trials have shown that epilepsy therapies designed to inhibit glutamate receptors, while effective at stopping symptoms in some patients, can also produce intolerable side effects. Dr. Swanger's lab studies subtypes within a glutamate receptor family, called N-methyl-D-aspartate receptors (NMDAR). In particular, the Swanger Lab wants to try modulating the functional behavior of interconnected neurons in the thalamus, a region in the brain involved in seizure generation and where four different NMDAR subtypes are expressed. The Lab also studies Dravet Syndrome, a rare and catastrophic seizure disorder.
