Abstract: Multispectral Imaging Enables Visualization of Spreading Depolarizations in Gyrencephalic Brain
Spreading Depolarization (SD) is a phenomenon in the brain related to the abrupt depolarization of neurons in gray matter which results from a break-down of ion gradients across the neuron membrane and propagates like a wave of ischemia. While modulating the hemodynamic response of the SDs is a therapeutic target, the lack of imaging methods that allow for monitoring SDs with high spatiotemporal resolution hinder progress in the field. In this work, we address this bottleneck with a new method for brain imaging based on multispectral imaging (MSI).
