Migraine is a prevailing disease in present day population. Cortical spreading depression (CSD) - a depolarisation wave that originates in the visual region and propagates across the cortex to the peripheral areas - has been deemed, by several studies, a correlate of visual aura, a neurological phenomenon preceding migraine and causing perceptual disturbance. As of today, little is known about the mechanisms that can trigger or stop such phenomenon. However, the complex and highly individual characteristics of the brain cortex suggest that the

The electric conductivity of atomically thick materials such as graphene yields an effective complex permittivity with a negative real part in the infrared spectrum. This feature allows for the propagation of slowly decaying electromagnetic waves, called surface plasmons-polaritons (SPPs), that are confined near the material interface with wavelengths much shorter than the wavelength of the free-space radiation.
