Enhanced neural plasticity of the primary visual cortex in visual snow syndrome: evidence from magnetoencephalographic gamma oscillations.

ABSTRACT: Visual snow syndrome is a neurological disorder characterized by persistent visual disturbances and associated symptoms. Although the neural basis of the visual snow syndrome remains poorly understood, it may involve increased neuronal excitability and/or altered neuroplasticity in the visual cortex, which could, in turn, affect visual gamma oscillations. An altered excitation-inhibition balance is hypothesized to alter the modulation of gamma power and frequency by stimulation intensity, while maladaptive neuroplasticity may impact time-dependent changes in gamma power during repeated stimulation. To investigate potential alterations in the excitation-inhibition balance and neuroplasticity in visual snow syndrome, we used magnetoencephalography to record visual gamma oscillations in 26 pa
