Visual cortex hyperexcitability in idiopathic generalized epilepsies with photosensitivity: A TMS pilot study

► Healthy subjects have a PT higher than the rMT. ► Patients with IGE without photosensitivity have a PT higher than the rMT. ► Patients with IGE and photosensitivity have a PT lower than the rMT. ► Phosphenes are more frequently reported by patients with photosensitivity. ► A primary visual cortex hyperexcitability characterizes IGE with photosensitivity.
