Photic cycle
WebThe photic driving response and the photic hypersensitivity are similar as both are induced by light stimulation. The photic driving response in a high-stimulation region of 15 Hz or more (an H-response) is thought to be abnormal, and migraine patients frequently show the H-response during the interictal phase [4]. WebFeb 16, 2024 · Photic input received directly and indirectly by melanopsin containing intrinsically photosensitive retinal ganglion cells (ipRGCs) projecting to the SCN through excitatory PACAP and glutamate projections. ipRGCs have also dense glutamatergic projections to the IGL, where they interact with the non-photic pathway.
