HPPD is an inter-related dynamic dysfunction between many modalities giving rise the various visual disturbances.
An inhibitory cortical interneuron, which expresses 5-HT2a receptors and releases GABA upon activation in the V1 in the visual cortex and/or in the lateral geniculate nucleus in the thalamus. This will explain after images and halos because inhibitory signals are important to suppress neural response to stimuli.
