title: Photosensitive neurons in mollusks.
abstract: In addition to regular photoreceptors, some invertebrates possess simple extraocular photoreceptors. For example, the central ganglia of mollusks contain photosensitive neurons. These neurons are located on the dorsal surface of the ganglia and based on their electrophysiological properties, it has been postulated that they are the internal photoreceptors. However, besides the eye, transduction of the light also occurs in these extra-ocular photoreceptors. In the present work, we analyse the reactivity of these nerve cells to light and describe the underlying mechanism mediating the light-induced response.
