[Neurosensitive contacts and new kind of synapses in wall lizard (Lacerta muralis, Laurenti) pineal body].

The neurosensitive synapses between photoreceptor cells and nerve ganglion cells are numerous enough to constitute an additional argument for a photosensitive function of the pineal gland. A new type of synapse, observed between the secretory rudimentary photoreceptor cells and nerve ganglion cells presents a direct relation from cells showing an active secretory function to the central nervous system.
