TLDR
The intracellular response to light of the larval pineal was a hyperpolarization, showing fundamentally the same pattern as that of the adult pineal, and a change of visual pigment in the pineal during metamorphosis is suggested.Abstract:
A comparative study of the larval and adult pineal organs, which are sensitive to incident light, was carried out in the river lampreyLampetra japonica, using intracellular recording from the pineal photoreceptors.read more

Cyclic Nucleotide-Gated Ion Channels
TL;DR: CNG channels are nonselective cation channels that do not discriminate well between alkali ions and even pass divalent cations, in particular Ca2+.

TL;DR: It is discussed that most organisms living under natural conditions express daily rhythms in their behavior, physiology, and biochemistry, and that circadian rhythmicity is a fundamental organizing feature of virtually all organisms.

A cyclic GMP-activated channel in dissociated cells of the chick pineal gland.
Stuart E. Dryer,Dori Henderson +1 more
TL;DR: The first recordings of cyclic GMP-activated channels in an extraretinal photoreceptor are reported, which may be essential for phototransduction in the chick pineal gland.

TL;DR: The discovery of two opsins in the same cell: the blue-sensitive pinopsin and a previously unidentified green-sensitive opsin, which is named parietopsin provides clues about how rod and cone phototransduction might have evolved.

S-potentials from luminosity units in the retina of fish (Cyprinidae)
K. I. Naka,W. A. H. Rushton +1 more
TL;DR: S‐potentials were recorded in fish from units which never responded by depolarization, and these hyperpolarizing units are the L‐units of Svaetichin & MacNichol (1958).

Pineal Regulation of the Body Lightening Reaction in Amphibian Larvae
TL;DR: Body pallor due to contraction of both deep and integumental melanophores occurs when either blinded or normal Xenopus laevis and other amphibian larvae are placed in the dark.

W. C. Cole,John H. Youson +1 more
TL;DR: It is concluded that the pineal organ of P. marinus is a structurally well-developed photosensory and photoneuroendocrine organ that is probably capable of transducing photic stimuli into nervous and endocrine messages to the brain and other organs.
