THE MECHANISM OF THE SHADOW REFLEX IN CIRRIPEDIA III. RHYTHMICAL PATTERNED ACTIVITY IN CENTRAL NEURONS AND ITS MODULATION BY SHADOWS

The principle finding reported is that there are two classes of bursters, identifiable by location, bursting pattern, and response to "light-off" that exhibit reciprocity.

Ctenophore kairomones and modified aminosugar disaccharides alter the shadow response in a larval crab

The test hypotheses were supported; predator kairomones, ctenophore external mucus, and purified aminosugar disaccharides having acetylamine functionality reduced the threshold decrease in irradiance needed to evoke shadow responses in crab larvae.

Antagonistic Components of the Late Receptor Potential in the Barnacle Photoreceptor Arising from Different Stages of the Pigment Process

Comparison of the action spectra for the stimulus-coincident LRP and for the extended depolarization and its curtailment with those previously measured for the early receptor potential (ERP) confirms that these phenomena derive from the same bi-stable pigment as the ERP.

Early Receptor Potential Evidence for the Existence of Two Thermally Stable States in the Barnacle Visual Pigment

The early receptor potential in the barnacle photoreceptor is shown by intracellular recording to exhibit a strong dependence on the color of the stimulus and of the preceding adaptation, suggesting that two thermally stable pigment states with different absorption spectra contribute to the ERP.

Hyperpolarization of a Barnacle Photoreceptor Membrane following Illumination

Membrane potential changes following illumination of a photoreceptor cell in the lateral ocellus of a barnacle were studied by means of intracellular recording and polarization techniques and it is suggested that the postillumination hyperpolarization is produced by an electrogenic Na pump which is activated by the Na influx during illumination.

THE MECHANISM OF THE SHADOW REFLEX IN CIRRIPEDIA. II. PHOTORECEPTOR CELL RESPONSE, SECOND-ORDER RESPONSES, AND MOTOR CELL OUTPUT

Intracellular sensory potentials from the lateral ocelli of B. eburneus indicate that spiking does not occur in these retinula cells, and that the wave form of the response to a light flash is very similar to comparable records from other arthropod retinul cells.

II. The Photo-electric Efficiency of the Median and the Lateral Photoreceptor of the Barnacle Balanus eburneus

Formulae which were derived in a preceeding publication are used to analize the electrical response to flashes of 10 μsec duration of the median and lateral photoreceptors of the barnacle Balanus eburneus and the method of measuring nerve current extracellularly is applied.

THE MECHANISM OF THE SHADOW REFLEX IN CIRRIPEDIA. I. ELECTRICAL ACTIVITY IN THE SUPRAESOPHAGEAL GANGLION AND OCELLAR NERVE

It is suggested that, at best, third order neurons are responsible for the phasic response in the latter two genera, and evidence is presented that both the primary "on" response and the second order "off" response are grad...

The Ventral Photoreceptor Cells of Limulus III. A voltage-clamp study

The data strongly support the hypothesis that two systems of electric current exist in the membranes of Limulus as the sum of a dark current and a light-induced current.

Rapid Dark Recovery of the Invertebrate Early Receptor Potential

The recovery in the dark of the early receptor potential, as a direct manifestation of the state of the visual pigments, has been studied by intracellular recording in the ventral photoreceptors of

A Visual Pigment with Two Physiologically Active Stable States

Red illumination of a Balanus amphitrite photoreceptor that has been adapted to blue light leads to prolonged depolarization in the late receptor potential, which apparently contribute antagonistically to the early receptor potential.

Simple Photoreceptors in Limulus polyphemus

The "olfactory nerve," the endoparietal eye, and the rudimentary lateral eyes of Limulus (polyphemus) contain simple photoreceptor cells that duplicate many of the electrical responses of the
