A depolarizing aftereffect of intense light in the drone visual receptor.
F. Baumann,B. Hadjilazaro +1 more
TLDR
It is proposed that the afterpotential is due to the extension into the dark period of the same light-initiated process as is responsible for the plateau of the receptor potential.About:

The Physiology of Invertebrate Visual Pigments
TL;DR: The visual pigments of all invertebrates investigated so far are membrane-coupled chromoproteids having similar spectral absorption characteristics, the chromophore of which has been, in certain species, shown to be the same as that of the vertebrate rhodopsin (11-cis-retinal).

The Processing of Color, Motion, and Stimulus Timing Are Anatomically Segregated in the Bumblebee Brain
Angelique C. Paulk,James Phillips-Portillo,Andrew M. Dacks,Jean Marc Fellous,Wulfila Gronenberg +4 more
TL;DR: It is hypothesized that the anatomical layers of the lobula are the structural basis for the segregation of visual information into color, motion, and stimulus timing in the brain.

Visual processing in the central bee brain
Angelique C. Paulk,Andrew M. Dacks,James Phillips-Portillo,Jean Marc Fellous,Wulfila Gronenberg +4 more
TL;DR: Data suggest that neurons along the visual pathway to the central brain not only are segregated with regard to the physical features of the stimuli, but also differ in the way they encode stimuli, possibly to allow for efficient parallel processing to occur.

Role of intracellular calcium and sodium in light adaptation in the retina of the honey bee drone (Apis mellifera, L).
C.R. Bader,F Baumann,D Bertrand +2 more
TL;DR: In the honey bee drone, the decrease in sensitivity to light of a retinula cell exposed to background illumination was found to be accurately reflected by the difference in amplitude between the initial transient depolarization and the lowest steadydepolarization evoked by the background light.
Journal ArticleDOI
Higher order visual input to the mushroom bodies in the bee, Bombus impatiens.
TL;DR: The structure and response of optic lobe (OL) neurons projecting to the calyces of the mushroom bodies in bees were characterized, which included sensory information required for the biologically relevant associations bees form during foraging tasks.

The influence of potassium and chloride ions on the membrane potential of single muscle fibres.
A. L. Hodgkin,P. Horowicz +1 more
TL;DR: The most widely accepted theory of the restirng potential of muscle is that the electrical potential difference between the inside and outside of a muscle fibre arises from the concentration gradients of the potassium and chloride ions.

Effects of sodium, potassium, and calcium ions on slow and spike potentials in single photoreceptor cells.
Bernard W. Fulpius,Fritz Baumann +1 more
TL;DR: An attempt was made to interpret the receptor and spike potentials in terms of passive movements of Na and K across the membrane of the retinula cell in a solution in which all the Na had been replaced by choline, Tris, or sucrose.
Journal ArticleDOI
Slow and Spike Potentials Recorded from Retinula Cells of the Honeybee Drone in Response to Light
TL;DR: Responses to light recorded by means of intracellular microelectrodes in isolated heads kept in oxygenated Ringer solution consist of a slow depolarization and a train of spikes, similar to those observed in Limulus by Fuortes and Hodgkin.
Journal ArticleDOI
The rod after-effect in S-potentials from the cat retina.
TL;DR: It is concluded that the after-effect originates from something that accumulates after the maintained voltage in rod pathways reaches a ceiling, and can continue at a fixed rate irrespective of the bleaching rate.
Journal ArticleDOI
Spike potentials recorded from the insect photoreceptor.
Kén-Ichi Naka,Eisuke Eguchi +1 more
TL;DR: From electron microscopic observation of the drone ommatidium, it was concluded that the response had been recorded from the retinula cell, and the following hypothesis is suggested for the initiation of spike potentials in the drone compound eye.
