In the first visual synapse of the insect compound eye, both the presynaptic and postsynaptic signals are graded, nonspiking changes in membrane voltage. The synapse exhibits tonic transmitter release (even in dark) and strong adaptation to long-lasting light backgrounds, leading to changes also in the dynamics of signal transmission. We have studied these adaptational properties of the first visual synapse of the blowfly Calliphora vicina. Investigations were done in situ by intracellular…

Frequency-selective transmission of graded signals in large monopolar neurons of blowfly Calliphora vicina compound eye.
TLDR
It is demonstrated that the complex interaction between the passive membrane properties, Kv conductances, and the neuronal geometry leads to a resonance-like filtering of signals with peak frequencies of transmission near 15 and 40 Hz for L3 and L1/2, respectively.
Spikes and ribbon synapses in early vision
Cellular elements for seeing in the dark: voltage-dependent conductances in cockroach photoreceptors
TLDR
The relative expression of KA and KDR in cockroach photoreceptors was opposite to the previously hypothesized framework for dark-active insects, necessitating further comparative work on the conductances.
BIOPHYSICS OF NIGHT VISION Cockroach (Periplaneta americana) Photoreceptors as a Model System
TLDR
Simulations showed that photoreceptors of nocturnal animals can sacrifice phototransduction precision in their natural illumination without compromising their coding performance, and showed that at such low light levels the physical noise caused byrandom photons determines the information rate and the biological noise, caused by random latency and amplitude of single photon responses, has only a minor effect.

Participation of the histamine receptor encoded by the gene hclB (HCLB) in visual sensitivity control: an electroretinographic study in Drosophila melanogaster
TLDR
The glial histamine receptor HCLB participates in visual sensitivity control at the level of the first synapse of the Drosophila visual system under a wide range of ambient illumination conditions and contributes to the process of light adaptation.
Investigating through multiple experimental approaches how early visual circuit functions affect Drosophila behaviour
TLDR
The flight simulator is used to show that the absence of ‘chromatic’ photoreceptors adversely affects visually-driven optomotor behaviour, and that Ca2+-activated K+ channel mutations in post-synaptic Large Monopolar Cells can affect visual behaviour, but that these effects are often managed by homeostatic mechanisms that serve to maintain biologically-relevant function.

Analog Integrated Circuit for Motion Detection against Moving Background Based on the Insect Visual System
TLDR
It was clarified that the various motion directions of the target can be detected independent of the background by using the proposed network.
Taurine‐, aspartate‐ and glutamate‐like immunoreactivity identifies chemically distinct subdivisions of Kenyon cells in the cockroach mushroom body
The lobes of the mushroom bodies of the cockroach Periplaneta americana consist of longitudinal modules called laminae. These comprise repeating arrangements of Kenyon cell axons, which like their…

Tonic transmitter release in a graded potential synapse.
TLDR
The results strongly suggest that the photoreceptor transmitter release in fly is tonic, even in dark, and further support the modulation of the synaptic voltage transfer by postsynaptic Cl- extrusion.
Transfer of graded potentials at the photoreceptor-interneuron synapse
TLDR
A descriptive synaptic model is described, in which the kinetics of the tonic transmitter (histamine) release from the photoreceptor axon terminals change with mean Photoreceptor depolarization, and it agrees with the recently proposed theory of maximizing sensory information.
Presynaptic enhancement of signal transients in photoreceptor terminals in the compound eye
TLDR
The FDT contributes to the synaptic amplification and boosting of high frequencies that enhance signals at the visual system’s first synapse, and is caused by a voltage-dependent increase in conductance, localized in the photoreceptor axon terminals.
Synaptic limitations to contrast coding in the retina of the blowfly Calliphora
TLDR
It is concluded that retinal antagonism and nonlinear synaptic amplification act in concert to protect receptor signals from contamination by synaptic noise and may explain the widespread occurrence of these processes in early visual processing.
Early Visual Processing in the Compound Eye: Physiology and Pharmacology of the Retina-Lamina Projection in the Fly
TLDR
Intracellular recordings from an intact preparation have been used to analyse synaptic transfer from the photoreceptors to a major class of second order neurones, the large monopolar cells (LMCs), and histamine represents the first case of histaminergic neurotransmission in insects.
Graded Responses and Spiking Properties of Identified First-Order Visual Interneurons of the Fly Compound Eye
TLDR
Results indicate that voltage-gated sodium channels that are normally highly inactivated are responsible for the OFF-spike generation in L3 and L 1, and that probably a component of the light-om response is mediated via the same conductance as well.
Nonlinear models of the first synapse in the light-adapted fly retina.
TLDR
Two possible structural models of the synapse are supported, the first having two parallel paths for signal flow between the photoreceptor and LMC, and the second having two distinct nonlinear operations, occurring before and after chemical transmission.
Synaptic Chloride Channels Generating Hyperpolarizing On-Responses in Monopolar Neurones of the Blowfly Visual System
TLDR
The large monopolar neurones LI and L2 in the first optic ganglion of dipteran flies are postsynaptic to short-fibre photoreceptors and the nature of the ionic source generating the hyperpolarizing response of monopolar cells has been rather inconclusive.
Short-term synaptic plasticity.
TLDR
The evidence for this hypothesis, and the origins of the different kinetic phases of synaptic enhancement, as well as the interpretation of statistical changes in transmitter release and roles played by other factors such as alterations in presynaptic Ca(2+) influx or postsynaptic levels of [Ca(2+)]i are discussed.
Mechanisms for Neural Signal Enhancement in the Blowfly Compound Eye
TLDR
It is concluded that LMCs are essentially passive integrators of a well-regulated direct input from the photoreceptors, suggesting that the intrinsic properties of photoreceptor-LMC synapses and presynaptic interactions are primarily responsible for amplification and antagonism.
