Chemosensory organs as models of neuronal synapses

Open access

Abstract

Neuronal synapses are important microstructures that underlie complex cognitive capacities. Recent studies, primarily in Caenorhabditis elegans and Drosophila melanogaster, have revealed surprising parallels between these synapses and the 'chemosensory synapses' that reside at the tips of chemosensory cells that respond to environmental stimuli. Similarities in the structures, mechanisms of action and specific molecules found at these sites extend to the presynaptic, postsynaptic and glial entities composing both synapse types. In this article I propose that chemosensory synapses may serve as useful models of neuronal synapses, and consider the possibility that the two synapse types derive from a common ancestral structure.

  • The postsynaptic sites and the dendrites of second-order neurons could have evolved from the ciliated endings of their sensory cell precursors.

    “The striking molecular and functional similarities between the sensory endings of neurons (the ‘sensory synapse’) and postsynaptic sites on neuron–neuron synapses [66] suggest that the postsynaptic sites and the dendrites of these second-order neurons could have evolved from the ciliated endings of their sensory cell precursors.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
