Teleost Mauthner cap cells: intimate contact by gap junctions.

T Schuster, A Schwartz

    Journal Fur Hirnforschung
    |January 1, 1984
    PubMed
    Summary

    Glial cap cells in rainbow trout form a barrier around the Mauthner cell axon. Gap junctions between these cells suggest they function as a unified electrical system, contributing to axon resistance.

    Area of Science:

    • Neuroscience
    • Cell Biology
    • Glial Cell Biology

    Background:

    • The Mauthner cell is a crucial component of the escape response in fish.
    • Glial cells form a specialized ensheathment, the axon cap, around the Mauthner cell axon.

    Purpose of the Study:

    • To investigate the cellular composition and structural organization of the glial cap cells in rainbow trout.
    • To explore the role of gap junctions in the function of the glial cap.

    Main Methods:

    • Morphological analysis of glial cells ensheathing the Mauthner cell axon.
    • Identification of cell types, including astrocytes and oligodendrocytes.
    • Examination of intercellular connections, specifically gap junctions.

    Main Results:

    • The glial cap consists of a double-layered arrangement of fibrous astrocytes and occasional oligodendrocytes.
    • Numerous gap junctions connect glial cells, particularly between astrocyte somata.
    • These junctions suggest the glial cap cells may function as an electrophysiological unit.
    • The densely packed glial elements contribute to high axon cap resistance.

    Conclusions:

    • Glial cap cells in rainbow trout form a structurally organized barrier around the Mauthner cell axon.
    • Astro-astrocytic gap junctions are prevalent and likely contribute to the formation of this resistive barrier.
    • The glial network may operate as a functional syncytium, influencing axonal properties.
