Anatomical Zeta Ganglion Cell

References The basis of this description comes from Berson, Pu and Famiglietti's 1996 ARVO poster #2923.
The Zeta classification is an anatomical distinction for a cat ganglion cell. Zeta cells form "5-15% of the ganglion cell population across the whole retina Berson, Pu and Famiglietti (1996).

• Postsynaptic connections (Input)

• Presynaptic connections (Output)
  • Contralateral Superior Colliculus
  • Not the Dorsal LGN or ipsilateral SC

• Function
  • Perhaps the phasic W or sluggish transient ganglion cell - Berson, Pu and Famiglietti (1996)

• Morphology
  • Berson, Pu and Famiglietti (1996)
    • Soma: 17 um diameter
    • Fine Axon
    • tufted dendritic field
    • 130-550um dendritic field diameter

• Array characteristics
  • Berson, Pu and Famiglietti (1996)
    • Little change in df diameter with changes in eccentricity.
    • Big change in df diameter with distance from visual streak.
    • Doesn't have an "off" counter-part... sugesting an on-off response

• Compartmental Model Characteristics

• Location
  • Berson, Pu and Famiglietti (1996)
    • Stratifies in the "On" sublayer of IPL
    • Unistratified at about S4

• Subclasses

• Synapse types

• Synapse Receptors

• Neurotransmitters

• Immunoreactivity/Stain
  • retrograde transport of fluorescent latex beads.
  • HRP-catalyzed dark reaction

• Nomenclature
  • Introduced by Berson, Pu and Famiglietti (1996)
  • Class IV Berson, Pu and Famiglietti (1996)
