[Electric parameters of the L-type horizontal cell layer in the carp retina]

The inner longitudinal resistance of the L-type horizontal cell syncytium in the carp retina ranges from 1.5 X 10(5) to 7,4 X 10(5) Ohm. The static resistance of the nonsynaptic membrane at the potential level corresponding to the bright light ranges from 2,5 X 10(3) to 19 X 10(3) Ohm . cm2 i.e. comparable with membrane resistances of many neurons recently investigated. Depolarization increases the resistance in 3,5 divided by 21 times up to 16 X 10(3) divided by 69.10(3) Ohm . cm2. Measured values of the capacity are 1 divided by 2 mcF . cm-2.
