title: Horizontal cells of turtle retina: a neurotransmitter control of electrical junctions?
abstract: Recent experiments suggest that GABA and dopamine can modulate the permeability of the electrical junctions between horizontal cells of the turtle retina. The possible significance and functional advantages of a chemical control of the electrical junctions are briefly discussed. A similar mechanism could combine in a network of interacting elements the low energy cost and low intrinsic noise typical of the electrical synapses with the great functional plasticity typical of the chemical transmission.
